Sodium-glucose cotransporter 2 (SGLT2) inhibitors belong to a novel class of oral anti-hyperglycemic agents that reduce plasma glucose concentrations by the inhibition of glucose reabsorption in the kidney thereby inducing glucosuria.[1,2]

Marketed SGLT2 inhibitors [1] also called gliflozins are C-glycosyl derivatives having diaryl methane type aglycone (1), in which the second aryl moiety can be a heteroaromatic ring (thiophene or benzothiophene), as well. Several promising inhibitors were found among glucose derivatives wherein the first aryl unit was replaced by a hetrarene ring such as thiophene, pyrrole, thiazole, pyridine, pyrazine and pyridazine.[2] In connection with this, synthesis of similar arylmethyl substituted C-β-D-glucopyranosyl heterocycles (i.e. pyrimidines (2a) and oxadiazoles (2b,c)) was envisaged in order to broaden the structure-activity relationship studies of such type of SGLT2 inhibitors. 

In the presentation the syntheses of 2a-c and preliminary results of SGLT2 inhibition will be reported.
