- 8-(4-Methoxyphenyl)pyrazolo[1,5-a]-1,3,5-triazines: Selective and centrally active corticotropin-releasing factor receptor-1 (CRF1) antagonists
-
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 (CRF1) receptor antagonists. CRF1 receptor antagonists may be potential anxiolytic or antidepressant drugs. This research culminated in the discovery of analogue 12-3, which is a potent, selective CRF1 antagonist (hCRF1 IC50 ) 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.
