Derivatives of isatin have been reported to possess cytotoxic effects against different human carcinoma cell lines. A series of new isatin-linked chalcones was synthesized starting from isatin. Most of the newly synthesized compounds were screened for their in vitro anticancer activity against human breast (MCF-7), liver (HepG-2), and colon (HCT-116) cancer cell lines. All the tested compounds exhibited antitumor activity, with IC50 ranging from 2.88 to 62.88 μM in comparison to the reference drug used in this study, Imatinib. Compounds 2–5 were the most active, with IC50 ranging from 2.88 to 18.12 μM for the three cell lines, while compound 7b also showed moderate activity against HepG-2, MCF-7 and HCT-116 with IC50 13.95, 31.66 and 11.78 μM, respectively. Furthermore, compound 7d showed high activity against HepG-2 cells with IC50 12.84 μM. Compound 4 was shown to be the most potent against both HepG-2 and HCT-116 cell lines, while compound 2 is the most potent against MCF-7. The compounds were also screened for their cytotoxic activity against normal breast cell line MCF-12A, and were found to possess mild cytotoxicity. A docking study was performed for the most active compounds in this study, 2–5, inside the active site of CDK2. All the docked compounds have shown favorable binding interactions and energy scores. Compound 4 has proved to be the best in binding interactions and energy score. These findings may explain the cytotoxic activity of the target compounds. A novel series of isatin-linked chalcones was synthesized. The target compounds were evaluated for their cytotoxic activity towards human breast (MCF-7), liver (HepG-2), colon (HCT-116) cancer cell lines and (MCF-12A) normal breast cell line.
已报告异靛蓝的衍生物对不同人类癌细胞系具有细胞毒性作用。以异靛蓝为起始材料合成了一系列新的异靛蓝连接查尔酮。大多数新合成的化合物在体外筛选了其对人类乳腺癌(MCF-7)、肝癌(HepG-2)和结肠癌(HCT-116)细胞系的抗癌活性。所有测试的化合物均表现出抗肿瘤活性,其IC50在2.88至62.88 μM之间,相较于本研究使用的对照药物伊马替尼。化合物2-5表现出最高活性,三种细胞系的IC50范围在2.88至18.12 μM之间,而化合物7b对HepG-2、MCF-7和HCT-116也显示出中等活性,IC50分别为13.95、31.66和11.78 μM。此外,化合物7d对HepG-2细胞表现出较高活性,IC50为12.84 μM。化合物4对HepG-2和HCT-116细胞系显示出最强的活性,而化合物2对MCF-7表现出最强活性。这些化合物还被筛选出对正常乳腺细胞系MCF-12A的细胞毒性活性,发现其具有轻微的细胞毒性。对本研究中最活跃的化合物2-5在CDK2活性位点进行了对接研究。所有对接的化合物均显示出良好的结合相互作用和能量评分。化合物4在结合相互作用和能量评分方面表现最佳。这些发现可能解释了目标化合物的细胞毒性作用。合成了一系列新型的异靛蓝连接查尔酮,评估了目标化合物对人类乳腺癌(MCF-7)、肝癌(HepG-2)、结肠癌(HCT-116)细胞系及正常乳腺细胞系(MCF-12A)的细胞毒性活性。
