A series of arylhydrazone derivatives bearing a rhodanine moiety have been synthesized, characterized, and evaluated as antibacterial agents. Some of these compounds showed potent antibacterial activities against several different strains of Gram-positive bacteria, including multidrug-resistant clinical isolates. Of the compounds tested, IIk and IIIk were identified as the most effective, with minimum inhibitory concentration values of 2–4 μg/mL against multidrug-resistant Gram-positive organisms, including methicillin-resistant and quinolone-resistant Staphylococcus aureus. None of the compounds exhibited any activity against the Gram-negative bacteria Escherichia coli 1356 at 64 μg/mL.
一系列含有绕丹宁基团的苯腙衍生物已被合成、表征并评估为抗菌剂。其中一些化合物显示出对多种不同革兰氏阳性菌株的强效抗菌活性,包括多药耐药的临床分离株。在测试的化合物中,IIk和IIIk被认定为最有效,对包括甲氧西林耐药和喹诺酮耐药的金黄色葡萄球菌在内的多药耐药革兰氏阳性菌的最低抑制浓度值为2-4 μg/mL。这些化合物在64 μg/mL的浓度下对革兰氏阴性菌大肠杆菌1356均未表现出任何活性。
