EP1224195B1 — C-aryl glucoside sglt2 inhibitors

USPTO Abstract

SGLT2 inhibiting compounds are provided having formula (I) where R?1, R2, and R2a¿ are independently hydrogen, OH, OR5, lower alkyl, CF¿3?, OCHF2, OCF3, SR?5i¿ or halogen, or two of R?1, R2 and R2a¿ together with the carbons to which they are attached can form an annelated five, six or seven membered carbocycle or heterocycle; R?3 and R4¿ are independently hydrogen, OH, OR5a, OAryl, OCH¿2?Aryl, lower alkyl, cycloalkyl, CF3, -OCHF2, -OCF3, halogen, -CN, -CO2R?5b, -CO¿2H, -COR6b, -CH(OH)R6c, -CH(OR?5h)R6d, -CONR6R6a¿, -NHCOR5c, -NHSO¿2R?5d, -NHSO¿2?Aryl, Aryl, -SR?5e, -SOR5f, SO¿2R5g, SO2Aryl, or a five, six or seven membered heterocycle, or R?3 and R4¿ together with the carbons to which they are attached form an annelated five, six or seven membered carbocycle or heterocycle; R?5, R5a, R5b, R5c, R5d, R5e, R5f, R5g, R5h, and R5I¿ are independently lower alkyl; R?6, R6a, R6b, R6c and R6d¿ are independently hydrogen, alkyl, aryl, alkylaryl or cycloalkyl, or R?6 and R6a¿ together with the nitrogen to which they are attached form an annelated five, six or seven membered heterocycle; A is O, S, NH, or (CH¿2?)n where n is 0 - 3. A method is also provided for treating diabetes and related diseases employing an SGLT2 inhibiting amount of the above compound alone or in combination with another antidiabetic agent or other therapeutic agent.
