Syntheses and calcium channel antagonist activity of nifedipine analogues with methylsulfonylimidazolyl substituent.
Various diester analogues of nifedipine in which the ortho nitrophenyl group at position 4 is replaced by 1-methyl-2-methylsulfonyl-5-imidazolyl substituent, were synthesized and evaluated as calcium channel antagonists on guinea-pig ileal smooth muscle. Nifedipine was used as a standard. Compound 6n was found to be the most active.
