A series of thieno[2,3-b]thiophene moiety-containing bis-cyanopyrazoles 5a–c, bis-aminopyrazole 9 and bis-pyridazine derivatives 11 were synthesized and evaluated in vitro for their antimicrobial potential. The antimicrobial activity of some selected products was evaluated and showed good results. 5,5'-(3,4-Dimethylthieno[2,3-b]thiophene-2,5-diyl)bis(3-acetyl-1-(4-chlorophenyl)-1H-pyrazole-4-carbonitrile)
合成了一系列含有噻吩并 [2,3-b] 噻吩部分的双氰基吡唑 5a-c、双氨基吡唑 9 和双哒嗪衍生物 11,并在体外评估了它们的抗菌潜力。对一些选定产品的抗菌活性进行了评估,并显示出良好的效果。5,5'-(3,4-二甲基噻吩并[2,3-b]噻吩-2,5-二基)双(3-乙酰-1-(4-氯苯基)-1H-吡唑-4-甲腈)(5d ) 被发现比标准药物两性霉素 B 对抗白地霉更有效,与两性霉素 Bagainst Syncephalastrum racemosum 等效。此外,发现它与标准药物青霉素 G 对金黄色葡萄球菌具有同等效力。此外,它比标准药物链霉素更有效地对抗铜绿假单胞菌和大肠杆菌。
