Glucopyranose-nitrosourea compounds having lower alkyl group and/or 2-chloroethyl group as substituent(s), are produced at high yield by reacting amino-glucopyranose compounds having lower alkoxy group and/or amino group(s) (or an acid-added amino group) as substituent(s), with o-nitro- or o-cyano-phenyl N-substituted-N-nitrosocarbamate compounds having lower alkyl group or 2-chloroethyl group as substituent. 1-(Lower alkyl or 2-chloroethyl)-3-(D-glucopyranos-6-yl)-1-nitrosourea compounds included within the scope of the nitrosourea compounds are novel. The nitrosourea compounds produced by this invention all show antitumor activity, among which the novel compounds exhibit excellent physical and pharmacological properties.
New nitrosourea derivatives are provided, which possess a high inhibitory activity against the leukemia and tumors with a low toxicity and which are useful for pharmaceutical purposes. The compounds have the formula ##STR1## wherein A represents a glycosyl group, a monovalent residue of methyl glucoside or of alditol, a N-substituted carbamoyloxyalkyl group or a hydroxy-substituted cyclohexyl group when n is 1, or A represents a tetravalent residue of ribostamycin when n is 4 and R represents a lower alkyl or halo-alkyl group and are prepared by treating a compound of the formula ##STR2## with a nitrosating agent.
