    具有葫芦素样功能作为B-Raf抑制剂的类固醇骨架的结构优化和生物学筛选。
    摘要:
    通过靶向黑色素瘤中常见的突变B-Raf来抑制有丝分裂原激活的蛋白激酶(MAPK)途径已成为开发药物和候选药物的实用方法。为了扩展当前报道的用于靶向MAPK途径的结构支架,分子对接研究导致将与葫芦素类天然产物相关的α,β-不饱和酮侧链安装在雌激素核心上。醛醇缩合反应,以及安装Δ9,11烯烃以组装拟顺式B / C环连接处的配置。这些葫芦素样特征的组合产生了一种针对A-375突变B-Raf细胞系具有增强的生物学特性的化合物,因为它们具有细胞毒性和对磷酸化的细胞外信号调节激酶(ERK)的抑制活性。

    pathway by targeting the commonly occurring mutated B‐Raf in melanoma has become a practical method for the development of drugs and drug candidates. In order to expand upon the currently reported structural scaffolds used to target the MAPK pathway, molecular docking studies led to the installation an α,β‐unsaturated ketone side chain, related to the cucurbitacin class of natural products, on to an estrone
