New di:hydro-pyridine cpds. blocking calcium entry into tissue - are 3,5-di:(cyclo)alkyl 1-alkyl-2-haloalkyl 4-phenyl-6-methyl-1,4-di:hydro-3,5-pyridine 3,5-di:carboxylate(s)

摘要

Dihydropyridine derivs. of formula (I) are new where R1 = phenyl opt. substd. by 1 or more of halo, NO2, CN and 1-6C alkyl (opt. substd. by halo); R2 and R3 = 1-6C alkyl or 3-8C cycloalkyl; R4 = 1-6C haloalkyl; R5 0 1-6C alkyl.
