N-Substituted N-thioformylhydroxylamine derivatives represented by the general formula [chemical formula] (I) were synthesized and examined for antimicrobial activities. The synthesis was performed by the replacement of the carbonyl in an appropriate N-sub-stituted N-formylhydroxylamine with sulfur. These compounds were analogues of an antibiotic thioformin (II), N-methyl N-thioformylhydroxylamine, which was isolated as cupric complex (antibiotic YC-73 (III)) from a culture filtrate of Pseudomonas sp. The derivatives synthesized showed broad antimicrobial activities in vitro similar to that of the original antibiotic, particularly against gram-positive bacteria.
合成了通式 [化学式] (I) 所代表的 N-取代 N-硫代甲酰羟胺衍生物,并对其抗菌活性进行了研究。合成的方法是用硫取代适当的 N-亚代 N-甲酰基羟胺中的羰基。这些化合物是抗生素硫代甲酰甲胺(II)的类似物,N-甲基 N-硫代甲酰羟胺是从假单胞菌(Pseudomonas sp)的培养滤液中分离出来的铜络合物(抗生素 YC-73 (III))。
