A method of treating neoplastic disease which comprises the steps of:
(a) administering to a patient in need of such treatment an effective amount of a radiation-activated cytotoxin prodrug (RACP) which has low toxicity, which can be reduced by reducing agents generated by the radiolysis of water (the equated electron and/or the hydrogen radical) and which, upon reduction, releases a sufficient amount of an effector of sufficient cytotoxic potency to kill tumour cells; and
(b) irradiating said tumour cells to reduce the prodrug which is present at the locus of said tumour cells to release said cytotoxic effector.
In preferred embodiments, the RACP is of formula (I), (VI), (VII) or (VIII).
一种治疗肿瘤性疾病的方法,包括以下步骤
(a) 给需要这种治疗的病人服用有效量的辐射活化细胞毒素原药(RACP),该原药毒性低,可被水的辐射分解产生的还原剂(等价电子和/或氢自由基)还原,还原后释放出足够量的具有足够细胞毒性效力的效应物,以杀死肿瘤细胞;以及
(b) 对所述肿瘤细胞进行辐照,以还原存在于所述肿瘤细胞部位的原药,从而释放所述细胞毒性效应物。
在优选的实施方案中,RACP 是式 (I)、(VI)、(VII) 或 (VIII)。
