The specification describes a nitrosourea derivative having the general formula: Cl--(CH.sub.2).sub.2 --N(NO)CO--NHR, wherein --NHR represents a 2-(1,3,4-thiadiazolyl)amino group, an amino residue of a neutral .alpha.-amino acid, or an amino residue of a neutral .alpha.-amino acid whose carboxyl group is amidated with 2-(1,3,4-thiadiazolyl)amine, or a pharmaceutically acceptable acid addition salt thereof. The above nitrosourea derivative and its salt are useful as antitumor drugs. The above nitrosourea derivative may be prepared either by nitrosating a urea derivative of the general formula: Cl--(CH.sub.2).sub.2 NHCONHR or by reacting N-(2-chloroethyl)-N-nitrosocarbamic acid or a reactive derivative thereof with an amino compound of the general formula: R--NH.sub.2.
该规格说明书描述了一种亚硝基脲衍生物,其一般式为:Cl--(CH.sub.2).sub.2 --N(NO)CO--NHR,其中--NHR表示2-(1,3,4-噻二唑基)氨基基团,中性α-氨基酸的氨基残基,或其羧基被2-(1,3,4-噻二唑基)胺酰化的中性α-氨基酸的氨基残基,或其药物可接受的酸盐。上述亚硝基脲衍生物及其盐可用作抗肿瘤药物。上述亚硝基脲衍生物可通过亚硝化一般式为Cl--(CH.sub.2).sub.2 NHCONHR的脲衍生物或通过反应N-(2-氯乙基)-N-亚硝基氨基甲酸或其活性衍生物与一般式为R--NH.sub.2的氨基化合物制备。
