Fangchinoline, a bisbenzylisoquinoline alkaloid extracted from Stephania tetrandra S. Moore, is known to exert anti-cancer activity. A series of new fangchinoline derivatives have been synthesized and evaluated for their anti-cancer activity. In cell viability assay, these fangchinoline derivatives displayed higher proliferation inhibitory activity on leukemia and breast cancer cell lines than the
防己胆碱是从Stephania tetrandra S. Moore提取的双苄基异喹啉生物碱,具有抗癌活性。已经合成了一系列新的防己诺林碱衍生物,并对其抗癌活性进行了评估。在细胞活力测定中,这些防己诺林碱衍生物对白血病和乳腺癌细胞系的抑制增殖活性高于亲本化合物。其中,3e通过诱导G0 / G1细胞周期停滞和凋亡而对白血病细胞HEL表现出最强的细胞生长抑制活性,呈剂量和时间依赖性。用3e处理HEL细胞还导致MAPK和PI3K / AKT途径的显着抑制以及c-MYC下调,这可能是诱导凋亡和细胞周期停滞的原因。在对接分析中,3e和Akt1之间的高亲和力相互作用是该化合物抑制激酶的主要原因。该衍生物化合物可用作治疗白血病的有效抗癌剂。
