Abstract
The invention relates to decapeptide derivative which has LHRH receptor antagonism activity, an effect of inhibiting pituitary to excrete gonadotrophic hormone, an effect of inhibiting the gonad to excrete steroid hormone and has a lower histamine releasing effect, its producing method, the drug combination and its drug applications for treating the sex hormone correlated disease such as prostate cancer and the disease correlated to the anti-histamine or reducing histamine release.
Description
Technical field
The present invention relates to the decapeptide derivative that has the LHRH receptor antagonist activity and have lower histamine release side effect, contain their pharmaceutical composition and the described decapeptide derivative purposes that relies on the medicine of relative disease for the preparation for the treatment of prostate cancer and other sexual hormoue.
Background technology
LHRH (luteinizing hormone-releasing hormone) is by one of peptide hormone of hypothalamus secretion, its Main Function is to promote that hypophysis is synthetic and discharge lutropin (LH) and follicular stimulating hormone (FSH), excites Development in Puberty and regulates reproduction, fertility and sexual hormoue correlated process.LHRH is comprised of ten amino-acid residues, and the C-end contains amide structure.The primary structure of LHRH is as follows:
p-Glu-His-Trp-Ser-Tyr-Gly-Leu-Arg-Pro-Gly-NH
2
Lhrh antagonist is by the release of blocking-up LHRH effect and then inhibition LH, therefore can be used for the treatment of the diseases such as sexual hormoue associated cancer such as prostate cancer, existing unique lhrh antagonist class medicine that has gone on the market is cetrorelix (Cetrorelix), is mainly used to control ovary excitement and LH fluctuation.Compare with agonist, lhrh antagonist have produce effects speed fast, without recover after upper punch phenomenon, the drug withdrawal fast, to advantages such as the horizontal controllability of serum androgen are strong.Can expect, the curative effect of lhrh antagonist treatment prostate cancer is better than agonist, is easilier accepted by the patient, has the application prospect larger than agonist.
Histamine is a kind of inflammatory mediator of finding the earliest, by generating after the l-histidine decarboxylation for extensively being present in a kind of autacoid in the tissue.Major storage was in the particle of mastocyte and basophilic granulocyte after histamine generated, and transformation reactions or other materializations stimulate and impel mast cell degranulation, discharge histamine.Histamine can cause transformation reactions in vivo, and the generation of many inflammation is all relevant therewith.Its tip that can excite nerve causes skin rubefaction and itch; Can make the smooth muscle contraction of Various Tissues, especially bronchial smooth muscle causes bronchial asthma; Also can cause the arteriole diastole, cause the contrafluxion oedema, suffer a shock when serious.
Most drug more or less can cause the side reaction of histamine release in vivo, thereby the lhrh antagonist of exploitation is exactly can cause anaphylactoid generation owing to can cause excessive histamine release at present, therefore fails clinically well to be used.So, keeping on the basis of greater activity, how further modifying lhrh antagonist just becomes a important step in the lhrh antagonist drug research to falling its low histamine release effect.
Before this, the inventor has had been found that some have the long-acting antagonist of LHRH receptor antagonist activity (referring to Chinese patent application No.200510115056.2).Purpose of the present invention then is on the basis of original long-acting lhrh antagonist, further seeks the lhrh antagonist with lower histamine release effect.
Summary of the invention
The inventor has now found that to have the decapeptide derivative of following formula (I) through research:
R-β-D-Nal-D-Cpa-Xaa
3-Ser-Xaa
5-Xaa
6-Leu-Xaa
8-Pro-D-Ala-B
Formula (I)
Or its steric isomer or physiologically acceptable salt are when having good LHRH antagonistic activity, also have lower histamine release side effect, so formula (I) decapeptide derivative or its steric isomer or physiologically acceptable salt can be used as medicine and are used for the treatment that prostate cancer and other sexual hormoue rely on relative disease.
Therefore, first aspect of the present invention relates to formula (I) decapeptide derivative or its steric isomer or physiologically acceptable salt,
