clinical applications. In this article, two types of dicarbonyl curcumin analogues with improved stability were designed through the calculation of molecular stability by density functional theory. Twenty compounds were synthesised, and their anti-tumour activity was screened. A plurality of analogues had significantly stronger activity than curcumin. In particular, compound B2 ((2E,2′E)-3,3′-(1,4-
摘要
姜黄素是一种具有广泛抗肿瘤活性的天然药物。然而,由于
β-二酮部分,
姜黄素表现出较差的稳定性和药代动力学,极大地限制了其临床应用。在本文中,通过密度泛函理论计算分子稳定性,设计了两种稳定性得到改善的二羰基
姜黄素类似物。合成了二十种化合物,并筛选了它们的抗肿瘤活性。多种类似物的活性明显强于
姜黄素。特别是化合物 B2 ((2E,2'E)-3,3'-(1,4-phenylene)bis(1-(2-chlorophenyl)prop-2-en-1-one)) 表现出优异的
抗体内和体外肺癌活性. 此外,B2可以上调肺癌细胞中活性氧的
水平,进而激活内质网应激,导致细胞凋亡和细胞焦亡。总之,
姜黄素类似物 B2 有望成为肺癌治疗的新候选药物,具有改善的
化学和
生物学特性。
