cytotoxic activity against the human cell lines HCT-116 (Human colon carcinoma), IGROV-1 and OVCAR-3 (human ovarian carcinoma). It has been found that the derivatives 25, 37 and 45 were the most actives against HCT-116 (IC50 = 8.0, 9.0 and 9.0 μM, respectively) and against IGROV-1 (IC50 = 2.4, 5.0 and 6.0 μM, respectively). The derivatives 14 and 21 exhibited the higher anti-inflammatoryactivity at 100 μM
按照克莱森-施密特的方法,一步合成了一系列新的3-羟基黄酮(1-46),然后进行了阿尔加-弗林-奥马达达反应(AFO)。合成的类黄酮通过1 H NMR,13 C NMR和DCI-HRMS进行表征。在体外测试所有合成的化合物对人细胞系HCT-116(人类结肠癌),IGROV-1和OVCAR-3(人类卵巢癌)的15-脂氧合酶抑制作用和细胞毒活性。已经发现,衍生物25、37和45对HCT-116(分别为IC50 = 8.0、9.0和9.0μM)和对IGROV-1(分别为IC50 = 2.4、5.0和6.0μM)最具活性。衍生物14和21在100μM下表现出更高的抗炎活性,PI值分别为76.50和72.70%。分子描述是通过DFT计算完成的,药物相似性和生物活性分数。结果表明,某些化合物与Lipinski的五个规则线性相关,显示出良好的药物相似性和针对药物靶标的生物活性得分。

Abstract Photocyclisation of 3-alkoxy-6-chloro-2-(3-methylthiophen-2-yl)-4 H -chromen-4-ones in methanol with pyrex filtered UV-light lead to the formation of tetracyclic compounds through intramolecular γ-hydrogenabstraction. The methyl group on the thiophenyl ring does not interfere in the photocyclisation although it does effect the product formation.
