The synthesis of a new series of 5-or 6-methyl-2-(2,4-disubstituted phenyl) benzoxazoles (4, 5) is described in order to determine their antimicrobial activities and feasible structure-activity relationships. The synthesized compounds were tested in vitro against three Gram-positive bacteria, three Gram-negative bacteria and the yeast Candida albicans, in comparison with several control drugs.

描述了一系列新的5-或6-甲基-2-(2,4-二取代苯基)苯并恶唑(4,5)的合成,以确定它们的抗菌活性和可行的构效关系。与几种对照药物相比,体外针对三种革兰氏阳性细菌,三种革兰氏阴性细菌和白色念珠菌酵母测试了合成的化合物。微生物学结果表明,合成的化合物对被测微生物具有广泛的抗菌活性。化合物4b和4c显示出对金黄色葡萄球菌的某些抗菌活性,其最小抑菌浓度(MIC)为12.5微克/毫升。此外,化合物5a显示出对铜绿假单胞菌肠杆菌的显着抗菌活性,其MIC值为25微克/ ml,即比对照药物四环素和链霉素更有效。对于针对白色念珠菌的抗霉菌活性,发现衍生物4c比其他合成的化合物更具活性,其MIC值为12.5微克/毫升,但效力比对照药物奥昔康唑和卤代普罗辛低一倍。
