  SAR analysis of novel non-peptidic NPBWR1 (GPR7) antagonists

  摘要：

  In this Letter we report on the advances in our NPBWR1 antagonist program aimed at optimizing the 5-chloro-2-(3,5-dimethylphenyl)-4-(4-methoxyphenoxy)pyridazin-3(2H)-one lead molecule previously obtained from a high-throughput screening (HTS)-derived hit. Synthesis and structure-activity relationships (SAR) studies around the 3,5-dimethylphenyl and 4-methoxyphenyl regions resulted in the identification of a novel series of non-peptidic submicromolar NPBWR1 antagonists based on a 5-chloro-4-(4-alkoxyphenoxy)-2-(benzyl)pyridazin-3(2H)-one chemotype. Amongst them, 5-chloro-2-(9H-fluoren-9-yl)-4-(4-methoxyphenoxy)pyridazin-3(2H)-one 9h (CYM50769) inhibited NPW activation of NPBWR1 with a submicromolar IC50, and displayed high selectivity against a broad array of off-targets with pharmaceutical relevance. Our medicinal chemistry study provides innovative non-peptidic selective NPBWR1 antagonists that may enable to clarify the biological role and therapeutic utility of the target receptor in the regulation of feeding behavior, pain, stress, and neuroendocrine function.
