在过去的二十年里,我们对蛋白质-蛋白质相互作用(PPI)的理解以及如何用小分子疗法靶向它们取得了许多进展。在2004年,我们回顾了一些早期的成功;从那时起,已经开发了针对不同蛋白质复合物的有效抑制剂,并且化合物现在正在针对六个靶点进行临床试验。令人惊讶的是,许多这些PPI临床候选药物具有典型的“铅样”或“药物样”分子的效率指标,并且是口服可用的。成功的发现工作整合了多个学科,并利用了所有基于目标的发现的现代工具-结构,计算,筛选和生物标志物。随着接口变得越来越复杂,PPI变得越来越具有挑战性,即,因为结合表位展示在一级、二级或三级结构上。在这里,我们回顾了过去十年的进展,重点是PPI抑制剂的性能,已推进到临床试验和PPI药物发现的未来前景。
The past twenty years have seen many advances in our understanding of protein-protein interactions (PPI) and how to target them with small-molecule therapeutics. In 2004, we reviewed some early successes; since then, potent inhibitors have been developed for diverse protein complexes, and compounds are now in clinical trials for six targets. Surprisingly, many of these PPI clinical candidates have efficiency metrics typical of ‘lead-like’ or ‘drug-like’ molecules and are orally available. Successful discovery efforts have integrated multiple disciplines and make use of all the modern tools of target-based discovery - structure, computation, screening, and biomarkers. PPI become progressively more challenging as the interfaces become more complex, i.e., as binding epitopes are displayed on primary, secondary, or tertiary structures. Here, we review the last ten years of progress, focusing on the properties of PPI inhibitors that have advanced to clinical trials and prospects for the future of PPI drug discovery.
