A novel class of dialkyl 1,4‐dihydro‐2,6‐dimethyl‐4‐[4‐(1‐methoxycarbonyl‐ 1,4‐dihydropyridyl)]‐3,5‐pyridinedicarboxylates (8—14) were synthesized and evaluated as calciumchannelantagonists. The differences in activity among members of this new class of compounds was less than one log unit (IC50 range of 1.12 × 10‐6 to 8.57 × 10‐6 M), relative to the reference drug nifedipine (IC50 = 1.43 × 10‐8
