spans of mice bearing mammary carcinoma were obtained by treatment with the N6-allyl, N6-isopropyl, and N6-propargyl analogues, respectively. In rats, the N6-allyl analogue slowed the rate of transplantable mammary tumor growth by one-fourth. The short-chain adenosine analogues are more active in the treatment of animal carcinomas than in the leukemia or sarcoma tumor cell systems.
化合物N6-烯丙基-,N6-异丙基-,N6-炔丙基-和N6-(2-甲基烯丙基)
腺苷是通过使
6-氯嘌呤核糖核苷与过量的相应胺在
乙醇中,在两种酸存在下反应制备的受体几乎产生定量的产量。该化合物在许多体外和体内肿瘤
细胞系统中均显示出
生物学活性。通过分别用N6-烯丙基,N6-异丙基和N6-炔丙基类似物处理,可以使荷瘤小鼠的寿命大大提高。在大鼠中,N6-烯丙基类似物使可移植乳腺肿瘤的生长速度减慢了四分之一。短链
腺苷类似物在治疗动物癌中比在白血病或肉瘤肿瘤
细胞系统中更活跃。
