A series of 2-Arylamino-3-chloro-1,4-naphthoquinones (3), 2-Amino-3-arylsulfanyl-1,4-naphthoquinones (5), 2-Arylamino-3-arylsulfanyl-1,4-naphthoquinones (6), Dihydrobenzo[f]naphtho[2,3-b][1,4]thiazepine-6,11-diones (9) (via Pictet–Spengler cyclization), Isoindoline-1,3-dione derivatives of 1,4-naphthoquinone (13), 2,2′-(1,4-Dioxo-1,4-dihydronaphthalene-2,3-diyl)bis(methylene)dibenzonitrile (14), 13-Amino-12-substituted-6H-benzo[e]naphtho [2,3-b][1,4]diazepine-6,11(12H)-diones (15–16), 2-Chloro-3-arylsulfanyl-1,4-naphthoquinones (17–18) and 3-Methyl-6H-benzo[b]phenothiazine-6,11(12H)-dione (19) were synthesized and studied for their antifungal and antibacterial activities. The results indicate that compounds 3b, 5a and 5b have potent antifungal activity. Amongst the most promising antifungal compounds, 3b showed better antifungal activity than clinically prevalent antifungal drug Fluconazole …
