Definitions
- the present invention relates to a compound of formula (I) or a pharmaceutically acceptable salt and / or solvate thereof for use in the treatment of bacterial infections.
- Bacterial infections are responsible for diseases or syndromes such as urinary tract infections, skin and soft tissue infections, sexually transmitted infections, tetanus, typhoid, tuberculosis, cholera, syphilis, salmonella, pneumonia or sepsis. Despite the large number and diversity of antibacterial agents, bacterial infections are one of the leading causes of death worldwide, especially in developing countries.
- NAD + is involved in hundreds of redox reactions in the cell, in particular at the level of the mitochondria and the Kreps cycle.
- NAD + is an essential cosubstrate for a number of non-redox enzymes (e.g. sirtuins (SIRTs), poly-ADP-rybosyl polymerases (PARPs), ADPR cyclases (ADP rybosyl cyclases like CD38 and CD73) , and mono-ADP-rybosyl transferases (MARTs) in mammals and DNA ligases and deacetylase proteins of the CobB / Sir2 family in bacteria).
- SIRTs sirtuins
- PARPs poly-ADP-rybosyl polymerases
- ADPR cyclases ADP rybosyl cyclases like CD38 and CD73
- MARTs mono-ADP-rybosyl transferases
- SIRT2 sirtuin modulates many cellular processes including carcinogenesis, the cell cycle, DNA damage, and the cellular response to infection.
- SIRT2 is relocated from the cytoplasm to the nucleus where post-translational modifications on the enzyme (dephosphorylation) induce its association with chromatin and promote the progression of the infection (2018, Cell Reports, 23, 1124-1137).
- TRPM2 transi ent receptor potential melastatin-2
- necrotic exotoxins into the cytosol of infected macrophages.
- exotoxins can have ADP-rybosyltransferase or b-NAO + glycohydrolase activities. The latter deprive host cells, in the absence of other targets, of their NAD + resources, thus triggering the activation of necroptosis mechanisms (2019, Journal of Biological Chemistry, 294 (9), 3024-3036).
- Nicotinamide mononucleotide is a nucleotide that is best known for its role as an intermediary in the biosynthesis of nicotinamide adenine dinucleotide (NAD +). Mainly known for its involvement in the biosynthesis of NAD +, this particular molecule has been shown to be pharmacologically effective in several preclinical studies.
- the aim of this invention is to provide an alternative to current treatments by providing nicotinamide mononucleotide derivatives for the treatment of bacterial infections.
- nicotinamide mononucleotide derivatives according to the invention are well tolerated and make it possible to reduce bacterial propagation.

- ciprofloxacin is also administered at an underactive dose (2 mg / kg) to mice intraperitoneally under the same conditions.
- Co-administration of ciprofloxacin and of compound IA is also carried out, under the same conditions. J.3. Bacterial load
- the bacterial load is evaluated in the blood and the lungs on day 5. Quantitative cultures on agar gel are carried out during 24 hours of incubation at 37 ° C. The count of viable bacterial colonies is expressed in Log10 CFU per mL of blood or per gram of organ.
- Figure 7 shows the bacterial load in the blood (Fig. 7A) and in the lungs (Fig. 7B), 5 days after infection with Pseudomonas aeruginosa.
- the evaluation of the pulmonary bacterial load showed an antibacterial effect of the treatment with compound LA, ciprofloxacin or a combination of ciprofloxacin and compound LA.
