Abstract: A compound of the formula (1) or a pharmaceutically-acceptable salt, or pro-drug thereof; (1) wherein, for example, R4 is halo or (1-4C)alkyl; A is phenylene or heteroarylene; n is 0, 1 or 2; m is 0, 1 or 2; R1 is halo, cyano or carboxy; R2 is for example methyl; R3 is for example selected from halo(1-4C)alkyl, dihalo(1-4C)alkyl, trifluoromethyl, hydroxy(1-4C)alkyl, dihydroxy(2-4C)alkyl, trihydroxy(3-4C)alkyl, cyano(1-4C)alkyl (optionally substituted on alkyl with hydroxy), (1-4C)alkoxy(1-4C)alkyl, (1-4C)alkoxy(1-4C)alkoxy(1-4C)alkyl, di[(1-4C)alkoxy](1-4C)alkyl, (hydroxy)[(1-4C)alkoxy](1-4C)alkyl; possess glycogen phosphorylase inhibitory activity and accordingly have value in the treatment of disease states associated with increased glycogen phosphorylase activity. Processes for the manufacture of compounds and pharmaceutical compositions containing them are described.

Abstract: Heterocyclic amides of formula (1) wherein: is a single or double bond; A is phenylene or heteroarylene; m is 0, 1 or 2; n is 0, 1 or 2; R1 is selected from for example halo, nitro, cyano, hydroxy, carboxy; r is 1 or 2; Y is —NR2R3 or —OR3; R2 and R3 are selected from for example hydrogen, hydroxy, aryl, heterocyclyl and C1-4alkyl(optionally substituted by 1 or 2 R8 groups); R4 is selected from for example hydrogen, halo, nitro, cyano, hydroxy, C1-4alkyl, and C1-4alkanoyl; R8 is selected from for example hydroxy, —COCOOR9, —C(O)N(R9)(R9), —NHC(O)R9, (R9)(R10)N— and —COOR9; R9 and R10 are selected from for example hydrogen, hydroxy, C1-4alkyl (optionally substituted by 1 or 2 R13); R13 is selected from hydroxy, halo, trihalomethyl and C1-4alkoxy; or a pharmaceutically acceptable salt or pro-drug thereof; possess glycogen phosphorylase inhibitory activity and accordingly have value in the treatment of disease states associated with increased glycogen phosphorylase activity.
