Design, synthesis and characterization of novel N-heterocyclic-1-benzyl-1H-benzo[d]imidazole-2-amines as selective TRPC5 inhibitors leading to the identification of the selective compound, AC1903
摘要:
The transient receptor potential cation channel 5 (TRPC5) has been previously shown to affect podocyte survival in the kidney. As such, inhibitors of TRPC5 are interesting candidates for the treatment of chronic kidney disease (CKD). Herein, we report the synthesis and biological characterization of a series of N-heterocyclic-1-benzyl-1H-benzo[d]imidazole-2-amines as selective TRPC5 inhibitors. Work reported here evaluates the benzimidazole scaffold and substituents resulting in the discovery of AC1903, a TRPC5 inhibitor that is active in multiple animal models of CKD.
An electrochemical method for the synthesis of N-substituted 2-aminobenzimidazoles through a NaI-mediated desulfurization–cyclization process is reported. This electrosynthesis method utilizes cost-effective NaI as both a mediator and an electrolyte in a catalytic amount (0.2 equiv), replacing traditional oxidizing reagents. N-Substituted o-phenylenediamines and isothiocyanates undergo a thiourea
报道了一种通过 NaI 介导的脱硫环化过程合成N-取代 2-氨基苯并咪唑的电化学方法。这种电合成方法利用经济高效的 NaI 作为介体和催化量(0.2 当量)的电解质,取代了传统的氧化剂。 N-取代的邻苯二胺和异硫氰酸酯经过硫脲形成/环化/脱硫过程,在单个反应容器中提供N-取代的2-氨基苯并咪唑(55个实例,产率高达98%)。重要的是,这种电化学方法适用于克级合成,保持反应效率。
