resistance. Here we report that luteolin, a main substance found in Flos Chrysanthemi, directly binds to and shows inhibitory activity against the Bcl-2 protein. We studied the binding mode of luteolin and its derivatives with target proteins, their structure-activity relationship, and their effect on the human leukemia cell line HL-60. The results suggest that luteolin and its derivatives with a benzyl
Bcl-2抗凋亡蛋白的过度表达与肿瘤发生密切相关,并与耐药性相关。在这里,我们报道
木犀草素(一种在Flos Chrysanthemi中发现的主要物质)与Bcl-2蛋白直接结合并表现出抑制活性。我们研究了
木犀草素及其衍
生物与靶蛋白的结合模式,它们的结构-活性关系以及它们对人白血病
细胞系HL-60的影响。结果表明
木犀草素及其带有引入B环的苄基的衍
生物是新的小分子Bcl-2蛋白
抑制剂,它们的抗肿瘤活性可能与其对Bcl-2蛋白的作用有关。
