Synthesis of new pyrimidine-fused derivatives as potent and selective antidiabetic α-glucosidase inhibitors
摘要:
The synthesis of a set of pyrimidine-fused derivatives (L1-L8), resulting from the incorporation of different fragments on the pyrimidine-fused heterocycle (PFH) of the earlier reported alpha-glucosidase (alpha-Gls) inhibitor (C1-C5), allowed the discovery of new ligands with modest and selective inhibitory activity. The PFH core (substructure 2) was proved to play a significant role in their inhibitory properties. Additionally, the substituent on substructures 1 and 3 of the heterocyclic ring was demonstrated to be important in the enzyme inhibitory action of the pyrimidine-fused derivatives. Moreover, these ligands show selective inhibitory properties for alpha-Gls over porcine pancreatic alpha-amylase (alpha-Amy) which is important in terms of their reduced susceptibility for the possible development of intestinal disturbance side effects. Therefore, low to moderate alpha-Amy inhibition with effective alpha-Gls inhibitory action may offer a better therapeutic strategy. Overall, these compounds can potentially offer a new opportunity to develop novel antidiabetic drugs with selective inhibitory action against alpha-Gls. (C) 2013 Elsevier Ltd. All rights reserved.
