BACKGROUND/AIM: The use of cardenolides in the treatment of cardiac insufficiency is well-established. However, the potential of cardenolides in tumor therapy has not been comprehensively studied. The aim of the present study was to characterize the cytotoxic effects of the new semisynthetic cardenolide analog AMANTADIG (3β-[2-(1-amantadine)-1-on-ethylamine]-digitoxigenin), and the cardenolide digitoxin on leukemia and urological tumor cell lines.
The anti-proliferative effects of AMANTADIG and digitoxin on leukemia and urological cancer cell lines were analyzed using (3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) tetrazolium reduction viability assay.
AMANTADIG and digitoxin exhibited anti-proliferative activities against the leukemia cell lines in the low nanomolar range. The prostate cancer and renal cell carcinoma cell lines were equally sensitive to AMANTADIG and digitoxin, however, the leukemia cell lines were more sensitive to both cardenolides.
The new cardenolide analog AMANTADIG appears effective in cell growth inhibition of leukemia and urological tumor cell lines.
背景/目的:强心甾类化合物用于治疗心脏功能不全已得到充分证实。然而,强心甾类化合物在肿瘤治疗中的潜力尚未得到全面研究。本研究的目的是表征新型半合成强心甾类类似物AMANTADIG(3β-[2-(1-金刚烷)-1-氧代乙胺]-洋地黄毒苷元)和强心甾类化合物洋地黄毒苷对白血病和泌尿系统肿瘤细胞系的细胞毒性作用。
使用(3-(4,5-二甲基噻唑-2-基)-2,5-二苯基四氮唑溴盐)四氮唑还原活力测定法分析AMANTADIG和洋地黄毒苷对白血病和泌尿系统癌细胞系的抗增殖作用。
AMANTADIG和洋地黄毒苷在低纳摩尔范围内对白血病细胞系表现出抗增殖活性。前列腺癌细胞系和肾癌细胞系对AMANTADIG和洋地黄毒苷同样敏感,然而,白血病细胞系对这两种强心甾类化合物更敏感。
新型强心甾类类似物AMANTADIG似乎对白血病和泌尿系统肿瘤细胞系的细胞生长抑制有效。
