A small chemical library of 2-aminoimidazole derivatives as BACE-1 inhibitors: Structure-based design, synthesis, and biological evaluation
摘要:
In this work, we report a rational structure-based approach aimed at the discovery of new 2-aminoimidazoles as beta-secretase inhibitors. Taking advantage of a microwave-assisted synthetic protocol, a small library of derivatives was obtained and biologically evaluated. Two compounds showed promising activities in both enzymatic and cellular assays. Moreover, one of them exhibited the capability to cross the blood brain barrier as assessed by the parallel artificial membrane permeability assay. (C) 2011 Elsevier Masson SAS. All rights reserved.

It was accepted ligands played key role for selectivesynthesis and catalysis. A novel pyridinyltriazine skeleton ligand, the corresponding catalysts SBA-15@TZP-Ir and SBA-15@TZP-Ru were synthesized and fully characterized by modern methods. The resulting catalysts showed high catalytic activity in selectivesynthesis of useful substituted perimidines and aminopyrimidines in high yields. Additionally
