Abstract

alpha-Difluoromethylornithine (DFMO) and methylglyoxal-bis-guanylhydrazone (MGBG), when administered simultaneously, inhibited growth and were highly toxic to the Dunning R 3327-G hormone-resistant prostatic adenocarcinoma transplanted into Copenhagen rats. Neither DFMO (2%) nor MGBG at a nontoxic dose (15 mg/kg) inhibited tumor growth, but total (47% early cure rate) or near total suppression of growth of established tumors was observed in rats receiving both treatments.

摘要

α-二氟甲基鸟氨酸(DFMO)和甲基乙二醛双脒腙(MGBG)同时给药时,可抑制移植到哥本哈根大鼠体内的邓宁R 3327-G激素抵抗性前列腺腺癌的生长,且具有高毒性。单独使用DFMO(2%)或无毒剂量的MGBG(15毫克/千克)均不能抑制肿瘤生长,但在接受两种治疗的大鼠中,观察到已形成肿瘤的生长被完全(早期治愈率47%)或几乎完全抑制。
