Two series of compounds namely, dihydroindeno and indeno [1,2-e] [1,2,4]triazolo [3,4-b] [1,3,4]thiadizines (9a–l & 11a-l) were synthesized by cyclocondensation between α-bromoindanones (7a–b) or/and α,α-dibromoindanones (8a–b) and various 3-alkyl/aryl-4-amino-5-mercapto-1,2,4-s-triazoles (3a–f) in methanol with an aim to explore their effect on in vitro growth of microorganism causing microbial infection
合成了两个系列的化合物,即二氢茚并茚并[1,2-e] [1,2,4]三唑并[3,4-b] [1,3,4]噻二嗪(9a-1和11a-1)通过α-溴吲哚酮(7a–b)或/和α,α-二溴吲哚酮(8a–b)与各种3-烷基/芳基-4-氨基-5-氨基巯基-1,2,4-s-三唑类化合物(3a-f)在甲醇中,旨在探讨它们对引起微生物感染的微生物体外生长的影响。对金黄色葡萄球菌,枯草芽孢杆菌,大肠杆菌,铜绿假单胞菌的四种菌株进行了体外抗菌活性和对三种真菌菌株,即黑曲霉,黄曲霉,青霉菌的抗真菌活性。在所有筛选出活性的化合物中,某些化合物的抗菌和抗真菌活性要比市售抗生素高得多。
