A series of isatin-dihydropyrazole hybrids have been synthesized in order to assess their potential as anticancer agents. In particular, 12 compounds were evaluated for their antiproliferative activity toward A549, IGR39, U87, MDA-MB-231, MCF-7, BT474, BxPC-3, SKOV-3, and H1299 cell lines, and human foreskin fibroblasts. Four compounds exhibited interesting antiproliferative activity and were further examined to determine their EC values toward a panel of selected tumor cell lines. The best compounds were then investigated for their induced mechanism of cell death. Preliminary structure-activity relationship indicates that the presence of a substituent such as a chlorine atom or a methyl moiety in position 5 of the isatin nucleus is beneficial for the antitumor activity. proved the most promising compound within the studied series with EC values ranging from 0.01 to 0.38 μM.
为了评估一系列异吲哚酮-二氢吡唑杂化物作为抗癌剂的潜力,已合成了这些化合物。特别地,评估了12种化合物对A549、IGR39、U87、MDA-MB-231、MCF-7、BT474、BxPC-3、SKOV-3和H1299细胞系以及人包皮成纤维细胞的抗增殖活性。四种化合物表现出有趣的抗增殖活性,并进一步检测以确定它们对一组选定肿瘤细胞系的EC值。然后研究了最佳化合物的细胞死亡诱导机制。初步构效关系表明,异吲哚酮核5位存在氯原子或甲基等取代基有利于抗肿瘤活性。在所研究的系列中被证明是最有前途的化合物,其EC值范围为0.01至0.38μM。
