Pregnane-21-oic acid derivatives of the formula ##STR1## wherein THE LINKAGE REPRESENTS A SINGLE BOND OR A DOUBLE BOND;X is hydrogen, fluorine or chlorine;Y is methylene, hydroxymethylene, alkanoyloxymethylene, carbonyl, fluoromethylene or chloromethylene;R.sub.1 is hydrogen, alkyl of 1-6 carbon atoms, phenyl or naphthyl substituted with 0-3 lower alkyl, lower alkoxy or chlorine; andR.sub.2 represents a hydrogen atom, the cation of a physiologically compatible base or the residue of a physiologically acceptable alcohol of 1-18 carbon atoms.These compounds exhibit useful antiinflammatory activity when topically applied to inflamed skin.
摘要:
Glucocorticoids of general formula IR--Val--O--GC (II),are described,in whichO-GC is the radical of a 21-hydroxycorticoid that has an antiinflammatory action,Val represents a valine radical in the 21-position of the corticoid andR means a hydrogen atom or a hydrocarbon radical with up to 32 carbon atoms that is optionally substituted by hydroxy groups, amino groups, oxo groups and/or halogen atoms and/or interrupted by oxygen atoms, SO.sub.2 groups and/or NH groups and their salts.
摘要:
6.alpha.,16.alpha.-Dimethyl corticoids of general Formula I ##STR1## wherein the bond is a single bond or a double bond,X is a hydrogen atom, a fluorine atom, a chlorine atom, or a bromine atom,R.sub.1 is a formyl group, an alkanoyl group or alkoxyalkyl group of 2-8 carbon atoms, or a benzoyl group, andY is a hydrogen atom, a chlorine atom, a hydroxy group, a formyl group, an alkanoyloxy group of 2-8 carbon atoms, or a benzoyloxy group,are pharmacologically effective compounds.
摘要:
Compounds of the formula ##STR1## wherein X is .beta.-CH.sub.2 OH or CO and R.sub.2 is F, Cl or CH.sub.3, and their physiologically acceptable 21-esters are useful for the treatment of allergic diseases of the respiratory tract and for the treatment of topical and systemic inflammatory conditions.
摘要:
3,17,18-Trihydroxy-1,3,5(10)-estratrienes of the formula ##SPC1##Wherein R is H or substituted or unsubstituted saturated or unsaturated hydrocarbon, and esters and ethers thereof, possess strong vaginotropic and only weak utertropic activity and are useful in the treatment of estrogenic deficiency conditions where uteral effects are not desired.
摘要:
Pharmaceutical preparations for the local treatment of inflammations are claimed herein, characterized in that they contain as the active ingredient one or two compounds of general Formula I ##STR1## wherein X is an oxygen atom or a methylene group, R.sub.1 and R.sub.2 represent a hydrogen atom or a hydrocarbon residue of maximally eight carbon atoms, optionally interrupted by an oxygen atom, R.sub.3 is a hydrogen atom or a hydrocarbon residue of maximally eight carbon atoms, optionally substituted by an oxo group, and R.sub.4 is a hydrogen atom or an alkyl group of maximally four carbon atoms.
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.
