摘要:
The method of prophylaxis and therapy of radical-mediated cell damage includes administering an effective amount of at least one steroid and at least one pharmaceutical adjuvant to a human being. The at least one steroid is selected from the group consisting of ent-estradiol, 17&agr;-estradiol, 8-dehydro-estradiol, 8-dehydro-17&agr;-estradiol, 8(14)-dehydroestradiol, 6,8-didehydro-17&agr;-estradiol, 6-dehydroestriol, 9(11)-dehydroestriol, 20-hydroxymethyl-3-hydroxy-19-norpregna-1,3,5(10)-triene, 14&agr;, 15&agr;-methylene-8-dehydroestradiol, 14&agr;, 15&agr;-methylene-estradiol, 2-hydroxy-estradiol-3-methyl ether, 3-hydroxy-1,3,5(10)-estratriene-17S-spirooxirane, 3-hydroxy-1,3,5(10),9(11)-estratetraene-17S-spirooxirane, and 14&bgr;,15&bgr;-methylene-8-dehydroestradiol. This method strongly inhibits changes in cells and tissues, such as lipid peroxidation and oxidation of low-density lipoprotein (LDL) cholesterol, triggered by reaction oxygen species, free oxygen radicals and other forms of radicals and thus reduces attendant irreversible membrane and endothelial damage.
摘要:
Novel substituted steroid compounds are disclosed which are more effective than known radical-trapping agents in methods of prophylaxis and therapy of radical-mediated cell damage and of treatment of diseases due to radical-mediated cell damage. The novel substituted steroid compounds can be made from steroids having an estrane, androstane, pregnane or cholestane basic skeleton and have a radical-attracting aromatic substituent of the general formula --(CH.sub.2).sub.n X, or .dbd.CH--(CH.sub.2).sub.m X at the 17 or 6 position of the steroid nucleus, wherein X=Y, OY, SY, SeY or NHY; n=0 to 5; m=n-1 and Y is a phenyl group having five substituents A, B, C, D and E, wherein A to E is independently H, alkyl, Oalkyl, Oacyl, OH, or one of the substituents B, C or D is NR.sub.2 wherein R=alkyl and each of the other substituents is hydrogen. Pharmaceutical compositions containing the novel substituted steroid compounds and methods of making them are also part of the invention.
摘要:
Disclosed are estrane derivatives having a radical-attracting aromatic substituent of the general formula --(CH.sub.2).sub.n X attached to the 17-position of the steroid nucleus, wherein X and n are as defined by the specification. The compounds are useful as antitumor agents and in the treatment of cardiac and circulatory disorders.
摘要:
Novel androgens having one or more substituents providing radical trapping properties are disclosed as useful in methods of treating androgen deficiency in man, benign prostate hypotropy and carcinoma of the prostate, osteoporosis, vascular disease-induced or ischemically-induced cerebral edemas, subarachnoid hemorrhages, ischemic shock, cerebral insult, Parkinson's disease and Alzheimer's disease. The androgen compound used for treating androgen deficiency in man has a steroid ring with an .alpha.-tocopherol group or a trolox group substituent.
摘要:
Compounds of the general formula ##STR1## in which R' is hydrogen or a methyl radical; R is a hydroxyl, acetoxy, arylaminocarbonyloxy, alkylaminocarbonyloxy radical;Z is hydrogen or a lower alkyl, orR and Z together are oxygen.These compounds exhibit a very favorable separation of desirable contraceptive and undesirable uterine and antigonadotrophic properties.
摘要:
The 17.alpha.-cyanomethylestra-4,9-diene derivative compounds are of formula I: ##STR1## wherein R.sub.1 is an alkyl group having from 1 to 2 carbon atoms; R.sub.2 is an alkyl group with 1 to 10 carbon atoms, an acyl group with 1 to 10 carbon atoms or a trialkylsilyl group; and R.sub.3 is an oxygen atom or a R--O--N group, wherein R is a hydrogen atom, an acyl group with 1 to 10 carbon atoms, an alkyl group with 1 to 10 carbon atoms, a sulfamoyl group, an alkylsilyl group or a trialkylsilyl group. These compounds, particularly in combination with at least one suitable estrogen, are suitable for treatment of endometrioses or gestagen-dependent tumors and for hormonal contraception and climacteric hormone replacement therapy (HRT). Processes for making the new steroids are described as well as methods of making the pharmaceutical compositions containing them.
摘要:
New gona-4,9(10)-dienes of formula I ##STR1## where R is alkyl of 1 to 3 carbon atoms and X is Cl, Br, F, N.sub.3, SCN, CN, OH, OR'(R'=alkyl), NH.sub.2, a substituted amino group or a heterocyclic compound including nitrogen in the ring. The compounds have valuable biological properties, especially hormonal and antihormonal effects, and can be used to advantage in pharmaceutical preparations for the treatment of endocrinopathies and for reproduction control in human beings and livestock.The invention also embraces a process for making the compounds by converting 3-methyoxy-13.beta.-R-gona-2,5(10)-diene-17.beta.-spiro-1',2'-oxiranes first to 17.beta.-hydroxy-17.alpha.-CH.sub.2 X-13.beta.-R-gon-5(10)-en-3-one, then to the 17.beta.-hydroxy-17.alpha.-CH.sub.2 X-13.beta.-R-gona-4,9(10)-diene-3-ones of formula I.
摘要:
This invention describes 17&agr;-hydroxy-4-androstene-3-one and its derivatives of the general formula I a method for producing these compounds and pharmaceuticals containing these compounds. The compounds according to the invention can be used for regulating spermatogenesis and for hormone replacement therapy in males by stimulating the inhibin-B secretion by the Sertoli cells. The increased inhibin-B concentration suppresses spermatogenesis in the testicles as it inhibits excretion by the hypophysis of follicle-stimulating hormone (FSH) that is essential in spermatogenesis.
摘要:
The pharmaceutical composition, especially for treating skin with seborrhea, Acne vulgaris and androgonically conditioned alopecia, contains a hormonal agent including the gestogen, dienogest, or a combination of dienogest and an estrogen, as active ingredient. Methods for treatment of this type of skin condition include topical application of the composition including the dienogest which results in an outstanding sebosuppression, a drastic reduction of androstandiol glucuronide and a moderate competitive blockage of androgen receptor sites. Galenic formulations are described which limit and/or prevent the permeation of the active ingredient through the skin. The pharmaceutical preparation including the dienogest and conventional dermatologically acceptable carrier and auxiliary substances in the described galenic formulation advantageously provides a drastic reduction in androstandiol glucuronide and moderate androgen receptor blockage without passing through the skin barrier so that systemic effects including side reactions are substantially prevented.
