Abstract

New steroids and amides of formula I are described, in which the variables are defined by the description. Relative to the basic hydroxy compounds (“initial compounds”), the new compounds are distinguished by a considerably improved solubility and partially also by increased biological action and selectivity. The new compounds are suitable for the production of pharmaceutical agents.
