目的:多胺是细胞正常生长所必需的生物阳离子。多胺类似物已被证明是有效的肿瘤生长抑制剂。我们检测了多胺类似物1,19-二(乙氨基)-5,10,15-三氮杂十一烷(BE-4-4-4-4)、N1,N11-二(乙基)降精胺(BE-3-3-3)和1,15-二(乙氨基)-4,12-二氮杂十五烷(BE-3-7-3)对前列腺癌DU145、LNCaP和PC-3细胞生长的影响。我们还通过裸鼠移植模型检测了␣BE-4-4-4-4对␣体内雄激素非依赖性DU-145细胞的影响。方法:在␣体外,用DNA法和集落形成法检测细胞增殖。结果:BE-4-4-4-4-4对前列腺癌DU145、LNCaP和PC-3细胞株的增殖抑制作用呈剂量依赖关系。经BE-4-4-4-4作用24 h后,3种细胞株细胞内腐胺、精胺和精胺水平均下降。BE-4-4-4-4对肿瘤生长的抑制作用持续到实验的第101天,抑瘤率分别为74%(3 mg/kg)和81%(5 mg/kg)。BE-4-4-4-4组动物除体重减轻外,未见明显毒性反应。与对照组相比,用BE-4-4-4-4处理的动物的肿瘤组织显示出剂量依赖性的亚精胺和精胺水平的下降,但腐胺水平没有下降。肿瘤组织中BE-4-4-4-4的水平在第63天最高,3 mg/kg和5 mg/kg剂量组的BE-4-4-4水平分别为0.33nmo1/mg蛋白和1.45nmo1/mg蛋白质。结论:多胺类似物BE-4-4-4-4、BE-3-3-3和BE-3-7-3是体外抑制前列腺癌细胞生长的有效药物,BE-4-4-4-4是体内抑制DU145细胞生长的有效药物。
Purpose: Polyamines are biologic cations necessary for normal cell growth. Polyamine analogues have been shown to be effective inhibitors of tumor growth. We tested the effect of the polyamine analogues 1,19-bis(ethylamino)-5,10,15-triazanonadecane (BE-4-4-4-4), N1,N11-bis(ethyl)norspermine (BE-3-3-3) and 1,15-bis(ethylamino)-4,12-diazapentadecane (BE-3-7-3) on the growth of the prostate cancer cell lines DU145, LNCaP and PC-3 in vitro. We also tested the effect of␣BE-4-4-4-4 on androgen-independent DU145 cells in␣vivo via a nude mouse xenograft model.Methods: In␣vitro, cell proliferation was measured using a DNA assay or a colony-formation assay. In vivo, mice were given saline or BE-4-4-4-4 3 mg/kg or 5 mg/kg intraperitoneally twice daily on days 7–10 and 14–17 (cycle 1), days 49–52 and 56–59 (cycle 2) and days 91–94 and 98–101 (cycle 3).Results: The proliferation of DU145, LNCaP and PC-3 prostate cancer cell lines was inhibited in a dose-dependent manner by BE-4-4-4-4. Intracellular putrescine, spermidine and spermine levels in all three cell lines declined after only 24 h exposure to BE-4-4-4-4 in vitro. Animals receiving BE-4-4-4-4 showed inhibition of tumor growth which continued throughout the experiment with 74% (3 mg/kg) and 81% (5 mg/kg) growth inhibition seen on day 101. No overt toxic reactions besides weight loss were observed in BE-4-4-4-4-treated animals. Tumor tissue from animals treated with BE-4-4-4-4 showed a dose-dependent decrease in spermidine and spermine levels but no decline in putrescine levels as compared with control. BE-4-4-4-4 levels were highest in tumors on day 63 with levels reaching 0.33 and 1.45 nmol/mg protein from animals treated at the 3 mg/kg and 5 mg/kg doses, respectively. Conclusion: These results show the polyamine analogues BE-4-4-4-4, BE-3-3-3 and BE-3-7-3 to be effective inhibitors of prostate cancer cell growth in vitro and BE-4-4-4-4 to be an effective inhibitor of DU145 cells in vivo with minimal toxicity.
