Synthesis, biological evaluation and molecular modeling of substituted 2-aminobenzimidazoles as novel inhibitors of acetylcholinesterase and butyrylcholinesterase
A series of novel 2-aminobenzimidazolederivatives were synthesized under microwave irradiation. Their biological activities were evaluated on acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE). A number of the 2-aminobenzimidazolederivatives showed good inhibitory activities to AChE and BuChE. Among them, compounds 9, 12 and 13 were found to be >25-fold more selective for BuChE than AChE

high-throughput screening. KEY RESULTS The original compound, M084, was a potent inhibitor of both TRPC4 and TRPC5, but was also a weak inhibitor of TRPC3. Structural modifications of the lead compound resulted in the identification of analogues with improved potency and selectivity for TRPC4 and TRPC5 channels. The aminobenzimidazole derivatives rapidly inhibited the TRPC4- and TRPC5-mediated currents when applied
The direct N-alkylation of 2-aminoimidazoles to give the corresponding 2-(N-alkylamino)imidazoles was accomplished using alcohols as alkylating agents in the presence of a [Cp*IrCl2]2/K2CO3system. The iridium-catalyzed regioselective reaction is simple, efficient, general, and environmentally benign.
