基于分子对接虚拟筛选MEK1中药抑制活性成分(1)
[摘要] 有丝分裂原活化蛋白激酶激酶1(mitogen-activated protein kinase kinase,MEK1)的过度磷酸化是黑色素瘤成因之一,基于该靶点的中药成分虚拟筛选有望发现中药在治疗黑色素瘤潜在应用价值。采用MEK1晶体构象构建口袋模型和Flex Search模型,模型可很好重现晶体结构,对接配体构象与晶体结构中原配体构象similarity评分为0.784;对接评分与已有MEK1抑制剂活性数据pIC50呈线性关系,R2=0.937,进一步表明虚拟筛选模型可靠。以口袋模型对Lipinski五规则初筛的中药成分库进行分子对接,根据Flex Search模型精筛,最终得到50个总分高于7.0的化合物,该研究给出总分高于阳性对照的前10个中药成分,有望进一步用于MEK1和黑色素瘤抑制的研究。
