We designed and synthesized a series of 2-Ar-8-methyl-5-alkylaminolquinolines as potent corticotropin-releasing factor 1 (CRF1) receptor antagonists. The structure-activity relationships of substituents at each position (R-3, R-5, R-5', and R-8) was investigated. By derivatization, three compounds (6, 14b, and 14c) were identified as orally active CRF1 receptor antagonists. (C) 2012 Elsevier Ltd. All rights reserved.
Synthesis and structure–activity relationships of 8-substituted-2-aryl-5-alkylaminoquinolines: Potent, orally active corticotropin-releasing factor-1 receptor antagonists
We previously reported a series of 8-methyl-2-aryl-5-alkylaminoquinolines as a novel class of corticotropin-releasing factor-1 (CRF1) receptorantagonists. A critical issue encountered for this series of compounds was low aqueous solubility at physiological pH (pH 7.4). To address this issue, derivatization at key sites (R2, R3, R5, R5′, and R8) was performed and the relationships between structure
A series of 5-alkylaminolquinolines was designed and synthesized as potential novel CRF1 receptor antagonists. The structure-activity relationships (SARs) of the substituents on each position (R-2, R-3, R-5 and R-5') were investigated. (C) 2012 Elsevier Ltd. All rights reserved.
