In this study, a series of alkyl diamine linked bivalent β-carbolines was synthesized and evaluated as antitumor agent. The results demonstrated that most compounds displayed good antiproliferative activities with IC50 value lower than 10 µM against a panel of human tumor cell lines, and compound 8 was found to be the most potent antiproliferative agent with IC50 value of 1.39, 1.96, 1.42, 1.49, 1.32, 1.96 and 1.63 µM against human breast cancer cell line (MCF-7), human adenocarcinoma cell line (769-P), human malighant melanoma cell line (A375), human ovarian cancer cell line (SK-OV-3), human colon carcinoma cell line (HCT-116), human gastric cancer cell line (BGC-823) and human esophageal squamous carcinoma cell line (Eca-109), respectively. Further investigations on mechanism of action of this class of compound demonstrated that the representative compound 8 inhibited colorectal cancer growth through inducing autophagy.
在本研究中,合成了一系列烷基二胺连接的二价β-咔啉并评估其抗肿瘤剂的作用。结果表明,大多数化合物对一组人肿瘤细胞系表现出良好的抗增殖活性,IC50值低于10μM,并且发现化合物8是最有效的抗增殖剂,IC50值分别为1.39、1.96、1.42、1.49、 1.32、1.96 和 1.63μM,针对人乳腺癌细胞系 (MCF-7)、人腺癌细胞系 (769-P)、人恶性黑色素瘤细胞系 (A375)、人卵巢癌细胞系 (SK-OV-3)、分别为人结肠癌细胞系(HCT-116)、人胃癌细胞系(BGC-823)和人食管鳞癌细胞系(Eca-109)。对该类化合物作用机制的进一步研究表明,代表性化合物8通过诱导自噬抑制结直肠癌的生长。
