摘要:
The present invention relates to the treatment of dementia and neurodegenerative diseases like Alzheimer's disease with intermediate doses of LHRH antagonists which do not cause a castration. A preferred LHRH antagonist is cetrorelix.

Methods for treating sex hormone-dependent conditions are disclosed. The methods of the invention generally feature administration to a subject of an LHRH antagonist, in combination with a second therapy. In one embodiment, this second therapy is the performance of a procedure that removes or destroys tumor tissue, such as radical excision, cryosurgery or radiation therapy (external or interstitial). In another embodiment, the second therapy is treatment with an LHRH agonist, either simultaneously with or subsequent to LHRH antagonist therapy. The methods of the invention can further involve administering an antiandrogen and/or an inhibitor of sex steroid biosynthesis to the subject in combination with the LHRH antagonist. Methods for inhibiting the LHRH antagonist - induced hormone surge, whatever its clinical setting, are also disclosed. These methods generally involve administration of an LHRH antagonist in combination with the LHRH agonist. Complete suppression of the LHRH agonist-induced hormone surge has been achieved by pretreatment with a sustained-released formulation of LHRH antagonist.

Compositions and methods which are effective to inhibit conception and to treat benign gynecological disorders for extended periods of time are described, wherein an effective amount of a gonadotropin hormone releasing hormone composition and an effective amount of an estrogenic composition are provided over a first period of time, in addition to a progestogen and optionally an androgenic composition. According to one protocol, the progestogen is provided for a second, shorter period of time; the progestogen is provided at a higher level for at least 5 to about 20 days, and then at a lower level for the remainder, if any, of the second period of time. In an alternative protocol, the progestogen is provided at a lower level substantially throughout the period of administration of gonadotropin hormone releasing hormone composition and estrogenic composition. An effective amount of the androgenic hormone is optionally provided over the first period of time.
摘要:
Peptides comprenant des acides aminés non naturels et soit inhibant soit favorisant la secrétion de gonadotropines par la glande pituitaire et inhibant la libération de stéroïdes par les gonades. L'administration d'une dose efficace desdits peptides, lesquels sont des antagonistes de GnRH, empêchent l'ovulation d'oeufs de mammifères femelles et/ou la libération de stéroïdes par les gonades. On peut utiliser les antagonistes afin traiter les tumeurs dépendantes de stéroïdes telles que des tumeurs prostatiques et mammaires. Les peptides sont des analogues du décapeptide GnRH, dans lequel se trouve au moins un résidu d'un acide aminé non naturel dans la position 3, la position 5, la position 6 et/ou la position 8. Lesdits acides aminés non naturels sont utiles dans la synthèse de peptide et ont la formule U*, dans laquelle n représente un nombre entier compris entre 1 et 6; Y représente N-CN, N-CONHR9, S, O, ou CH-NO2; R9 représente H, Ac, alkyle inférieur, aromatique ou hétérocyclique; X représente NH, O, S, M1(CHq)pM2 ou M1-(CH2)p'-M2(CH2)p''-M3, où M1 représente NR10, O, S ou CHR3 dans laquelle R3 représente méthyle, éthyle, propyle, phényle, pyridinyle, pyrimidinyle ou purinyle; q représente 1 ou 2; p, p' et p'' représentent des nombres entiers compris entre 0 et 6; R10 représente H, alkyle inférieur ou analogue et M2 ainsi que M3 représentent M1, COOH, CONH2, COOR3 ou CN; R1 représente H, alkyle, alkyle modifié, alcényle, alkynyle, aryle ou une liaison directe à X; R2 représente R1, OH, NH2, NHR1 ou un hétérocycle.
