we described the synthesis, the antileishmanial activity and the molecular modeling and structure–activity relationship (SAR) evaluations of a series of chalcone derivatives. Among these compounds, the methoxychalcones 2h, 2i, 2j, 2k and 2l showed significant antileishmanial activity (IC50 <10 μM). Interestingly 2i (IC50 = 2.7 μM), 2j (IC50 = 3.9 μM) and 2k (IC50 = 4.6 μM) derivatives presented better
在这项工作中,我们描述了一系列查尔酮衍生物的合成,抗菌活性以及分子建模和结构-活性关系(SAR)评估。在这些化合物中,甲氧基查耳酮2h,2i,2j,2k和2l表现出显着的抗菌活性(IC 50 <10μM)。有趣的是2i(IC 50 = 2.7μM),2j(IC 50 = 3.9μM )和2k(IC 50 = 4.6μM)衍生物表现出比对照药物喷他idine(IC 50 = 6.0μM)。我们的SAR研究表明,在苯环A上进行甲氧基二邻取代的重要性以及这些分子的前沿轨道HOMO系数分布与其活性之间的关系。活性最高的化合物2h,2i,2j,2k和2l符合Lipinski的5法则,这在理论上对于良好的药物吸收和通过生物膜的渗透非常重要。2j的电位分布(IC 50 = 3.9μM,CC 50 = 216μM)表明,这种查耳酮衍生物是一种命中化合物,需要在抗衰老药物设计中进一步探索。
