the compounds screened, 3a–3e showed the most potent biological activity against tested bacteria and fungi. Compounds 3a–3e displayed higher cytotoxicity than curcumin. The curcumin derivatives were also evaluated for in vivo anti-inflammatory activity. In contrast, the compounds 6a–6e and 7a–7e showed dramatically decrease in biological activity.
五个系列与磺酰胺姜黄素衍生物的3A-3E,图4A-4E,5A-5E,6A-6E和图7A-7E已经合成并评价的体外抗菌活性针对选定的医学上重要的革兰氏- (+)和革兰氏- ( - )细菌种类 金黄色葡萄球菌,蜡状芽孢杆菌,伤寒沙门氏菌,铜绿假单胞菌和大肠杆菌,以及针对几种病原真菌的抗真菌活性。黑曲霉,黄曲霉,绿色木霉和弯孢弯孢菌。通过测量针对人类细胞系HeLa,Hep G-2,QG-56和HCT-116的IC 50值来确定细胞毒性。在筛选出的化合物中,3a-3e对被测细菌和真菌表现出最强的生物活性。化合物3a-3e显示出比姜黄素更高的细胞毒性。还评估了姜黄素衍生物的体内抗炎活性。相反,化合物6a-6e和7a-7e的生物活性显着下降。
