A series of novel diaziridinyl quinone isoxazole hybrids (9a-9j) were synthesized starting from 2, 5-dimethoxy acetophenone 1 via Claisen reaction, cyclisation, alkoxy carbonylation, hydrolysis, oxidation and aziridine insertion. All the compounds were screened for antimicrobial, anti-biofilm and cytotoxic activities. Among the screened compounds, the compound 9h showed good antibacterial and anti-biofilm
通过克莱森反应,环化,烷氧基羰基化,水解,氧化和氮丙啶插入,从2,5-二甲氧基苯乙酮1出发,合成了一系列新型的二叠氮基醌醌异恶唑杂化物(9a - 9j)。筛选所有化合物的抗微生物,抗生物膜和细胞毒性活性。在筛选出的化合物中,化合物9h表现出良好的抗菌和抗生物膜活性,相对于MIC,MIC值分别为3.9、3.9、3.9和7.8μg/ mL,IC 50值分别为1.9、2.5、2.8和5.1μM。金黄色葡萄球菌MTCC 96,金黄色葡萄球菌MLS-16 MTCC 2940,枯草芽孢杆菌MTCC 121和植物克雷伯氏菌MTCC 530,并且还显示出对白色念珠菌MTCC 227,白色念珠菌MTCC 854和库氏假丝酵母MTCC 3020与标准咪康唑等效的有效抗真菌活性(MIC值7.8μg/ mL)。所有合成的化合物均显示出对A549和PC3细胞系的有希望的细胞毒性(IC 50值介于1-4μM之间)。化合物9b和9j显示出0
