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

Formula (I) ((Ia) and (Ib)) compounds wherein (i) X1 is N and X2 is S, (ii) X1 is CR7 and X2 is S, (iii) X1 is N and X2 is NR2, or (iv) X1 is CR7 and X2 is O, including stereoisomers, tautomers, metabolites and pharmaceutically acceptable salts thereof, are useful for inhibiting the delta isoform of PI3K, and for treating disorders mediated by lipid kinases such as inflammation, immunological, and cancer. Methods of using compounds of Formula (I) for in vitro, in situ, and in vivo diagnosis, prevention or treatment of such disorders in mammalian cells, or associated pathological conditions, are disclosed.
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.
