The present invention provides compounds which are esters of a carbohydrate, constituted by a carbohydrate unit or a glycoside derived therefrom, having at least one alcohol group esterified with a branched chain carboxylic acid and having the remaining alcohol groups in part protected with a protector group, such as an isopropylidene group, and partly in the form of free hydroxyls. These carbohydrate esters being provided with a significant biological activity as erythroid cellular differentiation inducers can be utilised for the preparation of a medicament for the therapeutic treatment of β-talaxemia or tumours.
本发明提供的化合物是一种碳水化合物的酯类,由碳水化合物单元或由其衍生的糖苷构成,具有至少一个醇基与支链羧酸酯化,并且其余的醇基部分被保护为保护基团,例如异丙基亚甲基基团,部分以自由羟基的形式存在。这些碳水化合物酯类具有显著的生物活性,可以诱导红细胞分化,可用于制备治疗β-地中海贫血或肿瘤的药物。
