  Meiosis activating sterols derived from diosgenin

  摘要：

  Continuing research based on the meiosis activation properties of the endogenous sterol FF-MAS is reported. The synthesis and SAR of 16- and 26-substituted sterols are described, utilising diosgenin as starting material. Selected sterols were tested for their ability to induce oocyte maturation in hypoxanthine arrested mouse oocytes in vitro. (C) 2002 Elsevier Science Ltd. All rights reserved.

  Sterol derivative compounds, structurally related to natural compounds which can be extracted from bull testes and from human follicular fluid, useful for regulating meiosis in oocytes and in male germ cells. Some of these compounds are useful in the treatment of infertility, whereas other compounds are useful as contraceptives.

  甾醇衍生物化合物，结构上与可以从公牛睾丸和人类卵泡液中提取的天然化合物相关，对调节卵母细胞和男性生殖细胞中的减数分裂有用。其中一些化合物对治疗不孕症有用，而其他化合物则可用作避孕药。
