Definitions

  • the present invention relates to novel compounds based on estrogens and anti-estrogens which are suitable as chemotherapeutic agents for combating tumors, processes for their preparation and their use for the treatment of diseases, in particular cancer.
  • estrogen receptors cytoplasmic proteins
  • the estrogen receptors accumulate in the cancer cells of tumors of the sexual organs, e.g. in mammary tumors and their metastases, particularly strongly (E. v. Angerer, The estrogen receptor as a target for rational drug design, pages 5, 49 and 137, Springer-Verlag, Heidelberg 1995). Attempts have previously been made to use the estrogen receptors as targets for active substances, for example by the natural female sex hormone estradiol or the synthetic diethylstilbestrol with an active group, e.g. associated with a nitrogen mustard function and hoped that the estrogenic base molecule would transport the active group into the tumor and this could then destroy it (G.
  • dialkyltriazenyl group-carrying estrogens and antiostrogens cause their regression after administration to rats with breast tumors.
  • the therapy directed selectively at the breast tumor tissue does not lead to the side effects known from the prior art, e.g. Damage to the bone marrow and intestinal epithelium.
  • Diall ylphenyltriazenes are known as general unselective cytostatic agents; see. Proc. Soc. Exper. Biol. Med. 90: 484 (1955); like alkylating agents (endoxane), they intervene in a targeted manner in the proliferation of all body cells.

  • the advantages of the compounds according to the invention with hydrophilic groups include the fact that they can be accumulated in the cancer cells in the amounts necessary for the therapy due to an excess supply to the estrogen receptors and the excesses can be rapidly eliminated from the body. This minimizes toxic side effects.

  • the estrogenic steroids are an example of how highly specific and highly effective active ingredients can be synthesized from estrogens that bind optimally to the estrogen receptor by introducing a dialkyltriazenyl group. Furthermore, it must be assumed that such active substances are effective against all carcinomas of the sexual organs that contain estrogen receptors (uterus, ovaries, prostate) due to their binding to the estrogen receptor.
