With an intention to synergize the anti-bacterial activity of chalcones and rhodanine-3-acetic acid, several hybrid compounds possessing chalcone and rhodanine-3-acetic acid moieties were synthesized and tested for their anti-bacterial activity. Some compounds presented great anti-microbial activities against Gram-positive bacteria (including the multidrug-resistant clinical isolates). This class of
为了协同查尔酮和罗丹宁-3-乙酸的抗菌活性,合成了几种具有查尔酮和罗丹宁-3-乙酸部分的杂合化合物,并测试了它们的抗菌活性。一些化合物对革兰氏阳性细菌(包括耐多药临床分离株)表现出极大的抗菌活性。这类化合物对金黄色葡萄球菌具有很高的效力,其中衍生物5k的MIC为2μg/ mL,与标准药物(诺氟沙星)一样有效,而活性却不如奥沙西林。化合物5a–s不会抑制革兰氏阴性细菌大肠杆菌CCARM 1924或大肠杆菌的生长 CCARM 1356的浓度为64μg/ mL。
