Abstract

1 min read

A series of N'-nicotinoyl-3-(4'-hydroxy-3'-methylphenyl)-5-(substituted phenyl)-2-pyrazolines were synthesized by the reaction between isoniazid (INH) and chalcones and were tested for their in vitro anti-HIV activity. Among them, compound (c) showed a promising anti-HIV activity in vitro against used strains (IIIB, ROD), with IC50 of both IIIB 5.7 microM and ROD 7.0 microM.
