The synthesis of the pure diastereoisomer of 16-methoxy-16-methyl-PGF2 alpha, -PGE2, and -PGE1 is described. The absolute configuration of C-16 was established by chemical methods, while the absolute C-15 configurations of the diastereoisomers were assigned tentatively on the basis of their chromatographic behavior and NMR spectra. The synthetic prostaglandin analogues were evaluated for antisecretory
描述了16-甲氧基-16-甲基-PGF2α,-PGE2和-PGE1的纯非对映异构体的合成。C-16的绝对构型通过化学方法确定,而非对映异构体的绝对C-15构型根据其色谱行为和NMR光谱暂定。评价合成的前列腺素类似物的抗分泌,抗生育和腹泻作用。发现C-15和C-16构型对于生物活性都是至关重要的。这些研究表明,将C-16处的甲基和甲氧基引入到前列腺素类似物中明显增加了抗分泌与腹泻作用的比率。PGE1衍生物之一9f(15 alpha,16R)(MDL646 mexiprostil),
