title: CRHR1 antagonists as novel treatment strategies.
abstract: Research has provided considerable evidence for the hypothesis that corticotropin-releasing hormone (CRH), the key central coordinator of stress-hormone homeostasis, also plays a role in the development and course of depression and anxiety disorders. Studies using animal models of anxiety, as well as mouse mutants, in which the gene coding for the CRH type 1 receptor (CRHR1) was genetically deleted supported the notion that enhanced CRH/CRHR1 signaling underlies depression and anxiety disorders. Therefore, a number of small nonpeptide molecules that antagonize CRHR1 have been developed. In animal models, these molecules had anxiolytic and other stress-alleviating effects. An initial clinical study showed that CRHR1 antagonism has beneficial effects on depression and anxiety symptoms at doses unharmful to neuroendocrine stress responsivity.
