Novel thienopyridones with antihypertensive activity have the formula 1,
wherein the ring A represents an optionally substituted thiophene ring; m is 0 or 1; n is 0,1 or 2; R is lower alkyl and R1 is lower alkyl.
The fused thieno-ring may carry one or two substituents.
Formula I encompasses thieno [3,2-b]pyridones. thieno[3,4-b]pyridones and thieno [2.3-b]pyridones.
Processes for preparing the novel thienopyridones and pharmaceutical compositions containing them are described. Pharmaceutically acceptable acid addition salts of the compounds of formula I are also described.
The thienopyridones of formula I are antihypertensive agents and are also indicated for use in treating heart failure and ischaemic heart disease.
