本發明關於藥理活性經取代之(吖)吲哚化合物,或其醫藥上可接受之鹽、生物活性代謝物、前藥、消旋物、鏡像異構物、非鏡像異構物、溶劑合物及水合物,以及含有彼等之醫藥組成物及彼等作為哺乳動物個體中的α7菸鹼乙醯膽鹼受體活性之調節劑的用途。The present invention relates to substituted (acridine) indole compounds with pharmacological activity, or their pharmaceutically acceptable salts, biologically active metabolites, prodrugs, racemates, enantiomers, diastereomers, solvates And hydrates, as well as their pharmaceutical compositions and their use as modulators of the activity of α7 nicotinic acetylcholine receptors in mammalian individuals.

乙醯膽鹼(ACh)係藉由結合至膽鹼能受體而在哺乳動物中樞神經系統(CNS)中發揮其作為神經傳遞物的功能。哺乳動物CNS含有二種主要類型的ACh受體:分別基於毒蕈鹼及菸鹼之促效活性的毒蕈鹼(mAChR)及菸鹼(nAChR)受體。菸鹼乙醯膽鹼受體為由五種次單元所組成之配體閘控離子通道(Purves等人之Neuroscience 4th ed. (2008) 122-126)。菸鹼受體之次單元屬於多基因家族且基於彼等的胺基酸序列而分成二組;一組含有α次單元,及另一組含有β次單元。不同的次單元組合之五聚體組合體導致很多具有各種藥理學性質的受體亞型。最廣泛地表現之亞型的組合體包括肌肉型((α1)2 β1 δε)、神經節型((α3)2 (β4)3 )及CNS型(α4)2 (β2)3 或(α7)5 ) nAChR 亞型(Le Novère N等人之Journal of Molecular Evolution 40 (1995) 155-172)。當單獨表現時,已顯示出α7次單元形成功能性受體,且因此推測形成同源寡聚型(homooligomeric)五聚體受體。 nAChR離子通道之活化主要係藉由在習知的促效劑結合位點上結合配體來控制,但亦藉由負向或正向異位性調節劑(NAM和PAM)來調節。nAChR之異位性過渡態模式至少包含靜止狀態、活化狀態及「脫敏化(desensitised)」封閉通道狀態,藉此過程使受體對促效劑變得不敏感。不同的nAChR配體可穩定受體之構形狀態,使彼等優先與其結合。例如,促效劑ACh及(-)-菸鹼分別穩定活化及脫敏化狀態。菸鹼受體之活性變化已與許多疾病有關。已假定菸鹼受體的減少會介導疾病中所見之認知缺失,諸如阿茲海默氏症(Alzheimer’s disease)和思覺失調症。來自菸草之菸鹼效應亦經菸鹼受體介導,且因為菸鹼效應係穩定呈脫敏化狀態之受體,所以增加的菸鹼受體活性可能降低對吸菸的慾望。 然而,以在與ACh相同的位點上起作用之菸鹼受體促效劑治療有問題,因為ACh不僅活化,且亦通過過程阻滯受體活性,其包括脫敏及非競爭性阻滯。此外,延長活化似乎會誘發持久的去活化。因此,可預期ACh之促效劑在長期投予(chronic administration)時失去有效性。 雖然α7 nAChR係以其與其他亞型相比而快速的活化動力學及對Ca2+ 之高滲透性為特徵(Delbono等人之J. Pharmacol. Exp. Ther .280 (1997) 428-438),但其亦在暴露於正構位點(orthosteric site)上的促效劑後展現快速脫敏(Castro等人之Neurosci. Lett. 164 (1993) 137-140;Couturier等人之Neuron 5 (1990) 847-856)。儘管近年來已進行各種α7-選擇性促效劑及部分促效劑的開發,但由於此受體在促效劑活化後阻滯(脫敏)而使彼等臨床功效經證明為次優的。此問題可藉由以PAM治療,增強由內源性促效劑介導之α7 nAChR活化來克服。α7 nAChR之正向調節已在各種臨床前模式中顯示出具有認知效益(Thomsen等人之Curr Pharm Des 16 (2010) 323-343;Lendvai等人之Brain Res Bull 93 (2013) 86-96)。Acetylcholine (ACh) exerts its function as a neurotransmitter in the mammalian central nervous system (CNS) by binding to cholinergic receptors. Mammalian CNS contains two main types of ACh receptors: muscarinic (mAChR) and nicotinic (nAChR) receptors based on the agonistic activity of muscarinic and nicotine, respectively. The nicotinic acetylcholine receptor is a ligand-gated ion channel composed of five subunits (Purves et al. Neuroscience 4th ed. (2008) 122-126). The subunits of nicotinic receptors belong to the multigene family and are divided into two groups based on their amino acid sequences; one group contains α subunits, and the other group contains β subunits. The pentamer combinations of different subunit combinations result in many receptor subtypes with various pharmacological properties. The most widely expressed subtypes include muscle type ((α1) 2 β 1 δε), ganglion type ((α3) 2 (β4) 3 ) and CNS type (α4) 2 (β2) 3 or (α7 ) 5 ) nAChR subtype (Le Novère N et al. Journal of Molecular Evolution 40 (1995) 155-172). When presented alone, it has been shown that the α7 subunit forms a functional receptor, and therefore it is speculated to form a homooligomeric pentameric receptor. The activation of nAChR ion channels is mainly controlled by binding ligands at the binding sites of conventional agonists, but also by negative or positive ectopic regulators (NAM and PAM). The ectopic transition state pattern of nAChR includes at least a resting state, an activated state and a "desensitised" closed channel state, by which the receptor becomes insensitive to agonists. Different nAChR ligands can stabilize the configuration state of receptors, so that they preferentially bind to them. For example, the agonists ACh and (-)-nicotine stabilize the activation and desensitization states, respectively. Changes in the activity of nicotinic receptors have been associated with many diseases. It has been hypothesized that the reduction of nicotinic receptors will mediate the cognitive deficits seen in diseases such as Alzheimer's disease and mental disorders. The nicotinic effect from tobacco is also mediated by nicotinic receptors, and because nicotinic effects are stable receptors in a desensitized state, increased nicotinic receptor activity may reduce the desire to smoke. However, treatment with nicotinic receptor agonists that act on the same site as ACh is problematic because ACh not only activates but also blocks receptor activity through processes, which include desensitization and non-competitive blockade . In addition, prolonged activation seems to induce lasting deactivation. Therefore, it is expected that the agonist of ACh will lose its effectiveness when administered chronically. Although α7 nAChR is characterized by its rapid activation kinetics and high permeability to Ca 2+ compared to other subtypes (Delbono et al. J. Pharmacol. Exp. Ther . 280 (1997) 428-438) , But it also exhibits rapid desensitization after exposure to agonists on the orthosteric site (Castro et al. Neurosci. Lett. 164 (1993) 137-140; Couturier et al. Neuron 5 (1990 ) 847-856). Although various α7-selective agonists and some agonists have been developed in recent years, their clinical efficacy has proven to be sub-optimal due to their blockade (desensitization) after activation of the agonist . This problem can be overcome by treatment with PAM to enhance activation of α7 nAChR mediated by endogenous agonists. The positive regulation of α7 nAChR has been shown to have cognitive benefits in various preclinical models (Thomsen et al. Curr Pharm Des 16 (2010) 323-343; Lendvai et al. Brain Res Bull 93 (2013) 86-96).

The final DMSO concentration for all treatments was 1%. To achieve this concentration, a series of DMSO stock solutions were prepared from all test compounds. These stock solutions were stored at 0°C and further diluted in assay buffer immediately before measurement to obtain the desired final concentration. The agonist and PAM concentration response studies were conducted in the presence of saturated concentrations of PAM (mainly PNU-120596, 5 µM) and agonist (mainly PNU-282987, 1 µM). The results are expressed in terms of ΔF/F using SoftMax Pro software (Molecular Devices), where F is the stationary fluorescence before application of the agonist, and ΔF is the increase in fluorescence at the given time (ΔF = maximum after stimulation (Fluorescence intensity value minus the average fluorescence intensity value before stimulation). In all experiments, all treatments were measured in parallel in multiple wells and analyzed using average ΔF/F values. Table 16 is shown in [Ca2+ ]i PAM EC in the verification method50 value:

In vivo pharmacology ( Position recognition test ) Animals: Male NMRI mice (Toxicoop, Hungary) Substance: Dissolve scopolamine in saline and administer i.p. at a dose of 1 mg/kg. The test compound was administered 30 minutes before the acquisition trial (T1) and the scopolamine was administered in a volume of 0.1 ml/10 g after the acquisition trial. Procedure: The task is performed in a transparent plastic glass Y-shaped maze (each arm has a length of 40 cm, an internal width of 11 cm and a height of 30 cm). Many visual cues are placed around the arm and remain unchanged during the experiment. The test consists of two sets of tests (T1 and T2) with a time interval of 30 minutes. The mouse line was placed in the starting arm of the maze at the beginning of each experiment. In T1, one of the symmetric arms of the maze is closed (which is a novel arm in T2) and the animal is allowed to explore the maze for 5 minutes (learning period). In T2, mice can freely enter all three arms for 2 minutes (retrieval phase). Measure the time spent exploring the novel arm and familiarizing the arm during T2. The difference between the exploration time spent by the familiar arm of the labyrinth on the novel arm was evaluated by MANOVA followed by Duncan post hoc test. Table 17 shows the reversal of scopolamine-induced amnesia in the position recognition test of mice:
