The invention relates to the preparation of unsymmetrically 1,3-disubstituted nitroso ureas from the corresponding N-substituted alkyl-N-nitrosocarbamoyl azide which is reacted with an amine, a diamine, an aminoalcohol, an aminoacid or an aminoacid derivative. The N-nitrosocarbamoyl azide is obtained by reacting the corresponding alkylcarbamoyl azide with nitrogen tetroxide in the cold. The alkylcarbamoyl azide is obtained by reacting the corresponding isocyanate with an alkali metal azide. The invention further relates to novel nitroso ureas obtained thereby, to novel N-substituted alkyl-N-nitrosocarbamoyl azides, and to novel therapeutic compositions containing, as the active ingredient, the novel nitroso ureas.

Four steroidal nitrosoureas with structures which may permit specific binding to estrogen receptor were synthesized. Inhibitory activity was observed against the growth of the DMBA-induced transplantable rat mammary tumor 13762.
The invention relates to the preparation of novel N-substituted alkyl-N-nitrosocarbamoyl azides and to the compounds obtained thereby. The novel N-substituted alkyl-N-nitrosocarbamoyl azides can be reacted with amines, diamines, aminoalcohols, aminoacids or aminoacid derivatives to prepare unsymmetrically 1,3-disubstituted nitrosoureas which show therapeutical activity.
