This invention relates to novel allenic prostanoic acid derivatives having the following formula ##STR1## wherein R is hydrogen; or straight or branched chain alkyl of 1 to 6 carbon atoms, inclusive wherein R.sub.1 is hydrogen; or straight or branched chain alkyl of 1 to 6 carbon atoms, inclusive; or vinyl (--CH.dbd.CH.sub.2) wherein R.sub.2 is straight or branched chain alkyl of 1 to 6 carbon atoms; or cycloalkyl group containing 3 to 6 carbon atoms; or phenyl; or phenoxy wherein R.sub.3 is hydrogen; or straight chain alkyl of 1 to 3 carbon atoms wherein m is an integer of from 1 to 4, inclusive, wherein n is an integer of from 1 to 3, inclusive with the proviso that the sum of m and n does not exceed 5, wherein y is an integer of from 1 to 3. These compounds are useful by reason of their gastric antisecretory and cytoprotective activity.
这项发明涉及具有以下结构的新型亚烯基前列腺酸衍生物,其中R为氢;或1至6个碳原子的直链或支链烷基,其中R₁为氢;或1至6个碳原子的直链或支链烷基;或乙烯基(--CH=CH₂),其中R₂为1至6个碳原子的直链或支链烷基;或含有3至6个碳原子的环烷基团;或苯基;或苯氧基,其中R₃为氢;或1至3个碳原子的直链烷基,其中m为1至4之间的整数,其中n为1至3之间的整数,但m和n的总和不超过5,其中y为1至3之间的整数。这些化合物由于其胃抗分泌和细胞保护活性而具有用途。
