The invention provides compounds of the formula (I):
and salts thereof; wherein
A is a group NR3S02 or S02NR3;
B is an acyclic hydrocarbon group having from one to six linear carbon atoms, provided that the carbon atom attached to the nitrogen atom is saturated;
Y is C02H or a group hydrolysable to C02H;
R' is phenyl optionally substituted by one or more substituents chosen from the group comprising halogen, C1-4alkyl, C1-6acyl, C1-4alkoxy, nitro and trifluoromethyl;
R2 is hydrogen or one or more C 1-4alkyl substituents located at the 1, 3 and 4 positions of the isoquinoline ring; and
R3 is hydrogen or C1-6alkyl.
Also disclosed are pharmaceutical compositions containing the compounds, methods for making them and the use of the compounds as thromboxane A2 antagonists.
