Genome-wide-association studies in chronic low back pain patients identified sepiapterin reductase as a high interest target for developing new analgesics. Here we used 19F NMR fragment screening for the discovery of novel, ligand-efficient SPR

A promising lead compound 1 of a benzimidazole series has been identified as a corticotropin-releasing factor 1 (CRF1) receptor antagonist. In this study, we focused on replacement of a 7-alkylamino group of 1, predicted to occupy a large lipophilic pocket of a CRF1receptor, with an aryl group. During the course of this examination, we established new synthetic approaches to 2,7-diarylaminobenzimidazoles. The novel synthesis of 7-arylaminobenzimidazoles culminated in the identification of compounds exhibiting inhibitory activities comparable to the alkyl analog 1. A representative compound, p-methoxyanilino analog 16g, showed potent CRF binding inhibitory activity against a human CRF1receptor and human CRF1receptor antagonistic activity (IC50?=?27?nM, 56?nM, respectively). This compound exhibited ex vivo125I-Tyr0(125I-CRF) binding inhibitory activity in mouse frontal cortex, olfactory bulb, and pituitary gland at 20?mg/kg after oral administration. In this report, we discuss the structure–activity-relationship of these 7-arylamino-1H-benzimidazoles and their synthetic method.
