The enantiomers of the 1,4-dihydropyridine (DHP) niguldipine (3-methyl-5-[3-(4,4-diphenyl-1-piperidinyl)-propyl]- 1,4-dihydro-2,6-dimethyl-4-(3-nitrophenyl)-pyridine-3,5-dicarboxylate- hydrochloride) were investigated with respect to their interaction with 1,4-DHP receptors on L-type Ca2+ channels and alpha-adrenoceptors. The Ki values for niguldipine were dependent on the membrane protein concentrations in the
