A new series of 1,4‐disubstituted phthalazinylpiperazine derivatives 7a–f, 12a–f and 20a–f were designed and synthesized in order to develop potent and selective antitumor agents. The target compounds were screened for their cytotoxic activities against A549, HT‐29 and MDA‐MB‐231 cancer cell lines in vitro. Among them, compounds 7a–f exhibited excellent selectivity for MDA‐MB‐231 with IC50 values ranging
设计并合成了一系列新的 1,4-二取代酞嗪基哌嗪衍生物 7a-f、12a-f 和 20a-f,以开发有效和选择性的抗肿瘤剂。在体外筛选了目标化合物对 A549、HT-29 和 MDA-MB-231 癌细胞系的细胞毒活性。其中,化合物 7a-f 对 MDA-MB-231 表现出优异的选择性,IC50 值范围为 0.013 µM 至 0.079 µM。最有希望的化合物 7e(IC50 = 2.19 µM、2.19 µM、0.013 µM)的活性分别是 vatalanib(IC50 = 20.27 µM、21.96 µM、63.90 µM)的 9.3、10 和 4.9 × 103 倍。
