Abstract
The invention relates to new 16-amino-prostaglandin derivatives of general formula I, ##STR1## wherein C-15 and C-16 may have either S or R configuration, Z stands for a hydrogen atom or a lower alkyl group, and their acid addition salts. These compounds can be prepared by removing the ester group and the p-nitrocarbobenzyloxy protective group of a 9.alpha., 11.alpha., 15-trihydroxy-16-p-nitrobenzyloxycarbonylamido-5-cis,13-trans-prostadienoi c acid derivative of general formula XII--wherein C-15 and C-16 may have either S or R configuration and Z stands for a lower alkyl group--in an optional sequence with the limitation that in those compounds of general formula I where Z stands for a lower alkyl group solely the p-nitrocarbobenzyloxy group is removed, and the resulting product of general formula I is optionally converted with an organic or inorganic acid into a salt. The new prostaglandin derivatives of the invention have valuable therapeutical properties, and can be applied as abortive or oxytocic agents.
