Abstract

A series of hybrid novel chloro (1a-9a) and dichloro (10b-18b) phenylthiazolyl-s-triazine were synthesized and subsequently subjected to their antibacterial activity against three gram positive viz. Lactobacillus casei (NCIM-2651); Bacillus cereus (NCIM-2458); Staphylococcus aureus (NCIM-2120) and three gram negative viz Salmonella typhimurium (NCIM-2501); Escherichia coli (NCIM-2065); Klebsiella aerogenes (NCIM-2098). The SAR studies around the lead compound revealed that introduction of electron withdrawing groups and amino (-NH-) and mercapto (-S-) linker bridge seemed more promising towards antibacterial activity. Moreover, the virtual Molinspiration screenings are in compliance with Ghose's rule.

摘要

一系列混合新型氯(1a-9a)和二氯(10b-18b)苯基噻唑基-s-三嗪被合成,并随后对其针对三种革兰氏阳性菌(即乳杆菌属(NCIM-2651);蜡状芽孢杆菌(NCIM-2458);金黄色葡萄球菌(NCIM-2120))和三种革兰氏阴性菌(即鼠伤寒沙门氏菌(NCIM-2501);大肠杆菌(NCIM-2065);产气肠杆菌(NCIM-2098))的抗菌活性进行了测试。对先导化合物进行的 SAR 研究表明,引入吸电子基团和氨基(-NH-)和巯基(-S-)连接桥似乎更有希望提高抗菌活性。此外,虚拟 Molinspiration 筛选符合 Ghose 规则。
