摘要:
17-methylene-4-azasteroid compounds of formula I: wherein R20 denotes fluoro, chloro or bromo R20a denotes hydrogen, R10 and R4 each denote a hydrogen atom or a methyl group, and R1 and R2 each denote a hydrogen atom or together denote an additional bond, are useful for treating diseases or conditions caused by excessive androgen levels, such as acne, prostate diseases, alopecia and hirsutism, as well as gynecological conditions. Methods of synthesizing the new 17-methylene-4-azasteroid compounds are described.

摘要:
A face seal device for use with components rotating at a high rotational speed includes a non-rotating face seal ring (5) and a rotary face seal ring (11). The rotary face seal ring is mounted in a loose fit for common rotation with a rotating component and includes a sealing face (6) which, in operation, is essentially radially aligned for cooperation with an opposite sealing face (16) of the non-rotating face seal ring. A heavy-mass-contributing element (22) is arranged to rotate in common with the rotating component and engages a portion of the rotary face seal ring. The center of gravity of the heavy-mass-contributing element is axially spaced from that of the rotary face seal ring, whereby, in operation, a torque directed towards the non-rotating face seal ring is applied to the rotary face seal ring. This torque arises from the centrifugal forces that correspond to the mass-contributing element and the spacing between the centers of gravity.

The present invention describes non-steroidal compounds of the general formula (I) in which A is in which X1 means one or more groups on the phenyl ring and represents independently of one another a halogen, OH, (C1-C4)alkyl, (C1-C4)alkyl-O, (C3-C6)cycloalkyl-O, (C1-C14)acyl-O, (C1-C4)alkenyl, (C1-C4)alkynyl, perfluoro(C1-C4)alkyl radical, —CHO or CN, and X2 means one or more groups on the phenyl ring and represents independently of one another an H, halogen, OH, (C1-C4)alkyl, (C1-C4)alkyl-O, (C1-C4)alkenyl, (C1-C4)alkynyl, perfluoro-(C1-C4)alkyl radical, —CHO or CN, as Estrogens.
摘要:
New 17α-fluorosteroid compounds of formula (I) are disclosed: wherein R1 denotes H or methyl; R2 and R3 each denote H, Cl or methyl; and either a double bond or a single bond is present between C-6 and C-7 and also C-9 and C-10 of the steroid ring system respectively. These compounds have an activity profile with hybrid character so that they act as inhibitors for 5α-reductase and as high potency gestagens. Pharmaceutical compositions containing them are disclosed. They are suitable for treatment of conditions, which are caused by high levels of androgen in organs and tissues. These new compounds can be used in combination with other hormonal substances, such as estrogens, testosterone and other androgens, as contraceptives and for other applications.
摘要:
This invention provides estriol and estetrol prodrugs of general formula (I), in which group Y is bonded to the steroid process for their production, pharmaceutical compositions that contain these compounds, as well as their use for the production of pharmaceutical agents with estrogenic action.
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.
