Abstract:
In the present study, a novel series of N ‐((substituted)carbamothioyl)‐2,4‐dimethylquinoline‐3‐carboxamide ( 7a ‐ 7s ) was synthesized by microwave‐assisted method. Structure of these derivatives was examined by spectroscopic techniques such as 1 H NMR, 13 C NMR, FT‐IR, and ESI‐MS. Further, the novel synthesized compounds were evaluated for their in‐vitro biological activities against antibacterial, antifungal, antimalarial, and antituberculosis activity as well as for in‐silico study. The antimalarial results demonstrated that compounds 7c and 7q (0.02 μg/mL) have notable potency against Plasmodium falciparum compared with chloroquine (0.02 μg/mL); compounds 7l (0.10 μg/mL), 7e , 7s (0.19 μg/mL), 7b , 7p (0.15 μg/mL), 7a , 7f , and 7f (0.25 μg/mL) also exhibited good activity against P. falciparum compared with quinine (0.26 μg/mL) as standard drug. Docking was performed on PFDHFR‐TS , given the effect of compounds against the P. falciparum strain was excellent in comparison with standard drug. Molecular docking suggested that compounds 7b , 7i and 7c , 7e , and 7l closely bind with the active site of protein 3JSU and 4DP3 , respectively, and compared with biological activity. We have also carried out molecular dynamics simulation on the best dock compound 7e complex with PDB: 3JSU to check the stability of docked complex and their molecular interaction. The calculated ADME‐Tox descriptors for the synthesized compounds validated good pharmacokinetics properties, suggesting that these compounds could be used as hit for the development of the new active agents.
