15.alpha.,16.alpha.-METHYLENE-4-ESTREN-17.beta.-OLS OF THE Formula ##SPC1##Wherein R.sub.1 is lower alkyl, R.sub.2 is hydrogen or an acyl residue, R.sub.3 is hydrogen or a substituted or unsubstituted, saturated or unsaturated monovalent lower aliphatic hydrocarbon, and X is oxygen or the group H,OR.sub.4, wherein R.sub.4 is hydrogen or an acyl residue, have useful anabolic, androgenic, and/or gestagenic activity.
摘要:
16 .alpha.-Alkyl steroids of the formula ##STR1## wherein R.sub.1 is hydrogen or methyl,R.sub.2 is hydrogen, alkyl, acyl, or glycosylR.sub.3 is hydrogen or a substituted or unsubstituted, saturated or unsaturated lower hydrocarbon residue, andR.sub.4 is methyl, ethyl or propyl, exhibit strong progestational activity and a very low androgenic activity.
摘要:
1,3-Dibenzoic acid esters of 17.alpha.-ethynyl-7.alpha.-methyl-1,3,5(10)-estratriene-1,3,17.beta.-triol possess strong estrogenic and ovulation-inhibiting activities. As compared to the corresponding diacetic acid ester, these dibenzoic acid esters remain stable over 2-7 months even in the desired, low dosage at a thermal load of up to 60.degree. C.

摘要:
11.beta.-Fluoroandrostenes of the formula ##SPC1##Wherein R.sub.1 and R.sub.2 are hydrogen atoms, methylene or another C--C bond; R.sub.3 is H or Cl, R.sub.4 is H, F or Cl; and X is carbonyl, .beta.-hydroxymethylene, or an ester or ether thereof or .alpha.-alkyl-.beta.-hydroxymethylene or an ester thereof, possess androgenic activity and can be prepared by the dehalogenation of a corresponding 9.alpha.-halo-11.beta.-F steroid.
摘要:
Steroids of the formula ##STR1## wherein R.sub.1 and R.sub.2 are identical or different and each is hydrogen or the residue of an organic or inorganic acid,and for the esters (R.sub.1 or R.sub.2 is not H) capable of salt formation, the salts thereof, possess valuable pharmacological properties, e.g., good antiandrogenic activity with low progestational activity.
