Synthesis, biological evaluation, and In silico molecular docking of N‐(4‐(4‐substitutedphenyl)‐6‐(substituted aryl) pyrimidin‐2‐yl)‐2‐(2‐isonicotinoyl hydrazinyl) acetamide

Abstract

Isonicotinohydrazide is the first‐line medication in the prevention and treatment of tuberculosis. Antitubercular, antibacterial, antifungal, antiviral, anti‐inflammatory, antimalarial activity, anticancer, antineoplastic activity, and anti‐HIV activity are all demonstrated by drugs with a pyrimidine ring. The current study focuses on the synthesis of N‐(4‐(substituted‐phenyl)‐6‐(substituted‐aryl) pyrimidin‐2‐yl)‐2‐(2‐isonicotinoylhydrazinyl) acetamide from isonicotinohydrazide. Newly synthesized compounds were characterized by spectral studies (IR, 1H‐NMR, 13C‐NMR, and mass spectroscopy). They were screened for their antituberculosis, antimalarial, and antiprotozoal activities and compared with standard drugs. Molecular docking of isonicotinohydrazide‐bearing pyrimidine motifs was also done for some of the active compounds.
