synthesized and evaluated as antitumor agents against six cancer cell lines (H460, H520, HeLa, HepG-2, MCF-7, SW480 cell lines) and BEAS-2B normal cells by CCK-8 analysis. Ten derivatives showed better cytotoxic effects than the parent fangchinoline, of which 4g showed the strongest cell growth inhibitory activity with an IC50 value of 0.59 μM against A549 cells. Subsequently, the antitumor mechanism of 4g was
癌症治疗是世界上主要的公共卫生问题之一。Tetrandrine (Tet) 和 fangchinoline ( d -Tet) 是两种双苄基异喹啉生物碱,从Stephania tandra S. Moore 中提取,其抗肿瘤活性已得到证实。然而,Tet和d - Tet的有效剂量远高于阳性对照,未能达到临床标准。因此,在本研究中,作为我们之前研究和开发高效低毒抗肿瘤先导化合物的工作的延续,二十个新的 Tet 和d-通过 CCK-8 分析,设计、合成和评估了 Tet 衍生物作为针对六种癌细胞系(H460、H520、HeLa、HepG-2、MCF-7、SW480 细胞系)和 BEAS-2B 正常细胞的抗肿瘤剂。10 种衍生物显示出比亲本 fangchinoline 更好的细胞毒作用,其中4g显示出最强的细胞生长抑制活性,对 A549 细胞的 IC 50值为 0.59 μM。随后,通过流式细胞术、Hoechst
