具有生物活性的小分子在细胞生物学的探索中早已被证明是有用的。虽然许多早期的化合物是药物开发工作的副产品,但最近学术界增加的小分子筛选工作已经扩大了所研究的生物过程的全部内容,以包括不具有直接药物利益的生物学领域。许多这些新的生物测定评分小分子诱导的表型变化在细胞甚至有机体水平,因此已被描述为“化学遗传”的屏幕。然而,这种与传统遗传筛选的类比是误导性的;虽然每个基因在传统遗传筛选中突变的机会大致相等,但使用当前小分子文库的化学遗传学方法可以达到的“蛋白质组空间”的量要小得多。因此,需要新的化学生物学方法来用小的药物样分子靶向剩余的“不可药物化的蛋白质组”。
Biologically active small molecules have long proven useful in the exploration of cell biology. While many early compounds were byproducts of drug development efforts, recent increased small molecule screening efforts in academia have expanded the repertoire of biological processes investigated to include areas of biology that are not of immediate pharmaceutical interest. Many of these new bioassays score for small molecule-induced phenotypic changes at the cellular or even organismal level and thus have been described as ‘chemical genetic’ screens. However, this analogy with traditional genetic screens is misleading; whereas each gene has roughly an equivalent chance of being mutated in a traditional genetic screen, the amount of ‘proteomic space’ that a chemical genetics approach can reach using current small molecule libraries is considerably smaller. Thus, new chemical biology methodologies are needed to target the remaining ‘undruggable proteome’ with small drug-like molecules.
