Definitions

  • the invention relates to estradiol prodrugs of the general formula I
  • Estrogens play an important role in both sexes in the organism. Estrogens are involved in the formation of gender characteristics in the maturing organism. In both sexes, estrogens control the changes in the organism during sexual maturation, such as the growth spurt and then the stopping of bone growth. In all phases of life, estrogens play a central role in both sexes in bone metabolism (1) . Their loss leads to the breakdown of bone substance and carries the risk of increased brittleness of the bone.
  • estrogens secreted by the ovary dominate in the organism.
  • the placenta produces large amounts of estrogen during pregnancy.
  • estrogens predominantly arise "peripherally” through the aromatization of testosterone or the adrenal androgens in various success organs, such as the CNS, the bones or the intestinal epithelium. This adaptation allows the physiological estrogen effects in men with very low estradiol levels in the blood.
  • men and women with a genetic defect of the aromatase or the estrogen receptor the bones are massively disturbed in terms of growth and maintenance ⁇ 2) .
  • the natural estrogens When administered orally, the natural estrogens have a low oral bioavailability (3) .
  • Natural estrogens have been modified to improve oral bioavailability.
  • Conventional chemically modified estrogens with improved Bioavailability e.g. B. ethinylestradiol, often have another disadvantage, namely a significantly increased estrogen effect in the liver () .
  • This hepatic estrogenicity affects a number of functions, such as transport proteins, fat metabolism, blood pressure regulation and coagulation factors (5) .
