title: Anti-HIV agents. V. Synthesis, structure and in vitro anti-HIV activity of novel 1H,3H-naphtho[2',3':4,5]imidazo[1,2-c]thiazoles.
abstract: A series of 1H,3H-naphtho[2',3':4,5]imidazo[1,2-c]thiazoles, TBZ analogues, was prepared in order to explore the influence on anti-HIV activity of the spatial requirements of the hydrophobic moiety fused to imidazothiazole system. In spite of a butterfly-like conformation evidenced by X-ray analysis of compound 4g, the results of in vitro screening suggest that the replacement of the benzene fused ring by the naphthyl moiety negatively influences the activity of analogous thiazolobenzimidazole derivatives, some of which are potent non-nucleoside HIV-1 RT inhibitors.
