受体、酶和离子通道是治疗开发的传统靶点。一种常见的策略是以这些蛋白质为靶点,通过占据正构位置或具有变构相互作用的配体或底物来激活或抑制它们的活性。另一种方法涉及对蛋白质贩运的监管。原则上,这种方法能够使错误折叠和错误发送的突变蛋白恢复功能,通过靶向破坏不需要的蛋白而使其失事,并调节部分表达的野生型(WT)蛋白在其功能作用部位的水平。在这里,我们提出了识别“药物操纵素”的药物发现策略,这是一种小分子,充当分子模板,使原本错误折叠的突变蛋白质正确折叠和路线。
Receptors, enzymes, and ion channels are traditional targets of therapeutic development. A common strategy is to target these proteins with agents that either activate or suppress their activity with ligands or substrates that occupy orthosteric sites or have allosteric interactions. An alternative approach involves regulation of protein trafficking. In principle, this approach enables ‘rescue' of misfolded and misrouted mutant proteins to restore function, ‘shipwrecking' of undesirable proteins by targeting them for destruction, and regulation of levels of partially expressed wild type (WT) proteins at their functional sites of action. Here, we present drug discovery strategies that identify ‘pharmacoperones', which are small molecules that serve as molecular templates and cause otherwise misfolded mutant proteins to fold and route correctly.
