Nuclear receptors (NRs) regulate transcription in response to ligand binding and NR modulation allows pharmacological control of gene expression. Although some NRs are relevant as drug targets, the NR1 family, which comprises 19 NRs binding to hormones, vitamins, and lipid metabolites, has only been partially explored from a translational perspective. To enable systematic target identification and validation for this protein family in phenotypic settings, we present an NR1 chemogenomic (CG) compound set optimized for complementary activity/selectivity profiles and chemical diversity. Based on broad profiling of candidates for specificity, toxicity, and off-target liabilities, sixty-nine comprehensively annotated NR1 agonists, antagonists and inverse agonists covering all members of the NR1 family and meeting potency and selectivity standards are included in the final NR1 CG set. Proof-of-concept application of this set reveals effects of NR1 members in autophagy, neuroinflammation and cancer cell death, and confirms the suitability of the set for target identification and validation.
核受体 (NRs) 通过配体结合调节转录,NR 的调节允许对基因表达进行药理学控制。虽然一些 NR 作为药物靶点具有相关性,但从转化的角度来看,仅对 NR1 家族(包含 19 种与激素、维生素和脂质代谢物结合的 NR)进行了部分探索。为了在表型环境中对该蛋白家族进行系统的靶标鉴定和验证,我们提出了一种 NR1 化学生物组学 (CG) 化合物集,该化合物集优化了互补活性/选择性谱和化学多样性。基于对特异性、毒性和非靶标副作用的候选物进行广泛的分析,最终的 NR1 CG 集中包含了 69 种经过全面注释的 NR1 激动剂、拮抗剂和反向激动剂,涵盖了 NR1 家族的所有成员,符合效力和选择性标准。该化合物集的概念验证应用揭示了 NR1 成员在自噬、神经炎症和癌细胞死亡中的作用,并证实了该化合物集适用于靶标鉴定和验证。
