1,4-dihydropyridine derivatives of the formula (I):
(I) and pharmaceutically acceptable salts;
wherein
R is aryl or heteroaryl;
R1 and R2 are each independently C1-C4 alkyl or 2-methoxyethyl; Y is -(CH2)n-, -CH2CH(CH3)- or -CH2C(CH3)2-; X is a group of the formula:
wherein
R3 is H, het, -(CH2)n-het, -NH-het, -NH-(CH2)n-het, -O-het, -O-(CH2)n-het, -(CH2)n-OH, -NR6R7, -(CH2)nNR6R7 or -NH--(CH2)pNR6R7;
R4 is H, C1-C4 alkyl, -(CH2)pNR6R7, -(CH2)p-OH or -(CH2)n-het; and
R5 is H, C1-C4 alkyl or phenyl; wherein
R6 and R7 are each independently H or C1-C4 alkyl or the two groups R6 and R7 are taken together with the nitrogen atom to which they are attached to form a pyrrolidinyl, piperidino, morpholino, piperazinyl or N-(C1-C4 alkyl)piperazinyl group;
n is 1-4 and p is 2-4;
with the proviso that when R4 is H or C1-C4 alkyl, R3 is not H or -NR6R7.
These compounds are useful as anti-ischaemic and antihypertensive agents.
