Abstract:
The invention relates to 17 alpha fluoroalkyl steroids of the general formula (I), STEROID (I), wherein R3 represents a group of the formula CnFmHo, wherein n = 1, 2, 3, 4, 5 or 6, m > 1 and m+o = 2n+1. The invention further relates to methods for producing the same and to compositions that contain said compounds. The inventive composition of the general formula (I) possess androgenic activity.
Abstract:
New non-estrogenic estradiol derivatives with an antioxidant effect are disclosed. These estradiol derivatives, which have no estrogenic effect but a high antioxidant effect, are potentially useful as non-estrogenic antioxidants, in particular for postmenopausal women and for men. Moreover, the disclosed compounds are potential aromatase and sulfatase inhibitors.
Abstract:
Novel antiandrogenic agents are provided. An exemplary group of compounds has the structural formula (I), wherein R through R , a and b are as defined herein. Pharmaceutical compositions and methods for using the compounds of formula (I) to treat androgen-related clinical conditions are provided, as are methods and compositions for using the compounds as contraceptive agents.
Abstract:
The invention relates to 17α-(5-hydroxy-C 5 -hydrocarbyl)-l,3,5(10)-estratrien-3,17β-diol derivatives having cicatrising activity, preferably for topical use on wounds, without significant systemic effects, and to pharmaceutical compositions containing them. In particular, the invention relates to estradiol 17α-(5-hydroxypentyn-l-yl)derivatives and 3-esters, 5'-esters and 3,5'-diesters thereof and to a process for the preparation thereof by reaction of 3-OR-protected estrone with an alkali metal derivative of OR-protected 5-pentynol, followed by 3-, 5-' or 3,5'-esterifÊcation.
Abstract:
The invention relates to a method for the production of 4-(17 -methyl substituted 3-oxoestra-4,9-dien-11 -yl)benzaldehyd-(1E or 1Z)-oximes of general formula (I), where R1 = H, C1-6 alkyl or a CnF2n+1 group, where n = 1, 2 or 3; R2 = C1-4 alkyl, X = E- or Z-OH; and Y = O-C1-6 alkyl, S-C1-6 alkyl or O-CH2CnF2n+1, where n = 1, 2 or 3, which produces the target compounds of formula (I) with high yield and selectivity.
Abstract:
Inhibitors of sex steroid activity, for example those having general structure (A) may be used as part of a pharmaceutical composition to provide antiestrogenic effects and/or to suppress estrogen synthesis. Such pharmaceutical compositions are useful for the treatment of breast cancer or other diseases whose progress is aided by activation of sex steroid receptors.
Abstract:
The invention relates to 17-hydroxy-17-pentafluorethyl-estra-4,9(10)-dien-11-ethyinylphenyl derivatives of formula (I), wherein Y and X are defined as in the claims and in the description, to a method for the production thereof and to the use thereof as medicaments.
Abstract:
Beschrieben wird ein Verfahren zum Herstellen von Kristallen von Steroiden, deren durchschnittliche Partikelgrösse in einem vorgegebenen Bereich liegen and deren maximale Partikelgrösse einen vorgegebenen Wert nicht überschreiten, wobei eine übersättigte Lösung der Steroide, während der Kristallisation einem Nassmahlen mittels einer Vorrichtung zum Nassmahlen unterzogen wird, wodurch eine Primärkornsuspension erhalten wird.
