靶点识别和作用机制研究在小分子探针和药物发现中具有重要作用。生物和技术的进步导致越来越多地使用基于细胞的测定来发现新的生物活性小分子。这些研究允许在一开始就在更相关的疾病环境中测试小分子作用,但它们需要后续研究来确定负责观察到的表型的精确蛋白质靶标。目标识别可以通过直接的生物化学方法,遗传相互作用或计算推理来实现。然而,在许多情况下,可能需要结合各种方法来充分表征靶向和脱靶效应,并了解小分子作用的机制。
Target-identification and mechanism-of-action studies have important roles in small-molecule probe and drug discovery. Biological and technological advances have resulted in the increasing use of cell-based assays to discover new biologically active small molecules. Such studies allow small-molecule action to be tested in a more disease-relevant setting at the outset, but they require follow-up studies to determine the precise protein target or targets responsible for the observed phenotype. Target identification can be approached by direct biochemical methods, genetic interactions or computational inference. In many cases, however, combinations of approaches may be required to fully characterize on-target and off-target effects and to understand mechanisms of small-molecule action.
