Abstract: This report describes the syntheses and structure-activity relationships of 8-(4-methoxyphenyl)pyrazolo[1,5-a]-1,3,5-triazine corticotropin releasing factor receptor-1 (CRF(1)) receptor antagonists. CRF(1) receptor antagonists may be potential anxiolytic or antidepressant drugs. This research culminated in the discovery of analogue 12-3, which is a potent, selective CRF(1) antagonist (hCRF(1) IC(50) = 4.7 +/- 2.0 nM) with weak affinity for the CRF-binding protein and biogenic amine receptors. This compound also has a good pharmacokinetic profile in dogs. Analogue 12-3 is orally effective in two rat models of anxiety: the defensive withdrawal (situational anxiety) model and the elevated plus maze test. Analogue 12-3 has been advanced to clinical trials.
