tested Gram-positive bacteria. In addition, the anti-proliferative activity of the compounds was evaluated against prostate cancer (PC3), human colorectal cancer (HCT-116), human hepatocellular carcinoma (HePG-2), human epithelioid carcinoma (HeLa), and human breast cancer (MCF7) cell lines. The optimum anti-proliferative activity was attained by compounds 4l, 5a, 5c, and 5d.
5-(3,4-二甲氧基苯基)-1,3,4-恶二唑-2( 3H )-硫酮3与甲醛溶液和芳香伯胺或1-取代哌嗪在乙醇中于室温下反应,得到相应的产物N-曼尼希碱 3-芳氨基甲基-5-(3,4-二甲氧基苯基)-1,3,4-恶二唑-2(3 H )-硫酮4a – l或 3-[(4-取代哌嗪-1-基)甲基]-5-(3,4-二甲氧基苯基)-1,3,4-恶二唑-2(3 H )-硫酮5a – d ,分别。评估了化合物4a – l和5a – d对致病性革兰氏阳性菌、革兰氏阴性菌和酵母样致病真菌白色念珠菌的体外抑制活性。哌嗪甲基衍生物5c和5d显示出广谱抗菌活性,最低抑菌浓度 (MIC) 0.5–8 μg/mL),化合物4j 、 4l 、 5a和5b对测试的革兰氏阳性菌显示出有效的活性。此外,还评估了这些化合物对前列腺癌(PC3)、人结直肠癌(HCT-116)、人肝细胞癌(HePG-2)、人上皮样癌(HeLa)和人乳腺癌的抗增殖活性。
