Twenty-one new chalcones 9a-m (excluding 9e, 9j and 9l) and 10a-m (excluding 10j and 10l), containing nucleobases
were synthesized from 2'-hydroxyacetophenone (1) by the reactions including chloromethylation, nucleophilic
substitution with thymine and uracil, and Claisen-Schmidt reactions. These new chalcones were evaluated for in vitro cytotoxicity
against five human cancer cell lines: SK-LU-1, Hep-G2, MCF7, SW480 and P388. The results showed that
most of the tested chalcones exhibited inhibitory activity against five cancer cell lines except 10h, and 10i. Among the
synthesized chalcones, compound 10c exhibited most potent cytotoxicity against MCF-7, SK-LU-1, SW480, HepG2 and
P388 with IC50 values of 4.42, 4.81, 5.27, 3.67 and 4.11μg/mL, respectively.
21 个新查耳酮 9a-m(不包括 9e、9j 和 9l)和 10a-m(不包括 10j 和 10l),含有核碱基
由2'-羟基苯乙酮(1)通过氯甲基化、亲核化等反应合成
胸腺嘧啶和尿嘧啶取代,以及克莱森-施密特反应。对这些新查耳酮进行了体外细胞毒性评估
针对五种人类癌细胞系:SK-LU-1、Hep-G2、MCF7、SW480 和 P388。结果表明
大多数测试的查耳酮对除 10h 和 10i 之外的五种癌细胞系均表现出抑制活性。其中
合成的查耳酮中,化合物 10c 对 MCF-7、SK-LU-1、SW480、HepG2 和
P388 的 IC50 值分别为 4.42、4.81、5.27、3.67 和 4.11μg/mL。
