The invention includes compounds of formula (I): ##STR1## in which R.sup.1 is hydrogen, alkyl, aryl-substituted alkyl or aromatic heterocyclic-substituted alkyl; R.sup.2 is aryl-substituted alkyl, aromatic heterocyclic-substituted alkyl or diarylamino; and R.sup.3 is carboxy or a group of formula --CONHSO.sub.2 R.sup.4 wherein R.sup.4 is alkyl; and pharmaceutically acceptable salts and esters of the compounds. The compounds have valuable 5.alpha.-reductase inhibitory activity and can thus be used for the treatment and prophylaxis of, inter alia, prostatic hypertrophy as well as other disorders arising from excess levels of 5.alpha.-dihydro-testosterone.
The invented compound ##STR1## is useful for the production of steroidal-17-amides that have 5.alpha.-reductase inhibitory activity.
