Definitions

  • This invention relates to nonsteroidal progesterone receptor modulators, a process for their production, the use of progesterone receptor modulators for the production of pharmaceutical agents as well as pharmaceutical compositions that contain these compounds.
  • progesterone regulates the reproductive process in the female organism in a decisive way.
  • progesterone is secreted in large amounts from the ovary or the placenta.
  • progesterone produces cyclic changes of the uterine mucous membrane (endometrium) in the menstrual cycle.
  • the uterine mucous membrane is converted into a state that allows the nidation of an embryo (blastocyte).
  • progesterone controls the relaxation of the myometrium and retains the function of the decidual tissue.
  • progesterone inhibits the endometrial proliferation by the suppression of the estrogen-mediated mitosis in the uterus tissue (K. Chwalisz, R. M. Brenner, U. Fuhrmann, H. Hess-Stumpp, W. Elger, Steroids 65, 2000, 741-751).
  • progesterone and the progesterone receptors are also known in pathophysiological processes. Progesterone receptors are detected in foci of endometriosis, but also in tumors of the uterus, the breast and the CNS. In addition, it is known that uterus leiomyomas grow in a progesterone-dependent manner.
  • progesterone receptor modulators are either pure agonists or partially or completely inhibit the action of progesterone. Consequently, substances are defined as pure agonists, partial agonists (SPRMS) and pure antagonists.
  • progesterone receptor modulators According to the ability of the progesterone receptor modulators to influence the action of the progesterone receptor, these compounds have a considerable potential as therapeutic agents for gynecological and oncological indications as well as for obstetrics and birth control.
  • progesterone receptor antagonists completely inhibit the action of progesterone in the progesterone receptor. They have antiovulatory properties as well as the ability to inhibit estrogen effects in the endometrium up to full atrophy. They are therefore especially suitable for intervening in the female reproductive process, e.g., in post-ovulation, to prevent nidation; in pregnancy, to increase the reactivity of the uterus to prostaglandins or oxytocin or to ensure the opening and softening ("maturation") of the cervix as well as to make the myometrium highly prepared for labor.
  • progesterone receptor antagonist RU 486 also mifepristone
  • the antiglucocorticoidal activity is disadvantageous for a therapeutic application in which the inhibition of the progesterone receptors is a primary focus of therapy.
  • An antiglucocorticoidal activity causes undesirable side effects in the case of therapeutically necessary dosages. This can prevent the application of a therapeutically useful dose or lead to termination of the treatment.
  • the partial or complete reduction of the antiglucocorticoidal properties is therefore an important requirement for the therapy with progesterone receptor antagonists, in particular for those indications that require a treatment lasting weeks or months.
  • progesterone receptor partial agonists show a residual agonistic property, which can be strongly pronounced to different degrees. This leads to the fact that these substances show potential agonistic actions of the progesterone receptor in specific organ systems (D. DeManno, W. Elger, R. Garg, R. Lee, B. Schneider, H. Hess-Stumpp, G. Schuber, K. Chwalisz, Steroids 68, 2003, 1019-1032).
  • organ-specific and dissociated action can be of therapeutic use for the indications described.
  • nonsteroidal progesterone receptor modulators These compounds are to have a reduced antiglucocorticoidal action and are therefore suitable for the therapy and prophylaxis of gynecological diseases such as endometriosis, leiomyomas of the uterus, dysfunctional bleeding and dysmenorrhea.
