The synthesis and gastric antisecretory activities of the delta 4,5-cis, delta 4,5-trans, and 4,5-acetylenic analogues of 15-deoxy-16-hydroxy-16-methyl prostaglandin E1 methyl ester are described. The key step in the preparation of these compounds involved the stereospecific conjugate addition of a cuprate reagent to the appropriate cyclopentenones. Although the trans and acetylenic derivatives were
描述了15-脱氧-16-羟基-16-甲基前列腺素E1甲酯的δ4,5-顺式,δ4,5-反式和4,5-炔属类似物的合成和胃抗分泌活性。制备这些化合物的关键步骤涉及向适当的环戊烯酮中立体定向共轭添加铜酸盐试剂。尽管反式和炔属衍生物是胃酸分泌的弱抑制剂,但顺式烯烃比饱和母体化合物更有效且作用时间更长。发现相对于母体16-羟基化合物和参考标准品(15S)-15-甲基-和16,16-二甲基前列腺素E2的选择性而言,相对于不需要的腹泻作用的选择性得到了改善。
