Several five-membered heterocycles having a phenylazo substituent, 3-phenylazotetronic acids (2a-n), 3-phenylazotetramic acids (4a-i), 4-phenylazo-5-isoxazolinones (6a-g, 8a-f) and 5-phenylazo-4-thiazolidinones (10a-f, 12a-e), were synthesized and tested for antimicrobial activities. Tetronic acid and tetramic acid derivatives (2 and 4) inhibited the growth of gram-positive bacteria. 5-Isoxazolinone and 4-thiazolidinone derivatives (8 and 10) showed inhibitory activities against fungi as well as bacteria.
几种含有苯偶氮取代基的五元杂环化合物,即3-苯偶氮四嗪酸(2a-n)、3-苯偶氮四胺酸(4a-i)、4-苯偶氮-5-异恶唉酮(6a-g, 8a-f)和5-苯偶氮-4-噻唑烷酮(10a-f, 12a-e),被合成并测试了它们的抗菌活性。四嗪酸和四胺酸衍生物(2和4)抑制了革兰氏阳性细菌的生长。5-异恶唉酮和4-噻唑烷酮衍生物(8和10)不仅对细菌,而且对真菌也显示出抑制活性。
