A 5-isoquinolinesulfonyl derivative of Formula (I):
wherein
f is zero or one;
m and n each is an integer of one to nine;
m+n is an integer of at least one;
R1 is a hydrogen atom, a C1-10 alkyl group, a C5-6cycloalkyl group or an aryl group; or
R2 and R3 each is a hydrogen atom, a C1-10 alkyl group, a C5-6 cycloalkyl group, an aryl group or an aralkyl group;
R2 and R3 are C1-6 alkylene groups and linked directly or through an oxygen atom to form a 5- to 7-membered heterocyclic ring with the adjacent nitrogen atom; or the
group is a
group wherein R4 and Rs each is a hydrogen atom, a C1-10 alkyl group, an aryl group or an aralkyl group and R6 is a hydrogen atom, a C1-10 alkyl group, an aryl group, an aralkyl group, a benzoyl group, a cinnamyl group, a cinnamoyl group, a furoyl group or a
group wherein R, is a C1-8 alkyl group, and the pharmaceutically acceptable salt thereof; and a process for the preparation thereof. The compounds of this invention have a relaxatory action for vascular smooth muscle and are useful as a vasodilator and a hypotensor.
