    • The invention relates to new 16-amino-18,19,20-trinor-prostaglandin derivatives of general formula I, having at C-17 a substituted or unsubstituted phenyl group, wherein C-15 and C-16 may have either S or R configuration, Y stands for a hydrogen atom or a lower alkyl group, W stands for a hydrogen atom, halogen atom, hydroxy group, lower alkyl or alkoxy group, and their acid addition salts. These compounds can be prepared by removing the ester group and the p-nitrobenzyloxycarbonyl protective group of a 9.alpha.,11.alpha.,15-trihydroxy-16-p-nitrobenzyloxycarbonylamido-17-phenyl-5-cis,13-trans-18,19,20-trinor-prostadienoic acid derivative of general formula XII--wherein C-15 and C-16 may have either S or R configuration, W is as defined above, and Y stands for a lower alkyl group--in an optional sequence with the limitation that in those compounds of general formula I where W is as defined above and Y stands for a lower alkyl group, solely the p-nitrobenzyloxycarbonyl 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 in cattle raising for estrus and birth synchronization, furthermore in the veterinary praxis for the treatment of sterility, chronic endometritis and pyometry.
    • 本发明涉及具有C-17取代或未取代的苯基的通式I的新的16-氨基-18,19,20-三核 - 前列腺素衍生物,其中C-15和C-16可具有S或R 构型中,Y表示氢原子或低级烷基,W表示氢原子,卤素原子,羟基,低级烷基或烷氧基,以及它们的酸加成盐。 这些化合物可以通过除去9α,11α,15-三羟基-16-对硝基苄氧羰基酰胺基-17-苯基-5-顺式,13-trn-18的酯基和对硝基苄氧羰基保护基来制备, 其中C-15和C-16可以具有S或R构型,W如上所定义,Y代表低级烷基 - 在任选的序列中,具有通式XII-的19,20-三过 - 前列腺素酸衍生物 - 在通式I的那些化合物中的限制,其中W如上所定义,Y代表低级烷基,仅除去对硝基苄氧基羰基,所得到的通式I的产物任选地用有机或无机 酸变成盐。 本发明的新型前列腺素衍生物具有有价值的治疗特性,可用于发情期和出生同步的养牛,此外还适用于无菌治疗,慢性子宫内膜炎和高血压的兽医学应用。
