以异长叶烷酮为起始物,经羟醛缩合、环化等手段,合成了12种异长叶烷基二氢嘧啶硫酮类衍生物,通过1H NMR、13C NMR及高分辨质谱(HRMS)对其结构进行了表征,通过X射线衍射分析测定了化合物3e的晶体结构.探索了这些衍生物对人乳腺癌细胞(MDA-MB-231)、人宫颈癌细胞(HeLa)、人肝癌细胞(HepG-2)等三种癌细胞和一种正常细胞即小鼠巨噬细胞(RAW-264.7)的体外抗增殖活性.结果表明,这12种化合物显示出较好的抗肿瘤活性,其IC50值在3.12~44.28 μmol/L范围内.其中,化合物3j对MDA-MB-231细胞表现出最强的抗肿瘤活性(IC50=3.12 μmol/L),化合物3g对HeLa细胞表现出最强的抗肿瘤活性(IC50=4.04 μmol/L),化合物3k对HepG-2细胞表现出最强的抗肿瘤活性(IC50=5.43 μmol/L).此外,化合物3j将MDA-MB-231细胞阻滞在G0/G1期,并以剂量依赖的方式诱导MDA-MB-231细胞的早期凋亡.

In this work, twelve dihydropyrimidinethione derivatives have been synthesized from isolongifolanone by aldol and cyclization reactions. The chemical structures were characterized by 1H NMR, 13C NMR and high resolution mass spectrometry (HRMS), and the structure of compound 3e was determined by X-ray single crystal diffraction. Their in vitro cytotoxicity against three cancer cell lines breast (MDA-MB-231), cervix (HeLa), liver (HepG-2) and one normal cell line mouse macrophages (Raw-264.7) were investigated. It was shown that these 12 compounds had good antitumor activity with IC50 values of 3.12~44.28 μmol/L. Among them, compounds 3j, 3g, and 3k had the best antitumor activity against MDA-MB-231 cells (IC50=3.12 μmol/L), HeLa cells (IC50=4.04 μmol/L) and HepG-2 cells (IC50=5.43 μmol/L), respectively. In addition, compound 3j arrested the cells in the G0/G1 phase of the MDA-MB-231 cell cycle and induced the early apoptosis of MDA-MB-231 cells in a dose-dependent manner.
