streptomycin . In addition, compound 4b and 7c were the most active against Pseudomonas aeruginosa (MIC<25, 50 microg ml(-1)). Compound 4b was two times as active as ampicillin and streptomycin while compound 7c was active as both. The results of antimycotic activity indicated that, Compound 7c showed mild activity against Candida albicans when compared with clotrimazole (MIC<100 microg ml(-1)). In vitro HIV-1
