the antibacterial activity of the Mannich bases derived from 4,5-disubstituted 1,2,4-triazole-3-thiones. This activity was considerably increased by an introduction of a chlorine atom to the phenyl ring. The obtained compounds were particularly active against opportunistic bacteria (Bacillus subtilis and Bacillus cereus). The antibacterial activity of some Mannich bases was similar or higher than the
我们的研究证明,C-5 取代基的化学性质显着决定了衍生自 4,5-二取代 1,2,4-三唑-3-硫酮的曼尼希碱的抗菌活性。通过在苯环中引入氯原子,该活性显着增加。获得的化合物对机会性细菌(枯草芽孢杆菌和蜡状芽孢 杆菌)特别有效。某些曼尼希碱的抗菌活性与氨苄西林、头孢呋辛等常用抗生素的抗菌活性相似或更高。
