In view of the finding that 5α-pregnane-3β, 5, 6β, 16β, 20α-pentol (POL) shows an interesting sodium excreting activity similar to that of SEF in the animal test, a number of polyoxygenated pregnanes possessing the hydroxyl or the carbonyl groups at the positions of C-3, C-5, C-6, C-16, and C-20 were synthesized. Syntheses of 3β, 5, 6β, 16α-tetrahydroxy-5α-pregnan-20-one-a hybrid compound of POL and SEF-was also described.
考虑到5α-孕烯-3β, 5, 6β, 16β, 20α-五醇(POL)在动物实验中表现出与
SEF相似的有趣的排
钠活性,合成了一些在C-3、C-5、C-6、C-16和C-20位上具有羟基或羰基的多氧化孕烷化合物。同时还描述了3β, 5, 6β, 16α-四羟基-5α-孕烯-20-酮的合成,这是一种POL和
SEF的杂合化合物。
