gastric cancer (AGS) cell lines were evaluated using the MTT assay. The preliminary results indicated that compounds 9d and 11e-h displayed low-micromole GI50 values against all tested cell lines. In addition, compounds 10b and 10d showed wonderful antiproliferative activities towards SH-SY5Y cells with selectivity of >230-fold over K562 and AGS cells. Among them, compounds 9d, 10b, 10d and 11g with good
两个系列的N-(4-甲氧基苯基)-N-甲基-9 H-嘌呤-6-胺(9a-d和10a-h)和9个取代的苄基6-氯9 H-嘌呤(11a-h)进行了设计和合成。使用MTT分析评估了它们对人骨髓性白血病(K562),人神经母细胞瘤(SH-SY5Y)和胃癌(AGS)细胞系的抗增殖活性。初步结果表明,相对于所有测试的细胞系,化合物9d和11e-h显示出低微摩尔GI 50值。此外,化合物10b和10d对SH-SY5Y细胞显示出优异的抗增殖活性,其选择性是K562和AGS细胞的230倍以上。其中,具有良好抗肿瘤活性的化合物9d,10b,10d和11g相对于永生化小鼠海马(HT22)细胞系对肿瘤细胞系具有高选择性。此外,对AGS细胞具有亚微摩尔GI 50值的化合物9d表现出中等的微管蛋白聚合抑制活性,并且在人AGS细胞中以剂量依赖性方式诱导了G2 / M期停滞的细胞凋亡。
