This invited Team Profile was created by the Tiwary group, University of Maryland, College Park (USA) and the Seeliger group, Stony Brook University, New York (USA). They recently published an article on the previously made observation through in-cell screening that the blockbuster cancer drug Gleevec has the same binding affinity, yet different dissociation kinetics against wild-type and N368S-mutated Abl kinase. Through all-atom enhanced molecular dynamics simulations guided by statistical mechanics and information theory, they were able to explain the mechanistic basis of this perplexing observation. Their work has ramifications for how pharmaceutical drugs might experience kinetic resistance due to mutations.

这份特邀团队简介由马里兰大学帕克分校的 Tiwary 团队和纽约州立大学石溪分校的 Seeliger 团队共同撰写。他们最近发表了一篇文章,通过细胞内筛选观察到重磅抗癌药物格列卫对野生型和 N368S 突变型 Abl 激酶具有相同的结合亲和力,但解离动力学却不同。通过基于统计力学和信息论的全原子增强分子动力学模拟,他们能够解释这一令人费解的观察结果的机制基础。他们的工作对于解释由于突变导致药物如何产生动力学耐药性具有重要意义。“蛋白柔性和解离途径的差异化可解释激酶中耐药突变的发生”,M.
