  摘要：

  We have previously shown that 3-phenylpyrazolo[1,5-a]pyrimidines exemplified by 8 were potent antagonists of the human corticotropin-releasing factor-1 receptor. A series of 3-pyridylpyrazolo[1,5-a]pyrimidines 15, 25-30, 34, and 35 containing a weakly basic pyridine ring at the 3-position of the bicyclic nucleus was designed to reduce lipophilicity from the initial leads such as 7. Here, we showed that these 3-pyridyl compounds exhibited potent antagonists at the human CRF1, receptor. Moreover, the hydrophilic and weakly basic pyridine moiety increased the water solubility of some analogues. Compound 26h exhibited good binding affinity at the human CRF1 receptor with a K-i value of 3.5 nM. As a functional antagonist, it dose-dependently inhibited CRF-stimulated cAMP production in cells expressing the CRF1 receptor [IC50 = 50 nM), and CRF-stimulated ACTH release from cultured rat pituitary cells [IC50 = 20 nM). 26h had a log P value of 4.9 and water solubility of greater than 10 mg/mL. Pharmacokinetic studies in rats showed that 26h was orally bioavailable and able to penetrate into the brain. 26h has been demonstrated in vivo efficacy in animal behavioral models that measure anxiolytic activity. These results suggest that analogues from this series were potent CRF1, receptor antagonists with proper physicochemical properties and good pharmacokinetic profiles. 26h was developed into a clinical compound and exhibited efficacy in patients with major depression.

  An efficient palladium-catalyzed synthesis of 3-arylpyrazolo[1,5-a]pyrimidines has been investigated. The key step in the synthesis is a Suzuki biaryl coupling of 3-bromo-2,5-dimethyl-7-aminopyrazolo[1,5-a]pyrimidines with arylboronic acids to provide 3-arylpyrazolo[1,5-a]pyrimidines in moderate to good yield. The synthetic utility of this methodology has been demonstrated by a concise and convergent
