Different resistance mechanisms, especially, T790M secondary acquired point mutation and in some cases amplification of cMET, have been a major setback for the lung cancer therapies.
The current in silico study explored the small molecules which can act as putative EGFR (T790M)-cMET dual inhibitors. Databases were first filtered and subsequently cross filtered, initially by thoroughly validated pharmacophore models for both targets. As per score and interactions obtained in docking, the molecules were subjected to molecular dynamics simulations, to study the stability and binding orientations of their complexes with target proteins.
Molecular dynamics simulations predicted three hits to possess good binding affinities and stability for EGFR (T790M) and cMET, which can be claimed to be potential dual inhibitors.
不同的耐药机制,尤其是T790M二次获得性点突变以及在某些情况下cMET的扩增,一直是肺癌治疗的主要障碍。
当前的计算机模拟研究探索了可作为假定的表皮生长因子受体(T790M)-cMET双重抑制剂的小分子。首先对数据库进行筛选,随后进行交叉筛选,最初是通过针对两个靶点经过充分验证的药效团模型。根据对接中获得的评分和相互作用,对这些分子进行分子动力学模拟,以研究它们与靶蛋白复合物的稳定性和结合方向。
分子动力学模拟预测有三个命中物对表皮生长因子受体(T790M)和cMET具有良好的结合亲和力和稳定性,可称其为潜在的双重抑制剂。
