Quinazolin derivatives as emerging alpha-glucosidase inhibitors

A series of C-7 substituted-2-morpholino-N-(pyridin-2-ylmethyl) quinazolin-4-amine have been synthesized and biochemical assay was examined against α-glucosidase function inhibition activity. A structure activity and structure property relationship study was experimented to surface the new hit compound. This study led to the identification of C7substituted quinazolines with minimum inhibitory concentrations (MICs) in the preffered micromolar range in addition with interesting physicochemical properties. Biological evaluation yielded eight analogs which rose with significant α-glucosidase inhibition potency (IC50 values < 2 μM, where reference compound (Acarbose) potency value is IC50 = 0.586 uM) and could be promising candidates for further lead optimization.
