ABSTRACT:
A 3-amino-steroid of the formula ##STR1## wherein W is selected from the group consisting of hydrogen and --OH and taken together with X is ethylidene, X is selected from the group consisting of ethyl, ##STR2## the wavy line indicates the substituent has the .alpha.- and .beta.-position, R.sub.1 is selected from the group consisting of hydrogen and --CH.sub.3, R.sub.2 is selected from the group consisting of hydrogen, alkyl of 1 to 5 carbon atoms and hydroxyalkyl of 2 to 5 carbon atoms, R.sub.3 is selected from the group consisting of hydrogen, alkyl of 1 to 5 carbon atoms, hydroxyalkyl of 2 to 5 carbon atoms, acyl of organic acid of 2 to 8 carbon atoms, alkoxycarbonyl of 2 to 8 carbon atoms, acyl of an .alpha.-amino-carboxylic acid and a peptide of 2 to 3 .alpha.-amino-carboxylic acids and their non-toxic, pharmaceutically acceptable acid addition acids with the proviso that R.sub.2 and R.sub.3 are not both hydrogen and (i) when R.sub.1 is methyl, W and R.sub.2 are hydrogen and X is ##STR3## in the case R.sub.3 is not methyl, acetyl or derived from an anminocarboxylic acid, (ii) when R.sub.1 is --CH.sub.3, W is hydrogen, R.sub.2 is --CH.sub.3 and X is ##STR4## in the case R.sub.3 is not methyl or acetyl, (iii) when R.sub.1 is methyl, R.sub.2 and W are hydrogen, X is ##STR5## with the --OH having the (S) configuration and the amino group is in the .alpha.-position in the case R.sub.3 is not methyl (iiii) R.sub.2 and W are hydrogen, X is ##STR6## and the 3-amino is in the .alpha.-position in the case at least one of R.sub.1, R.sub.2 and R.sub.3 is not methyl and (iiiii) R.sub.2 and W are hydrogen, R.sub.1 is methyl, X is ##STR7## with the --OH having the (R) configuration and the 3-amino is in the .alpha.-position in the case R.sub.3 is not ethoxycarbonyl capable of stimulating the defenses of an organism, especially by potentializing the production of IgE (immunoglobulins E) and their preparation.
