Pyrazolopyrimidiner som CRF-receptorantagonister

摘要

This invention concerns compounds of formula (I), including the stereoisomers and the pharmaceutically acceptable acid addition salt forms thereof, wherein R<1> is NR<4>R<5> or OR<5>; R<2> is C1-6alkyl, C1-6alkyloxy or C1-6alkylthio; R<3> is hydrogen, C1-6alkyl, C1-6alkylsulfonyl, C1-6alkylsulfoxy or C1-6alkylthio; R<4> is hydrogen, C1-6alkyl, mono- or di(C3-6cycloalkyl)methyl, C3-6cycloalkyl, C3-6alkenyl, hydroxyC1-6alkyl, C1-6alkylcarbonyloxyC1-6alkyl or C1-6alkyloxyC1-6alkyl; R<5> is C1-8alkyl, mono- or di(C3-6cycloalkyl)methyl, Ar<1>CH2, C1-6alkyloxyC1-6alkyl, hydroxyC1-6alkyl, C3-6alkenyl, thienylmethyl, furanylmethyl, C1-6alkylthioC1-6alkyl, morpholinyl, mono- or di(C1-6alkyl)aminoC1-6alkyl, di(C1-6alkyl)amino, C1-6alkylcarbonylC1-6alkyl, C1-6alkyl substituted with imidazolyl; or a radical of the formula -Alk-O-CO-Ar<1>; or R<4> and R<5> taken together with the nitrogen atom to which they are attached may form an optionally substituted pyrrolidinyl, piperidinyl, homopiperidinyl or morpholinyl group; having CRF receptor antagonistic properties; pharmaceutical compositions containing such compounds as active ingredients; methods of treating disorders related to hypersecretion of CRF such as depression, anxiety, substance abuse, by administering an effective amount of a compound of formula (I).
