  Novel benzimidazole derivatives as phosphodiesterase 10A (PDE10A) inhibitors with improved metabolic stability

  摘要：

  In this study, we report the identification of potent benzimidazoles as PDE10A inhibitors. We first identified imidazopyridine 1 as a high-throughput screening hit compound from an in-house library. Next, optimization of the imidazopyridine moiety to improve inhibitory activity gave imidazopyridinone 10b. Following further structure-activity relationship development by reducing lipophilicity and introducing substituents, we acquired 35, which exhibited both improved metabolic stability and reduced CYP3A4 time-dependent inhibition.

  Preparations of 2-hydroxy- and 2-mercapto-1H-imidazo[4,5-blpyrazines from pyrazine-2,3-diamines are described. Methylation of 1H-imidazo[4,5-b]pyrazine-2(3H)-thione with methyl iodide and diazomethane gave some S, N1, N3 and N4 methyl derivatives; and 1H-imidazo[4,5-b]pyrazin- 2(3H)-one with diazomethane gave products which involved O, N1, N3 and N4 methylation. These products showed slight activity as amplifiers of phleomycin but the benzothiazoles (10b) and (10c) (as hydrobromides) showed three and four star activity respectively.
