4-(1,3-Dimethoxyprop-2-ylamino)-2,7-dimethyl-8-(2,4-dichlorophenyl)pyrazolo[1,5-a]-1,3,5-triazine: A Potent, Orally Bioavailable CRF1 Receptor Antagonist
摘要:
Structure-activity studies; in the pyrazolo[1,5-a]-1,3,5-triazine series led to the discovery that compound 11i (DMP696) is a potent hCRF(1) receptor antagonist (K-i = 1.7 nM vs 7.5 nM for alpha-hel-CRF(9-41), hCRF(1) adenylate cyclase IC50 = 82 nM vs 286 nM for alpha-hel-CRF(9-41)). Compound 11i has excellent oral pharmacokinetic profiles in rats and dogs (37% and 50% oral bioavailabilities, respectively). This compound displays good activity in the rat situational anxiety model (MED = 3 mg/kg (po)), whereas a literature standard 1 (CP154526-1) was inactive (MED > 30 mg/kg (po)). Analogue 11i reduced stereotypical mouth movements in rhesus monkeys by 50% at 21 mg/kg (po) using the human intruder paradigm. Overall, the profile of pyrazolotriazine 11i indicates that hCRF1 receptor antagonists may be anxiolytic agents, which have reduced motor side effect profiles.

New 3‐amino‐ and 5‐aminopyrazoles were synthesised. 3‐Aminopyrazoles exert a strong anticonvulsant effect. 4‐Chlorophenyl‐3‐( morpholin‐4‐yl)‐1H‐pyrazole 2 distinctively blocks sodium channels and is strongly effective in the Maximal Electroshock Seizure (MES) test.
