Synthesis and activities of antitumor agents

N-(2-Chloroethyl)-N-nitrosocarbamoyl derivatives of glycosylamines have been prepared. Six N-(2-chloroethyl)-N-nitrosoureas, including three disaccharide derivatives, were submitted to a determination of antitumor activity. All the compounds tested exhibited strong antitumor activity against leukemia L1210 in mice.
