Synthesis and evaluation of novel 1,4-naphthoquinone derivatives as antiviral, antifungal and anticancer agents

The synthesis, antiviral, antifungal and anticancer activities of 4– 10 is described. The synthesis and evaluation of some 2-substituted-1,4-naphthoquinones 2, S-(1,4-naphthoquinon-2-yl)-mercaptoalkanoic acid amides 4, related benzoquinone and naphthoquinone derivatives 6– 9 and 2,3-disubstituted 1,4-naphthoquinones 10– 11 were carried out. The antifungal, antibacterial, antiviral and anticancer activities were determined by using the standard assay. The results show that compounds 2b and 10a showed in vitro antiviral activity against Inflenza-A Virus and Herpes Simplex Virus and possess pronounced antifungal profile whereas 4a showed anticancer activites against Lymphoid Leukaemia P 388.
