    摘要: Imidazolyl and pyridyl derivatives of phenyl substituted 1,4-dihydropyridines of formula (I) ##STR1## wherein Het is ##STR2## A represents a direct linkage, --CH.sub.2 --, CH.sub.2 --CH.sub.2 -- or, when Het is ##STR3## A may also represent --CH.dbd.CH--; R is hydrogen, halogen, C.sub.1 -C.sub.3 alkyl or C.sub.1 -C.sub.3 alkoxy; each of R.sub.3 and R.sub.4 is a C.sub.1 -C.sub.3 alkyl group; one of R.sub.1 and R.sub.2 is a group --OR' wherein R' is a C.sub.1 -C.sub.6 alkyl either unsubstituted or omega substituted by C.sub.1 -C.sub.3 alkoxy or cyano, and the other is, independently,a) a group --OR";b) a group ##STR4## or c) a group --OR.sup.IV wherein R.sup.IV is hydrogen or a substituent selected from:(i) --(CH.sub.2).sub.m --CH.dbd.CH--Ph, ##STR5## are useful as Thromboxane A.sub.2 (TxA.sub.2) Synthase inhibitors and as calcium antagonists.
