The synthesis and biological evaluation of novel pyrazole based heterocycles attached to sugar moiety lead to creating a new molecular frame work. Nine new compounds were synthesized by reacting ethyl 2-((2-(4-methoxyphenyl)-5-methyloxazol-4-yl) methyl)-3-oxobutanoate derivatives (9a-9c) with different alkyl hydrazines to give various substituted 4-((2-(4-methoxyphenyl)-5-methyloxazol-4-yl) methyl)-5-methyl-1H-pyrazol-3-ol derivatives (10 a-10i) which in turn were reacted with bromoglucose (3)to yield R1, R2 substituted 2-(4-((2-(4-alkoxyphenyl)-5-methyloxazol-4-yl)methyl)-1-alkyl-5-methyl-1H-pyrazol-3-yloxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol (12a-12i). The chemical structures of the synthesized compounds were characterized by means of IR, Mass and NMR spectroscopy. The compounds were screened for anti-diabetic activity by urinary glucose excretion method (UGE). Among the compounds tested, 12f, 12h and12i have exhibited moderate anti-diabetic activity as that of standard drug, remogliflozin. These compounds can be further exploited to get the potent lead compound.
