antibacterial and antifungal activities against E. coli, S. aureus, MRSA (methicillin-resistant S. aureus), MRSE (methicillin-resistant S. epidermidis), S. faecalis and C. albicans, C. krusei. The results showed that while all diamidines are inactive, the compounds having monoamidinobenzimidazoles at the C-6 position of the 2-phenyl-4H-1-benzopyran-4-one have potent antibacterial activities, particularly, against
合成了一系列在不同位置带有单或二mid基二苯并咪唑类的黄酮和甲基-4H-1-苯并吡喃-4-酮,并评估了其对大肠杆菌,金黄色葡萄球菌,MRSA(耐甲氧西林的金黄色葡萄球菌)的抗菌和抗真菌活性, MRSE(耐甲氧西林的表皮葡萄球菌),粪链球菌和白色念珠菌,克鲁斯氏菌。结果表明,尽管所有的二am都是不活泼的,但是在2-苯基-4H-1-苯并吡喃-4-酮的C-6位具有单ami基苯并咪唑的化合物具有有效的抗菌活性,特别是对革兰氏阳性细菌。化合物23和22表现出最好的抑制活性,其对金黄色葡萄球菌,MRSA,MRSE的MIC值为1.56μg/ ml,对白色念珠菌的MIC值为3.12μg/ ml。
