N-Acyl derivatives of glucosamines made by linking an amino acid or oligopeptide having a m-di(2-chloroethyl)amino-L-phenylalanyl group, to the amino group of the glucosamines by a peptide bond, are endowed with strong anti-tumor action against transplanted neoplasma in animal. The compounds according to the present invention are of the general formula (I): ##STR1## where R.sub.1 is a hydrogen atom or an acetyl group, R.sub.2 is a hydrogen atom, an acetyl group, aliphatic (C.sub.1 -C.sub.6) group or a benzyl group and R.sub.3 is m-di(2-chloroethyl) amino-L-phenylalanine, or L- methionyl -m-di(2-chloroethyl) amino-L-phenylalanyl-p-fluoro-L-phenylalanine, or p-fluoro-L-phenylalanyl-m-di (2-chloroethyl) amino-L-phenylalanyl-L-proline, or m-di (2-chloroethyl) amino-L-phenylalanyl-L-methionyl-p-fluoro-L-phenylalanine. The antineoplasmic activity of the compounds of the present invention is not affected in the gastrointestinal tract and hence they can be effectively administered orally.
通过肽键将含有m-二(2-氯乙基)氨基-L-苯丙氨酰基团的氨基酸或寡肽与葡萄糖胺的氨基基团连接起来制成的葡萄糖胺的N-酰基衍生物,对动物体内移植的肿瘤具有强烈的抗肿瘤作用。本发明的化合物具有以下通式(I):##STR1## 其中R.sub.1是氢原子或乙酰基,R.sub.2是氢原子,乙酰基,脂肪族(C.sub.1-C.sub.6)基或苄基,R.sub.3是m-二(2-氯乙基)氨基-L-苯丙氨酸,或L-甲硫氨酰-m-二(2-氯乙基)氨基-L-苯丙氨酰-p-氟-L-苯丙氨酸,或p-氟-L-苯丙氨酰-m-二(2-氯乙基)氨基-L-苯丙氨酰-L-脯氨酸,或m-二(2-氯乙基)氨基-L-苯丙氨酰-L-甲硫氨酰-p-氟-L-苯丙氨酸。本发明化合物的抗肿瘤活性不受胃肠道影响,因此可以有效地口服给药。
