that the 2-pyridyl isomers acted as dual cardioselective calciumchannel agonists (GPLA)/smooth muscle selective calciumchannelantagonists (GPILSM). In contrast, the 3-pyridyl and 4-pyridyl isomers acted as calciumchannel agonists on both GPLA and GPILSM. In the C-4 2-pyridyl group of compounds, the size of the C-5 alkyl (or cycloalkyl) ester substituent was a determinant of GPILSM antagonist activity

1,4-Dihydropyridines of the formula ##STR1## in which n is 0,1 or 2, and R.sup.1 to R.sup.7 can have a wide variety of meanings, which possess inotropic action, and many of which are new, are useful in increasing the influx of Ca.sup.++ into cells, particularly in combatting coronary and vascular diseases, hypertension swelling in the mucous membranes and diseases involving increased blood sugar or an incorrect salt and fluid balance.
