Compositions containing dihydropyridine derivatives which are useful for treating congestive heart failure, hypertension, or angina have the formula: ##STR1## or a pharmaceutically acceptable acid addition salt thereof, wherein n is an integer from 0 to 8; Y is --O--, --NH--, --NR.sub.2 --, --S--, --S(O)--, --S(O).sub.2 --, or a bond; R.sub.1 and R.sub.2 are each independently A.sub.1, A.sub.2, A.sub.3 or A.sub.4 where A.sub.1 is --(CH.sub.2).sub.m (CHOH).sub.p CH.sub.2 OH; A.sub.2 is --(CH.sub.2).sub.q CH.sub.(3-r) [(CH.sub.2).sub.s OH].sub.r ; A.sub.3 is --(CH.sub.2).sub.q CH.sub.(3-r) [(CH.sub.2).sub.p COOR.sub.3 ].sub.r ; and A.sub.4 is --(CH.sub.2).sub.m COOR.sub.3 ; where m is an integer from 1 to 8; p is an integer from 0 to 4; q is an integer from 0 to 8; r is 2 or 3; s is an integer from 1 to 4; and R.sub.3 is H or alkyl of 1 to 18 carbon atoms; R.sub.4 is --NO.sub.2, --CF.sub.3, or halo; and R.sub.5 is lower alkyl or --CH.sub.2 CH.sub.2 OCH.sub.3. Also disclosed are optical isomers of the above compounds, as well as intermediates in the preparation of these final products.
Novel dihydropyridine derivatives which are useful for treating congestive heart failure, hypertension, and angina have the formula 1: ##STR1## or a pharmaceutically acceptable acid addition salt thereof, wherein: n is an integer from 0 to 8; Y is --O, --NH, --NR.sub.2, --S, --S(O), --S(O).sub.2, or a bond; R.sub.1 and R.sub.2 are each independently A.sub.1, A.sub.2, A.sub.3 or A.sub.4 where: A.sub.1 is --(CH.sub.2).sub.m (CHOH).sub.p CH.sub.2 OH; A.sub.2 is --(CH.sub.2).sub.q CH.sub.(3-r) [(CH.sub.2).sub.s OH].sub.r ; A.sub.3 is --(CH.sub.2).sub.q CH.sub.(3-r) [(CH.sub.2).sub.p COOR.sub.3 ].sub.r ; and A.sub.4 is --(CH.sub.2).sub.m COOR.sub.3 ; where: m is an integer from 1 to 8; p is an integer from 0 to 4; q is an integer from 0 to 8; r is 2 or 3; s is an integer from 1 to 4; and R.sub.3 is H or alkyl of 1 to 18 carbon atoms; R.sub.4 is --NO.sub.2, --CF.sub.3, or halo; and R.sub.5 is lower alkyl or --CH.sub.2 CH.sub.2 OCH.sub.3.
