The compounds have the formula I (FORMULA) wherein R<u1>u is H, a C<u1-4>u alkyl or their precursors, R<u2>u is a C<u1-4>u alkyl, R<u3>u and R<u4>u independently of each other are H, a C alkyl or together are a C alkylene, R<u5>u is H or alkyl and A and B are each H or together represent a bond, providing that, when R<u1>u and R<u2>u = CH<u3>u, R<u3>u and R<u4>u = C<u2>uH<u5>u, A and B = H, R<u5>u is alkyl. Are also concerned the acid addition salts of those compounds. The compounds are used for the treatment of hypertonus, and cardiac insufficiencies. |
