Abstract 16
A series of new benzimidazole-thiazolidinedione hybrids has been synthesized and
evaluated for their cytotoxic potential against a selected human cancer cell lines of
prostate (PC-3 and DU-145), breast (MDA-MB-231), lung (A549) and a normal
breastepithelial cells (MCF10A). Among the tested compounds, 11p exhibited
promising cytotoxicity with IC50 value of 11.46 ± 1.46 μM on A549 lung cancer cell
line and did not show significant toxicity on normal MCF10A cells. Lung cancer cells
(A549) have been used to know the mechanism of cell growth inhibition and
apoptosis inducing effect with compound 11p. The treatment of A549 cells with 11p
showed typical apoptotic morphology like cell shrinkage, chromatin condensation
and horseshoe shaped nuclei formation. Flow-cytometry analysis revealed the G2/M
phase of cell cycle arrest in a dose dependent manner. Preliminary mechanistic
studies suggested that the cell migration was inhibited through the disruption of F-
actin protein.

Abstract
The use of energy restriction mimetic agents (ERMAs) to selectively target cancer
cellsaddicted to glycolysis could be a promising therapeutic approach.
Thiazolidinediones (TZDs) are synthetic agonists of the nuclear receptor
peroxisome
proliferator-activated receptor (PPAR)γ that were developed to treat type II diabetes.
These compounds also display anticancer effects which appear mainly to be
independent of their PPARγ agonist activity but the molecular mechanisms involved
in the anticancer action are not yet well understood. Results obtained on ciglitazone
derivatives, mainly in prostate cancer cell models, suggest that these compounds
could act as ERMAs. In the present paper, we introduce how compounds like 2-
deoxyglucose target the Warburg effect and then we discuss the possibility that the
PPARγ-independent effects of various TZD could result from their action as ERMAs.
Graphical Abstract 19
Warburg effect
As observed by Otto Warburg in the 1920s, the metabolic properties of cancer cells differ
markedly from those of normal cells. Indeed, cancer cells have elevated rates of glucose
consumption and high lactate production but unlike normal cells, lactate production
occurs even in the presence of oxygen. This is known as aerobic glycolysis orWarburg
Effect [1]. High glucose uptake of cancer tissues is clinicallyused to diagnose cancer and
to monitor tumor response to treatmentby imaging uptake
Targeting cancer cell metabolism with2-deoxyglucose 20
The existence of a cancer-specific metabolism and the fact that manycancer cells display a greater
sensitivity to
glucose-deprivation-induced cytotoxicity than normal cells explain why dietary energy restriction is a
potent inhibitor of carcinogenesis.Nevertheless, in Human, it is difficult to sustain chronic caloric restriction
through reduced energy intake. It is better to use ERMAs in order to cause a state of glucose starvation in
cancer cells without limiting caloric intake. This

Thiazolidinediones (TZD), including Troglitazone (TGZ, Sankyo), Rosiglitazone (RGZ, GlaxoSmithKline) and
Pioglitazone (PGZ, Takeda Pharmaceuticals), constitute a family of synthetic compoundscharacterized by a
thiazolidine-2,4-dione ring(Fig. 2). TZD are agonists of the Peroxisome Proliferator Activated Receptor
gamma (PPARγ), a ligand-activated transcription factor belonging to the steroid hormone receptor
superfamily, that were clinically used for the treatment of noninsulin-dependent type 2

Abstract
27
Histone deacetylases (HDACs) are being explored as a therapeutic targetfor
interventions in different types of cancer. HDAC8 is a class I HDAC that is
implicated as a therapeutic target in various indication areas, including different
types of cancer and particularly childhood neuroblastoma. Most previously
described HDAC8-selective inhibitors contain a hydroxamate function as zinc
binding group (ZBG) to confer potency. However, hydroxamate class HDAC
inhibitors have raised increasing concerns about their mutagenic character.
Therefore,
non-hydroxamate based inhibitors could prove to be safer than
hydroxamates. In the present work, a series of novel
5-naphthylidene-2,4-thiazolidinedione was designed and evaluated as potential
antiproliferative agents targeting selectively HDAC8 enzyme. Eleven novel derivatives
were synthesized, purified and characterized by spectroscopic techniques.
Compounds 3k and 3h was found to be most potent selective inhibitors of HDAC8
with IC50 values of 2.7 μM and 6.3 μM
respectively. 3a to 3i was found to be most cytotoxic in leukemic cell lines. 3a and 3 h
both were found to induce apoptosis and cause cell cycle arrest in G2/M phase.

Design and evaluation of non-carboxylate 5 arylidene-2
thioxo-4-imidazolidinones as novel non-competitive
inhibitorsof protein tyrosine phosphatase 1B
Highlights
• 5-arylidene-2-thioxo-4-imidazolidinones 7 are novel PTP1B allosteric
inhibitors.
• Most of compounds 7 proved to be interesting PTP1B inhibitors.
• Compound 7e was shown to be a potent insulin-sensitizing agent in HepG2
cells.
• SAR, molecular docking and kinetic studies were carried out.
Abstract 33
Protein tyrosine phosphatase 1B (PTP1B) acts as a negative regulator of
insulin and leptin signalling and is crucially involved in the development
of type 2 diabetes mellitus, obesity, cancer and neurodegenerative
diseases. Pursuing our efforts to identify PTP1B inhibitors endowed with
drug-like properties, we designed and evaluated
3-aryl-5-arylidene-2-thioxo-4-imidazolidinones (7) as a novel class of
non-carboxylate PTP1B inhibitors. In agreement with our design, kinetic
studies demonstrated that selected compounds 7 act as reversible,
non-competitive inhibitors of the target enzyme at low micromolar
concentrations. Accordingly, molecular docking experiments suggested
that these inhibitors can fit an allosteric site of PTP1B that we previously
individuated. Moreover, cellular assays demonstrated that compound 7e
acts as a potent insulin-sensitizing agent in human liver HepG2 cells.
Taken together, our results showed that these non-competitive PTP1B
inhibitors can be considered promising lead compounds aimed to enhance
druggability of the target enzyme and identify novel antidiabetic drugs.

Abstract
The electronic structure of 5-arylidene-2,4-thiazolidinediones has beenstudied by using 36
experimental and theoretical methodology. The theoretical calculations of the investigated
5 arylidene-2,4-thiazolidinediones have been performed by the use of quantum chemical
methods. The calculated 13C NMR chemical shifts and NBO atomic charges provide an insight
into the influence of such a structure on the transmission of electronic substituent effects.
Linear freeenergy relationships (LFERs) have been further applied to their 13C NMR chemical
shifts. The correlation analyses for the substituent-induced chemical shifts (SCS) have been
performed with σ using SSP (single substituent parameter), field (σF) and resonance (σR)
parameters using DSP (dual substituent parameter), as well as the Yukawa–Tsuno model. The
presented correlations account satisfactorily for the polar and resonance substituent effects
operative at Cβ, and C7 carbons, while reverse substituent effect was found for Cα. The
comparison of correlationresults for the investigated molecules with those obtained for seven
structurally related styrene series has indicated that specific
cross-interaction of phenyl substituent and groups attached at Cβ carbon causes increased
sensitivity of SCS Cβ to the resonance effect with increasing of electron-accepting capabilities
of the group present at Cβ.

Extension of the neuroprotective timewindow for thiazolidinediones in
ischemic stroke is dependent on time of reperfusion
Abstract
Stroke is a leading cause of death and disability but has limited therapeutic options. Thiazolidinediones (TZDs),
agonists for the nuclear receptor, peroxisome proliferator-activated receptor (PPAR)γ, reduce infarct volume and
improve neurologic function following transient middle cerebral artery occlusion (MCAO) in rats. Translation of
these findings into clinical therapy will require careful assessment of dosing paradigms and effective time windows
for treatment. Understanding the mechanisms by which TZDs protect the brain provides insight into how time
windows for neuro protection might be extended. We find that two TZDs, pioglitazone and rosiglitazone,
significantly reduce infarct volume at doses similar to those used clinically (1 mg/kg for pioglitazone and 0.1 mg/kg
for rosiglitazone). We also find that pioglitazone reduces infarctionvolume in a transient, but not a permanent
MCAO model suggesting that reperfusion plays an important role in TZD mediated neuro protection.
Since PPAR γ agonists reduce inflammation and oxidative stress, both of which are exacerbated by reperfusion,
we hypothesized that TZDs wouldbe most effective if administered prior to reperfusion. We administered TZDs 3
h after MCAO and found that infarction volume and neurologic function are significantly improved in animals
perfused at 3 h and 15 min (after TZD treatment), but not in animals reperfused at 2 h (before TZD treatment)
when assessed either 24 h or 3 weeks after MCAO. While TZDs reduce intercellular adhesion molecule (ICAM)
expression to a similar extent regardless of the time of reperfusion, leukocyte entry into brain parenchyma is
more dramatically reduced when reperfusion is delayed until after drug treatment. The finding that delaying
reperfusion until after TZD treatment is beneficial despite a longer period of ischemia,is dramatic given the
widely held view that duration of ischemia is the most important determinate of injury.

• Capsaicin induces apoptosis in glioblastoma LN-18 cells.
• Capsaicin-induced apoptosis is not dependent on TRPV1.
• Capsaicin increases PPARγ expression in glioblastoma LN-18 cells.
• Capsaicin and rosiglitazone/pioglitazone evoke synergistic pro-apoptotic
effect.
Abstract
Capsaicin (N-vanillyl-8-methyl-alpha-nonenamide), a spicy, neurotoxic
42
component of hot pepper is a ligand of vanilloid type-I (TRPV1) receptor
ofanti-cancer potential. However, molecular mechanism of its action is
not fully understood. We found that capsaicin stimulated intrinsic and
extrinsic pathway of apoptosis in human glioblastoma LN-18 cell line
and this phenomenon was not dependent on TRPV1. Activation of
peroxisome proliferator-activated receptor gamma (PPARγ), a ligand-
dependent transcription factor, also induced apoptosis in glioblastoma
cells.
Although PPARγ ligands (thiazolidinediones – rosiglitazone,
pioglitazone)promoted apoptosis in LN-18 cells, capsaicin augmented
this effect. We found that capsaicin in a dose dependent manner induced
expression of PPARγ in glioblastoma LN-18 cells. These findings suggest
that
capsaicin-dependent up-regulation of PPARγ represent the mechanism
foraugmentation of cell death by thiazolidinediones.

1. Introduction
44
Gliomas are relatively rare (incidence rate about 1 per 20000 persons) primary intracranial
tumor, representing 81 % of malignant brain tumors[1]. Glioblastoma, the most common glioma,
is one of the most aggressive brain tumors [2]. Despite significant progress in therapy of this type
of cancer, its effectiveness is still low. The main reason is that central nervous system is protected
by blood-brain barrier against of most anticancer agents [3]. This natural barrier protects glioma
cells and limitssystemic chemotherapy to few agents, in particular temozolomide, an alkylating
pro-drug [4]. However, several in vitro studies suggested
anti-neoplastic potential of capsaicin.
Another apoptosis-inducing factors in glioma cells are thiazolidinediones [[20], [21], [22], [23],
[24], [25]]. This group of drugs were bring to marketas antidiabetic agents, that function
primarily by increasing insulin sensitivity [26]. Thiazolidinediones are ligands for the
peroxisome proliferator-activated receptor-γ (PPARγ), known as a ligand-activated
transcription factor. PPARγ is activated by several known endogenous lipophilic ligands
emerging from the metabolism of arachidonic acid and linoleic acid as well as synthetic
thiazolidinediones [27]. PPARγ has two isoforms: PPARγ1 which is expressed in nearly most
tissues and PPARγ2 detected only in adipocytes [28,29]. PPARγ is expressed in various cancer
cells, including glioblastomas [[20], [21], [22], [23], [24], [25]]. It has beenfound that activation
of PPARγ was accompanied by several antineoplastic effects in human glioblastoma cell lines
[29].

Abstract
A novel dicyanoisophorone (DCI)-based NIR fluorophore employing 2, 4-thiazolidinediones as the modification site
was designed for fluorescence imaging. The fluorophore was assessed as a switchable reporter for H2O2 and the probe
exhibited lysosomes-targeted, a large turn-on fluorescence signal at 720 nm with a large stokes shift (150 nm)
and can be used in biological systems. The ability of the novel fluorophoreto emit NIR fluorescence through a “turn-on”
activation mechanism makes it a promising fluorophore for in vivo imaging applications. The strategy of introducing the
thiazolidinediones with the easy modification site into the fluorophore has a good application prospect to expand the
application of the NIR fluorophore.

Abstract 59
Thiazolidinedione (TZD) is a novel peroxides proliferator activated receptor
γ (PPARγ) agonist with many side effects. Herein, we developed aseries of
novel TZD analogues as partial agonists targeting PPARγ. The study of anti-
hyperglycemic activity and anti-inflammatory activity enabled us to
identify a novel compound, 4 g, which quickly recover the blood glucose of
mice at the concentration of 100 mg/kg, and show similar anti-
inflammatory activity to ibuprofen at the concentration of 20 mg/kg.The
competitive binding assay confirmed direct binding of 4 g to the LBD of
PPARγ with IC50 being 1790 nM, and dose-dependently increased the
transcriptional activity of PPARγ. Besides, through computer-aided drug
design software simulation docking, it was found that compound 4 g
showed the best binding ability to target protein PPARγ. Furthermore,
because of the introduction of benzene containing group at N3 position, the
stability of H12 in the active pocket is reduced and the stability of H3 and β-
fold is increased, showing the characteristics of some PPARγ agonists,
based on the docking model analysis. Together, these results suggest that 4
g is a promising PPARγ agonist that deserves further investigation.

Abstract
Background & Aims
Hepatocellular carcinoma (HCC) remains a leading cause of
cancer-related death worldwide. Effects of second-line oral antidiabeticmedications on incident HCC
risk in individuals with type 2 diabetes mellitus remain unclear. This study evaluated associations
between sulfonylureas, thiazolidinediones, meglitinides and alpha-glucosidase inhibitors, and
incident HCC risk.
Methods
We systematically reviewed all studies on PubMed, Embase and Web of Science databases. Studies were
included if they documented: (1) exposureto oral antidiabetic medication classes; (2) HCC incidence; (3)
relative risks/odds ratios (OR) for HCC incidence. Eight eligible observational studies were identified.
We performed random-effects meta-analyses to calculate pooled adjusted ORs (aORs) and 95%
confidence intervals (CI).
Results 62
Thiazolidinedione use (7 studies, 280,567 participants, 19,242 HCC cases) was associated with
reduced HCC risk (aOR = 0.92, 95% CI = 0.86–0.97, I2 = 43%), including among Asian subjects
(aOR = 0.90, 95% CI = 0.83–0.97), but not Western subjects (aOR = 0.95, 95% CI = 0.87–1.04).
Alpha-glucosidase inhibitor use (3 studies, 56,791 participants, 11,069 HCC cases) was
associated with increased HCC incidence (aOR = 1.08; 95% CI = 1.02–1.14, I2 = 21%).
Sulfonylurea use (8 studies, 281,180 participants, 19,466 HCC cases) was associated with
increased HCC risk in studies including patients with established liver disease (aOR = 1.06,
95% CI = 1.02–1.11, I2 = 75%). Meglitinide use (4 studies, 58,237 participants, 11,310 HCC cases)
was not associated with HCC incidence (aOR = 1.19; 95% CI = 0.89–1.60, I2 = 72%).
Conclusions
Thiazolidinedione use was associated with reduced HCC incidence in Asian individuals with diabetes.
Alpha-glucosidase inhibitor or sulfonylurea use was associated with modestly increased HCC risk;
future research should determine whether those agents should be avoided in patients with chronic
liver disease.

diabetes mellitus independently increases the risk of multiple cancers, including HCC [[2], [3], [4]], and occurs
frequently with concurrent liver disease. Informed selection of antidiabetic regimens may enable providers to mitigate
risk of HCC development in high-risk patientswith diabetes. Given the rapidly increasing prevalence of diabetes, such a
strategy could translate to a considerable decline in overall HCC incidence.
Robust evidence from clinical and epidemiological studies indicates that the risk of HCC in diabetic subjects increases
with insulin use, and decreases with metformin use [[5], [6], [7], [8], [9], [10], [11], [12], [13], [14], [15], [16]]. However,
the effects of second-line oral antidiabetic agents are less well-characterized, and published data are limited and
conflicting. Two prior meta-analyses have reported thiazolidinedione use to be associated with significantly decreased
HCC incidence [17,18], however, Singh et al. did not identify a significant protective association [15], and several recent
studies examining thiazolidinediones in relation toHCC incidence were not included in those prior meta-analyses
[19,20].
Similarly, while prior meta-analyses have indicated use of sulfonylureasto be associated with significantly increased
risk of incident HCC [8,15], they did not include several important, more recent additions to the literature [19,21,22].
Finally, prior meta-analyses of second-line antidiabetic therapies did not evaluate meglitinides, and while a single
meta-analysis reported a trend towards decreased risk of liver cancer in users of alpha-glucosidase inhibitors,
compared to non-users [23], a subsequent analysis by Bosetti et al. [20] found an increased risk of HCC among users
of alpha-glucosidase inhibitors. In light of the growing bodyof primary literature, an updated review of associations
between the use of anti-diabetic medications and risk of incident HCC is warranted.
Therefore, we undertook a systematic review of published literature, and performed a series of meta-analyses to
characterize the relationships between use of second-line oral antidiabetic medication classes and risk ofincident HCC.
Search strategy
A medical librarian (LP) systematically searched PubMed, Embase and Web of Science databases (inception
through March 2020), using keywords and controlled vocabulary (Supplementary Table 1). Titles and
64
abstracts of identified studies were screened by two independent reviewers (AA and ZM), and studies that did
not investigate the association of interest were excluded. Full texts of the remaining studies were reviewed, and
their references examined to identify additional articles of relevance.
Search results
Our search strategy yielded 10,105 individual articles, of which 56 were assessed in full for eligibility. Of
these, 7 studies were published solely in abstract form, and were excluded. 8 studies utilized the Taiwan
National Health Insurance claims database to establish their patient cohort [[30], [31], [32], [33], [34], [35],
[36], [37]], and 2 studies utilized the South Korean National Health Insurance Service-National Sample
Cohort [19,38]: the 2 studies with the largest respective cohort
Discussion
Type 2 diabetes is projected to continue increasing in prevalence during the coming decade [42] and is
frequently comorbid with liver disease (in particular non-alcoholic fatty liver disease). Therefore, informed
and judicious selection of antidiabetic therapy in patients with concurrent diabetes and liver disease
could translate to a meaningful decline in overall rates of incident HCC. We conducted a
comprehensive systematic

• The thiazolidinedione scaffold was modified to target the FOXM1protein, selectively.
• “Direct” FOXM1 inhibition requires a π-sulfur binding interaction.
• FOXM1 inhibitors exert weak binding interactions, suggesting the needfor a different strategy.
Abstract
This research article describes an approach to modify the thiazolidinedione scaffold to produce test drugs capable of binding
to, and inhibit, the in vitro transcriptional activity of the oncogenic protein FOXM1. This approach allowed us to obtain
FOXM1 inhibitors that bind directly to the FOXM1-DNA binding domain without targetingthe expression levels of Sp1, an
upstream transcription factor protein known to activate the expression of FOXM1. Briefly, we modified the chemical structure
of the thiazolidinedione scaffold present in anti-diabetic medications such as pioglitazone, rosiglitazone and the former anti-
diabetic drug troglitazone, because these drugs have been reported to exert inhibition of FOXM1 but hit other targets as well.
Afterthe chemical synthesis of 11 derivatives possessing a modified thiazolidinedione moiety, we screened all test compounds
using in vitroprotocols to measure their ability to (a) dissociate a FOXM1-DNA complex (EMSA assay); (b) decrease the
expression of FOXM1 in triple negative-breast cancer cells (WB assay); (c) downregulate the expression of FOXM1
downstream targets (luciferase reporter assays and qPCR); and inhibit the formation of colonies of MDA-MB-231 cancercells
(colony formation assay). We also identified a potential binding mode associated with these compounds in which compound
TFI-10, one of the most active molecules, exerts binding interactions with Arg289, Trp308, and His287. Unlike the parent drug,
troglitazone, compound TFI-10 does not target the in vitro expression of Sp1, suggesting that it is possible to design FOXM1
inhibitors with a better selectivity profile.

Abstract 73
Thiazolidinediones (TZD), benzopyrans are the proven scaffolds for inhibiting Aldose
reductase (ALR2) activity and their structural confluence with the retention of necessary
fragments helped in designinga series of hybrid compounds
2-(5-cycloalkylidene-2,4-dioxothiazolidin-3-yl)-N-(2-oxo-2H-chromen-3-yl
)acetamide (10a-n) for better ALR2 inhibition. The compounds were synthesized by treating
substituted 3-(N-bromoacetyl amino)coumarins(9a-d) with potassium salt of 5-cyclo
alkylidene-1,3-thiazolidine-2,4-diones (4a-d). The inhibition activity against ALR2 with
IC50 values range from 0.012 ± 0.001 to 0.056 ± 0.007μM.
N-[(6-Bromo-3-coumarinyl)-2-(5-cyclopentylidene-2,4-dioxothiazolidin-3- yl)] acetamide
(10c) with cyclopentylidene group on one end and the
5 bromo group on the other end showed better inhibitory property (IC50 =
0.012 μM) and selectivity index (324.166) against the ALR2, a forty fold superiority over
sorbinil, a better molecule over epalrestat and rest of the analogues exhibited a far superior
response over sorbinil and slightly better as compared with epalrestat. It was further
confirmed by the insilico studies that compound 10c showed best inhibition activity among
the synthesized compounds with a high selectivity index against the ALR2. In invivo
experiments, supplementation of compound 10c to STZ induced rats delayed the progression
of cataract in a dose-dependent manner warranting its further development as a potential
agent to treat the diabetic secondary complications especially cataract.

Confluence of two promising skeletons helped in planning the design of thetest compounds
10a-n as selective aldose reductase II inhibitors, in which 10c emerged as the potent inhibitor
in arresting the progression of cataract, creating interest further in the treatment in a

Methylene Thiazolidinediones as Alkylation Reagents in Catalytic C–
HFunctionalization: Rapid Access to Glitazones
ABSTRACT
The straightforward and rapid incorporation of a thiazolidinedione scaffold
into prefunctionalized (hetero)aromatic compounds is in demandfor the
development of antidiabetic glitazones and other pharmaceuticals. Herein, we
report the unprecedented N- and O-directed C–H alkylation of various
(hetero)arenes with methylene thiazolidinediones under rhodium(III)
catalysis. The applicability of the developed protocol in challenging contexts is
exhibited by the late-stage installation of a methylene thiazolidinedione
moiety on the C–H bond of commercially available drug molecules. Combined
mechanistic investigations aided the elucidation of a plausible reaction
mechanism.

New 1,2,3‐Triazole‐Tethered Thiazolidinedione Derivatives:
Synthesis, Bioevaluation and Molecular Docking Study
Abstract
In search of new active molecules, a small focused library of 1,2,3-triazoles
based 2,4-thiazolidinedione derivatives has been efficiently prepared via the
click chemistry approach. Several derivatives were exhibited excellent anti-
inflammatory activity compared to the standard drug. Further, the synthesized
compounds were found to have potential antioxidant activity. Furthermore, to
rationalize the observed biological activity data, the molecular docking study
has also been carried out against the active site of inflammation enzyme
PPARγ, which revealed a significant correlation between the binding score and
biological activity for these compounds.
The results of the in vitro and in silico study suggest that the triazole
incorporated 2,4-thiazolidinedione derivatives may possess the ideal
structural requirements for the further development of novel therapeutic
agents.

Researchers have investigated various approaches to avoid corrosionproblems in different industries in
recent decades. In line with the research trend in this field, we synthesized and characterized two
thiazolidinedione derivatives, namely (Z)−
5-(4-hydroxy-3-methoxybenzylidene)thiazolidine-2,4-dione (HMTZD) and(Z)− 5-(4-
fluorobenzylidene)thiazolidine-2,4-dione (FTZD), and then used them as potential inhibitors for protecting
the corrosion of carbon steel (CS) in 1.0 mol/L. Corrosion inhibition performances were evaluated using
electrochemical techniques such as electrochemical impedance spectroscopy (EIS), potentiodynamic
polarization (PDP), linear polarization resistance (LPR), and surface characterization using a scanning
electron microscope (SEM). Besides, first principles Density Functional Theory (DFT) calculations were
employed to investigate the potential bonding and charge transfer between inhibitor molecules and Fe(110)
surface. Electrochemical results indicated that the addition of tested inhibitors to corrosive 1.0 mol/L HCl
solution significantly reduced
carbon steel corrosion by increasing the polarization resistance and blocking both anodic and cathodic
corrosion reactions. Further, results indicated that HMTZD and FTZD are adsorption inhibitors following
Langmuir adsorption isotherm. The HMTZD demonstrated an inhibition performance of 96% at 5 × 10-3 M. In
addition, the morphological analysisrevealed the formation of a protective barrier onto the CS surface,
which reduced corrosion attack. The adsorption mechanism was further evaluated using first-principles DFT
calculations, which showed that bothinhibitors can form chemical bonds with Fe-atoms. Partial density of
states (PDOSs) suggested that inhibitor molecules adsorbed through charge transfer between oxygen/sulfur
of molecules and Fe-atoms. The outcomes from the present work are intended to encourage further
exploration of thiazolidinediones in the corrosion protection of metals.

Abstract 83
Diabetes-associated complications are a major global health concern. In diabetics, the increased
accumulation of sorbitol, produced via overactivated polyol pathway, from glucose by the action
of aldose reductase (AR, ALR2, or AKR1B1), has been associated with
life-threatening co-morbidities. Aldose reductase is crucial in detoxifying certain hazardous
aldehydes. However, aldose reductase overexpression in the hyperglycemic state results in
microvascular andmacrovascular diabetic complications through the consequences of the
activated polyol pathway. Accordingly, aldose reductase inhibition hasbeen identified as a viable
strategy for dealing with diabetes-associated complications, and it has been put under
investigation by various researchers around the world. 2,4-Thiazolidinedione (TZD) and its
bio-isosteric analog 2-thioxo-4-thiazolidinone (rhodanine) have been explored as potential
inhibitors of aldose reductase to find new molecules. The current review provides a
comprehensive insight into the development and medicinal chemistry of TZD and rhodanine
derivatives as aldose reductase inhibitors during the last twenty years(2002–2021). Here, the
synthetic strategies, SAR, and binding mode ofvarious compounds, Quantitative structure
activity relationship (QSARs) are discussed with an emphasis on structural changes to the both
moieties for optimizing/designing potent target-specific inhibitors, which is expected to be
beneficial for the further design anddiscovery of newer agents for the treatment of diabetic
complications. In addition, the patents on TZDs and rhodanine derivatives as aldose reductase
inhibitors are summarized to illustrate the current status.

This study reports, 35 novel rhodanine, its bioisosteres thiazolidinedionesand is tested for EGFR inhibition.
These molecules are designed by using apharmacophore-based superimpose approach taking Gefitinib as a
core structure or reference. All the designed molecules were synthesized from 3-chloro and 4-fluoro
substituted aniline as the precursors and converted to corresponding dithiocarbamate (3a, b) by reacting
with carbon disulfide in presence of ammonia. Further, it was cyclized to rhodanine (4a, b) and subjected to
Knoevenagel condensation to find compounds
5(a-j) and 6(a-i). All the compounds are analyzed and from the NMR results, we found that Knoevenagel
condensed products are of “Z” geometrical isomers. Further, rhodanine was converted to its bioisosteric
form thiazolidinedione by reacting it with a catalytic amount of diacetoxy-iodobenzene in presence of
alcohol. All the synthesized compounds are characterized by IR, 1H NMR, 13C NMR, and Mass analysis,and
screened for their EGFR inhibition, among all the synthesized compounds, compound 5i, 6 h, 7c, and 8f
showed promising results by inhibiting EGFR at <10 nM. Further, structure-activity relationships were
established via CoMSIA studies.
A series of 35 novel rhodanine, its bioisosteres thiazolidinediones were
synthesized by taking 4-fluoro and 3-chloro aniline as a precursors 86
and different aldehydes via Knoevenagel condensation. The
synthesized compounds were subjected to In vitro EGFR assay. All the
compounds showed a comparable biological activity compared to the
standard drug. Additionally, molecular docking and CoMSIA study
were performed to support the hypothesis.
