Caged 4-oxa-tricyclo[4.3.1.03,7]dec-2-one structural motifs are found in Garcinia natural products that demonstrate anti-tumor activity. Gambogic acid (GA, 1), the most abundant caged Garcinia xanthones, has been reported to be a promising anti-cancer agent. To identify the essential pharmacophore for its anti-tumor activity, a series of GA analogues that address potential key structural features for
笼状的4-氧杂-三环[4.3.1.0 3,7 ] dec-2-one结构基序在藤黄天然产物中发现,具有抗肿瘤活性。据报道,笼状藤黄素含量最高的藤黄酸(GA,1)是一种很有前途的抗癌药。为了鉴定其抗肿瘤活性的基本药效团,合成了一系列解决生物活性潜在关键结构特征的GA类似物,其中化合物11a显示出与GA相当的体外抗肿瘤活性。11a的力学研究研究人员确定该化合物诱导HepG2细胞凋亡并阻止其G2 / M期细胞周期。确定了GA中维持抗肿瘤作用的支架主要部分的确定,并报道了基于笼状药效团的SAR,这将为今后的抗癌药物开发研究提供关键信息。
