This study presents the synthesis of 14 new 1,4-disubstituted piperazine derivatives from allyl bromides of Baylis–Hillman adduct and 4,4-disubstituted benzhydryl piperazines. All the synthesized compounds were further screened for in vitro ACE inhibitor and antimicrobial activities. Among the synthesized piperazine derivatives, compound 12h showed moderate ACE inhibitor activity as compared to the
这项研究提出了由Baylis-Hillman加合物的烯丙基溴和4,4-二取代的苯甲基哌嗪合成14种新的1,4-二取代的哌嗪衍生物。进一步筛选所有合成的化合物的体外ACE抑制剂和抗菌活性。在合成的哌嗪衍生物中,与标准的血管紧张素转化酶抑制剂(Sigma)相比,化合物12h具有中等的ACE抑制剂活性。还确定了化合物12h和ACE抑制剂标准物的酶抑制动力学数据(K m,K i和V max值)。类似地,针对不同细菌菌株筛选所有化合物。化合物图12a,12b,12d,12h和12i显示出对各种测试的细菌菌株的优异至中等的活性。化合物12B和12I显示对抗菌活性的广谱铜绿假单胞菌,金黄色葡萄球菌,链球菌 金黄色葡萄球菌MLS 16 ,大肠杆菌,枯草芽孢杆菌和克雷伯氏菌,而化合物12A,12D和12I显示出期望的活性针对P. 铜绿假单胞菌(MIC的值8.96μM),S. 黄色葡萄球菌(42.2μM的MIC值)和S
