AbstractÐStructure±affinity relationships (SARs) of non-peptide CRF1 antagonists suggest that such antagonists can be constructed of three units: a hydrophobic unit (Up-Area), a proton accepting unit (Central-Area), and an aromatic unit (Down-Area). Recently, various non-peptide corticotropin-releasing factor1 (CRF1) receptor antagonists obtained by modification of the Central-Area have been reported. In contrast, we modified the Up-Area ...
