摘要:
This invention is concerned with novel 21-phosphate esters of 17 Alpha -acyloxy-21-hydroxy steroids of the pregane series and with methods of preparing such compounds. The compounds are useful as topical anti-inflamatory agents.
WHEREIN R1 REPRESENTS AN ALKANOYL GROUP CONTAINING 3 OR 4 CARBON ATOMS, AND R2 REPRESENTS A HYDROGEN ATOM OR AN ALKANOYL GROUP CONTAINING 2, 3 OR 4 CARBON ATOMS.
摘要:
The Specification describes compounds of the general formula WHEREIN X represents a hydrogen, chlorine or fluorine atom; R1 represents a Beta -hydroxy group, an oxo group or (when X is a chlorine atom) a Beta -chlorine atom; R2 represents a hydrogen atom, a methylene group or an Alpha or Beta -methyl group; R3 represents a hydrogen atom or C1-4alkyl or phenyl group; R4 represents a methyl group substituted by at least one halogen atom; an ethyl group substituted by at least one fluorine and/or iodine atom; or a propyl group substituted by at least one halogen atom; and represents a single or double bond. The Specification also describes processes for the preparation of compounds of formula I as well as pharmaceutical compositions containing such compounds. The compounds of formula I have good anti-inflammatory activity, particularly on topical application.
摘要:
THE SPECIFICATION DESCRIBES NEW ANDROSTANE COMPOUNDS HAVING ANTI-INFLAMMATORY ACTIVITY. THE NEW ANDROSTANCES DESCRIBED IN THE SPECIFICATION HAVE AN ESTERFIELD 17B-CARBOXYLICC ACID GROUPING WHEREIN THE ALCOHOL RESIDUE COMPRISES EITHER AT LEAST ONE HALOGEN ATOM OR A LOWER ALKOXYBY EITHER AT LEAST ONE HALOGEN ATOM OR A LOWER ALKOXYCARBONYL GROUP OR A (C2-4) LOWER ALKYL GROUP SUBSTITUTED BY A LOWER ACYLOXY GROUP. THE 17A-GROUPING OF THESE ANDROSTANCES IS AN ESTERIFIED HYDROXY GROUP COMPRISING A FORMLY, C2-4 ALKANOYL OR BENZOYL GROUP.
WHEREIN R1 IS A FLUORINE, CHLORINE, BROMINE OR IODINE ATOM, R2 IS AN ALKANOXY GROUP CONTAINING 1-4 CARBON ATOMS, R3 IS AN ALKYL GROUP CONTAINING 1-4 CARBON ATOMS OR A METHYLENE GROUP (=CH2), X IS A HYDROXY GROUP IN THE B-CONFIGURATION OR A KETO GROUP, Y IS A FLUORINE OR CHLORINE ATOM, AND = REPRESENTS A SINGLE OR DOUBLE BOND BETWEEN THE 1AND 2-POSITIONS OF THE MOLECULE.
