  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 iridium complex Cp*Ir@CTF, which is synthesized by the coordinative immobilization of [Cp*IrCl2]2 on a functionalized covalent triazine framework (CTF), was found to be a general and highly efficient catalyst for the N-methylation of amines with methanol in the presence of carbonate. Under environmentally benign conditions, a variety of desirable products were obtained in high yields with complete

  铱络合物Cp * Ir @ CTF是通过将[Cp * IrCl 2 ] 2配位固定在功能化的共价三嗪骨架（CTF）上合成的，它是一种通用的高效N-甲基化催化剂在碳酸盐的存在下，将胺与甲醇反应。在环境友好的条件下，以高收率获得了各种理想的产品，具有完全的选择性和对官能团的友好性。此外，合成的催化剂可以通过简单的过滤进行再循环，而在第六次循环后没有明显的催化活性损失。值得注意的是，这项研究显示了共价三嗪骨架负载的过渡金属催化剂在氢自动转移过程中的潜力。

  The direct N-monomethylation of aromatic primary amines, including arylamines, arylsulfonamides and amino-azoles, using methanol as a methylating agent has been accomplished in the presence of a [Cp*IrCl2]2/NaOH system. From both synthetic and environmental points of view, the reaction is highly attractive because of low catalyst loading, broad substrate scope and excellent selectivities.

  芳族伯胺的直接N-单甲基化反应，包括芳胺，芳基磺酰胺和氨基唑甲醇在[Cp * IrCl 2 ] 2 / NaOH体系的存在下已经完成了甲基化。从合成和环境的角度来看，由于催化剂用量低，底物范围宽和选择性好，该反应具有很高的吸引力。
