自 1981 年分离出应激分泌肽以来,人们一直在寻找促肾上腺皮质激素释放因子 (CRF) 受体拮抗剂。尽管有证据表明 CRF1 拮抗剂作为抗抑郁药的功效有限,但 CRF1 拮抗剂可能是治疗焦虑和成瘾的新型药物疗法。在理解 CRF 家族受体配体-受体相互作用的双域模型方面取得的进展可能会产生化学上新颖的 CRF1 受体拮抗剂,包括肽 CRF1 拮抗剂、具有信号转导选择性的拮抗剂和通过细胞外(而不是跨膜)域起作用的非肽 CRF1 拮抗剂。已经鉴定出符合普遍药效团并表现出药物样药代动力学特性的新型配体。 CRF1拮抗剂的治疗效用很快就会变得更加清晰:几种小分子目前正在进行针对抑郁症、焦虑症和肠易激综合征的II/III期临床试验。
Corticotropin-releasing factor (CRF) receptor antagonists have been sought since the stress-secreted peptide was isolated in 1981. Although evidence suggests the limited efficacy of CRF1 antagonists as antidepressants, CRF1 antagonists might be novel pharmacotherapies for anxiety and addiction. Progress in understanding the two-domain model of ligand–receptor interactions for CRF family receptors might yield chemically novel CRF1 receptor antagonists, including peptide CRF1 antagonists, antagonists with signal transduction selectivity and nonpeptide CRF1 antagonists that act via the extracellular (rather than transmembrane) domains. Novel ligands that conform to prevalent pharmacophore and exhibit drug-like pharmacokinetic properties have been identified. The therapeutic utility of CRF1 antagonists should soon be clearer: several small molecules are currently in Phase II/III clinical trials for depression, anxiety and irritable bowel syndrome.
