Abstract
Certain 16.beta.-methyl-3-oxoandrost-4-ene and 16.beta.-methyl-3-oxoandrosta-1,4-diene 17.beta.-thiocarboxylic acid esters are useful as anti-inflammatory steroids. These compounds are optionally substituted at the 6.alpha.-position with fluoro or chloro; optionally substituted at the 9.alpha. position with fluoro, chloro or bromo; substituted at the 11 position with a keto, a .beta.-hydroxy or a .beta.-chloro (the latter only when there is a 9.alpha.-chloro); and substituted with 17.alpha.-hydroxy (or an ester thereof).
