A 14.alpha.,17.alpha.-bridged estratriene of formula I ##STR1## wherein (a) OR.sup.3 is in .alpha.-positionR.sup.1, R.sup.2 and R.sup.3, each independently are (i) hydrogen, (ii) ##STR2## in which R.sup.4 is an organic radical with up to 11 carbon atoms or (iii) --(CH.sub.2).sub.n COOH wherein n=1-4, or (iv) R.sup.1 is a benzyl, C.sub.1 -C.sub.8 alkyl or C.sub.3 -C.sub.5 cycloalkyl, or(b) OR.sup.3 is in .beta.-positionR.sup.1, R.sup.2 and R.sup.3, each independently are (i) hydrogen, (ii) an acyl group with 1 to 12 carbon atoms or (iii) R.sup.1 is C.sub.1 -C.sub.8 alkyl, and in both (a) and (b) A--B is an etheno or ethano bridge.
摘要:
The new 14.alpha.,16.alpha.-ethano- and 14.alpha.,16.alpha.-etheno-estratrienes of general formula I, ##STR1## are described, in which A-B means a C-C single bond or C-C double bond,R.sub.1 means a hydrogen atom, a methyl or acyl group with 1-12 carbon atoms andX means oxygen or ##STR2## in which R.sub.2 represents a hydrogen atom or an acyl group with 1-12 carbon atoms,and a process for their production. The new compounds are very strong estrogens and are suitable for the production of pharmaceutical agents.
摘要:
Corticoid 21-sulfopropionates of the formula ##STR1## wherein St is a steroid nucleus of a corticoid having anti-inflammatory activity,and the salts thereof with physiologically acceptable bases, simultaneously form stable, sterilizable and storable solutions and also are very rapidly cleaved after i.v. administration, yielding the free corticoids as the cleavage product.
摘要:
A 18-Methyl-19-nor-17-pregn-4-ene-21,17-carbolactone of general formula I in which Z, R4, R6, R7 are as defined below with the proviso that the compound is not 18-Methyl-15β,16β-methylene-3-oxo-19-nor-17-pregn-4-ene-21,17-carbolactone.
摘要:
This invention describes the new 18-nor steroids (gonatrienes) of general formula (I), in which R1, R2, R3, R6, R7, R8, R9, R11, R11′, R14, R15, R15, R16, R17 and R17′ have the meanings that are indicated in the description, as pharmaceutical active ingredients that have in vitro a higher affinity to estrogen receptor preparations of rat prostates than to estrogen receptor preparations of rat uteri and in vivo a preferential action on bone in comparison to the uterus, and/or pronounced action relative to the stimulation of the expression of 5HT2a-receptors and transporters, their production, their therapeutic use and pharmaceutical dispensing forms that contain the new compounds. The invention further describes the use of steroids, on which the gonatriene skeleton is based, for treatment of estrogen-deficiency-induced diseases and conditions as well as the use of the gonatriene structural part in the total structures of compounds that have a dissociation in favor of their estrogenic action on bone in comparison to the uterus.
