  Discovery of N-(1-Ethylpropyl)-[3-methoxy-5-(2-methoxy-4-trifluoromethoxyphenyl)-6-methyl-pyrazin-2-yl]amine 59 (NGD 98−2): An Orally Active Corticotropin Releasing Factor-1 (CRF-1) Receptor Antagonist

  摘要：

  The design, synthesis, and structure-activity relationships of a novel series of pyrazines, acting as corticotropin releasing factor-1 (CRF-1) receptor antagonists, are described. Synthetic methodologies were developed to prepare a number of substituted pyrazine cores utilizing regioselective halogenation and chemoselective derivatization. Noteworthy, an efficient 5-step synthesis was developed for the lead compound 59 (NGD 98-2), which required no chromatography. Compound 59 was characterized as an orally bioavailable, brain penetrant, and highly selective CRF-1 receptor antagonist. Occupancy of rat brain CRF-1 receptors was quantified using ex vivo receptor occupancy assays, using both brain tissue homogenates as well as brain slices receptor autoradiography. Behaviorally, oral administration of 59 significantly antagonized CRF-induced locomotor activity at doses as low as 10 mg/kg and dose-dependently reduced the restraint stress-induced ACTH increases.

• Heteroatom-linked indanylpyrazines are corticotropin releasing factor type-1 receptor antagonists

  日期：2007.11

  Low nanomolar corticotropin releasing factor type-1 (CRF1) receptor antagonists containing unique indanylamines were identified from the heteroatom-linked pyrazine chemotype. The most potent indanylpyrazine had a K-i = 11 +/- 1 nM. The oxygen-linked pyrazinyl derivatives were prepared through a copper-catalyzed coupling of a pyridinone to a bromo- or iodopyrazine.
