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.
葡萄糖吡喃糖基-硝基脲化合物具有较低的烷基基团和/或2-氯乙基基团作为取代基,在高产率下通过将具有较低烷氧基和/或氨基(或加酸氨基)作为取代基的氨基葡萄糖吡喃糖化合物与具有较低烷基基团或2-氯乙基基团作为取代基的o-硝基或o-氰基苯基N-取代-N-亚硝基氨基甲酸酯化合物反应而产生。包含在硝基脲化合物范围内的1-(较低烷基或2-氯乙基)-3-(D-葡萄糖吡喃糖基-6-基)-1-硝基脲化合物是新颖的。本发明产生的硝基脲化合物均显示抗肿瘤活性,其中新颖化合物展现出优异的物理和药理特性。
