PubChem is a public repository of small molecules and their biological properties. Currently, it contains more than 25 million unique chemical structures and 90 million bioactivity outcomes associated with several thousand macromolecular targets. To address the potential utility of this public resource for drug discovery, we systematically summarized the protein targets in PubChem by function, 3D structure and biological pathway. Moreover, we analyzed the potency, selectivity and promiscuity of the bioactive compounds identified for these biological targets, including the chemical probes generated by the NIH Molecular Libraries Program. As a public resource, PubChem lowers the barrier for researchers to advance the development of chemical tools for modulating biological processes and drug candidates for disease treatments.
PubChem 是一个小分子及其生物特性的公共数据库。目前,它包含超过 2500 万个独特的化学结构和 9000 万个与数千个大分子靶标相关的生物活性结果。为了探索这个公共资源在药物发现方面的潜在应用,我们系统地按照功能、3D 结构和生物途径对 PubChem 中的蛋白质靶标进行了总结。此外,我们还分析了针对这些生物靶标鉴定的生物活性化合物的效力、选择性和广谱性,包括 NIH 分子文库计划生成的化学探针。作为一个公共资源,PubChem 降低了研究人员开发用于调节生物过程的化学工具和用于治疗疾病的候选药物的门槛。
