A drug complex characterized in that a residue of a drug compound such as antineoplastic agents and a carboxy(C
1-4
)alkyldextran polyalcohol obtained by treating a dextran under conditions that enable substantially complete polyalcoholization are bound to each other by means of a spacer comprising an amino acid or a spacer comprising peptide-bonded 2 to 8 amino acids. Said complex is characterized in that it has excellent selectivity to tumorous sites so as to exhibit high antineoplastic activity and also achieves reduced appearance of toxicity.
一种药物复合物,其特征在于将药物化合物(如抗肿瘤剂)的残留物和通过在使得多元醇化反应基本完全的条件下处理
葡聚糖而获得的羧基(C1-4)烷基
葡聚糖多元醇,通过含有
氨基酸的间隔物或者由肽键连接的2至8个
氨基酸组成的间隔物相互结合。该复合物的特点在于具有卓越的对肿瘤部位的选择性,从而表现出高度的抗肿瘤活性,并且能够实现毒性的减少。
