已经制备了许多2-苯基-4 H-苯并[ b ]硫吡喃-4-酮(硫代黄酮)和相关化合物以测试其抗菌活性。还制备了黄酮衍生物以与其抗菌活性进行比较。发现羟基硫代黄酮很容易通过用氯化铝使甲氧基硫代黄酮脱甲基而制得。在抗菌活性测试中,发现甲氧基或羟基硫代黄酮没有活性。建议将硫黄酮的砜或亚砜用于抗酵母菌和霉菌的抗菌活性。这些硫代黄酮衍生物表现出低的急性毒性。

A series of 3-(substitutedMethyl)-2-phenyl-4H-l-benzothiopyran-4-ones (thioflavones) and thioflavone 1,1-dioxides was prepared to test for antimicrobialactivity and for antitumor activity. It was shown that an introduction of a substitutedmethyl group in the 3-position of thioflavone resulted in significant antimicrobialactivity against Trichophytons. 3-(Acetoxymethyl)thioflavone shows the most
number of 2-phenyl-4H-benzo[b]thiopyran-4-ones (thioflavones) and relatedcompounds have been prepared to test their antibacterialactivity. The flavone derivatives were also prepared to compare with their antibacterialactivity. It was found that hydroxythioflavones were easily prepared by demethylation of methoxythioflavones with aluminium chloride. In the test of antimicrobial activity, methoxy-
