Abstract
In the pursuit of novel antidiabetic agents, a series of isatin-thiazole derivatives (7a-7j) were synthesized and characterized using a range of spectroscopic techniques. The enzyme inhibitory activities of the target analogues were assessed using both in vitro and in vivo assays. The tested compounds 7a-7j demonstrated In vitro inhibitory potential against α-glucosidase, as indicated by their IC50 values ranging from 28.47 to 46.61 µg/ml as compared to standard drug acarbose IC50 value of 27.22 ± 2.30 µg/ml. Additionally, compounds 7d and 7i were chosen for in vivo evaluation of their antidiabetic efficacy in streptozotocin-induced diabetic Wistar rats. These compounds exhibited significant antidiabetic activity both in vitro and in vivo, compound 7d produces therapeutic effects compared to standard pioglitazone by decreasing glycaemia and triglyceride levels in diabetic animals. Furthermore, a molecular docking study was conducted to elucidate the binding interactions of the compounds within the α-glucosidase enzyme binding pocket (PDB ID 3A47) and stability was confirmed by dynamics simulation trajectories. Thus, from the above findings, it may demonstrate that isatin-thiazole hybrids constitute promising candidates in the pursuit of developing newer oral antidiabetic agents.

Synthesis,Antidiabetic and Antitubercular Evaluation of Quinoline-pyrazolopyrimidine hybrids and Quinoline-4-Arylamines. ChemistryOpen 2024:e202400014.

Abstract
Two libraries of quinoline-based hybrids 1-(7-chloroquinolin-4-yl)-1H-pyrazolo[3,4-d]pyrimidin-4-amine and 7-chloro-N-phenylquinolin-4-amine were synthesized and evaluated for their α-glucosidase inhibitory and antioxidant properties. Compounds with 4-methylpiperidine and para-trifluoromethoxy groups, respectively, showed the most promising α-glucosidase inhibition activity with IC50 =46.70 and 40.84 μM, compared to the reference inhibitor, acarbose (IC50 =51.73 μM). Structure-activity relationship analysis suggested that the cyclic secondary amine pendants and para-phenyl substituents account for the variable enzyme inhibition. Antioxidant profiling further revealed that compounds with an N-methylpiperazine and N-ethylpiperazine ring, respectively, have good DPPH scavenging abilities with IC50 =0.18, 0.58 and 0.93 mM, as compared to ascorbic acid (IC50 =0.05 mM), while the best DPPH scavenger is NO2 -substituted compound (IC50 =0.08 mM). Also, compound with N-(2-hydroxyethyl)piperazine moiety emerged as the best NO radical scavenger with IC50 =0.28 mM. Molecular docking studies showed that the present compounds are orthosteric inhibitors with their quinoline, pyrimidine, and 4-amino units as crucial pharmacophores furnishing α-glucosidase binding at the catalytic site. Taken together, these compounds exhibit dual potentials; i. e., potent α-glucosidase inhibitors and excellent free radical scavengers. Hence, they may serve as structural templates in the search for agents to manage Type 2 diabetes mellitus. Finally, in preliminary assays investigating the anti-tubercular potential of these compounds, two pyrazolopyrimidine series compounds and a 7-chloro-N-phenylquinolin-4-amine hybrid showed sub-10 μM whole-cell activities against Mycobacterium tuberculosis.
