Abstract
Pregnane series steroids are disclosed having good anti-inflammatory and anti-rheumatoid arthritic activity with a decreased degree of side effects, e.g., weight loss and sodium retention. The compounds have the formula ##STR1## where X is a keto- or .beta.-hydroxyl group or chlorine, Y is fluorine or chlorine, Z is hydrogen, .alpha.-hydroxyl, .alpha.-methyl or .beta.-methyl, R' is hydrogen or a 2 to 8 carbon acyl group and R is hydrogen, a 2 to 8 carbon acyl group from mono- or di-carboxylic organic acids, a metasulfobenzoic acid residue or phosphoric acid residue. When R' is hydrogen, and Z is .alpha.-hydroxyl the corresponding 16.alpha., 17.alpha.-acetonides and 16.alpha.-acyl derivatives with organic carboxylic acids having from 2 to 8 carbon atoms were prepared.
