Synthesis, molecular docking study, MD simulation, ADMET, and drug likeness of new thiazolo[3,2-a]pyridine-6,8-dicarbonitrile derivatives as potential anti-diabetic agents.

There are numerous uses for the pharmacological effects of thiazolo-pyridine and its derivatives. The main objective of the study was to synthesis 10 novel derivatives of thiazolo[3,2-a] pyridine-6,8-dicarbonitrile with a 22-78% yield, with a focus on their potential anti-diabetic properties. We investigated the interactions between these compounds and the enzyme α-amylase through an in silico study involving molecular docking. According to the docking analysis results, the resulting compounds had advantageous inhibitory properties. With a docking score of -7.43 kcal/mol against the target protein, compound 4e performed best. The stability root-mean-square deviation (RMSD) showed that the complex stabilizes after 25 ns and with minor perturbation at 80. The RMSF values of the ligand-protein complex indicate that the following residues have interacted with compound 4e during the MD simulation: Trp58, Trp59, Tyr62, Gln63, His101, Val107, lle148, Asn152, Leu162, Thr163, Gly164, Leu165, Asp197, Ala198, Asp 236, Leu237, His299, Asp300, and His305. Moreover, the pharmacokinetic and drug-like properties of the synthesized derivatives of 2-arylamino-dihydroindeno[1,2-b] pyrrol-4(1H)-one suggest that they have the potential to be effective inhibitors of α-amylase and should be considered for further research. Nevertheless, it is crucial to ascertain the in vivo and in vitro effectiveness of these compounds through biochemical and structural investigations.
