摘要:
A 1,4-dihydropyridine derivative having hypotensive activity is represented by the formula (I): in which one of R, and R 2 represents an alkyl group or a group of the formula (II): in which R 5 represents an alkoxy group or a substituted or unsubstituted heterocyclic group and n represents 0 or an integer of 1 - 3, and the other of R, and R 2 represents a group of the formula (III): in which R 6 represents a substituted or unsubstituted aralkyl group and R 7 , R 8 , R 9 , R 10 , R 11 and R 12 are the same or different groups and each represertts hydrogen or an alkyl group, and two alkyl groups may be attached to one carbon atom on the piperidine ring. When R, is an alkyl group and R a is an unsubstituted aralkyl group, at least one of R 7 , R s , R s , R 10 , R 11 and R 12 represents an alkyl group. Also disclosed are pharmaceutically acceptable acid addition salts of compound (I).
