Polyamines, such as putrescine and spermine, are naturally occurring substances intimately associated with normal and neoplastic growth. High levels are found in cancer patients and are associated with tumour growth. Experiments with V79 hamster cells cultured in vitro have demonstrated that the presence of putrescine and spermine can significantly reduce the cytotoxicity of the commonly used chemotherapy agent cis-DDP. These data may have clinical implications.
多胺,如腐胺和精胺,是与正常生长和肿瘤生长密切相关的天然存在的物质。在癌症患者体内发现其水平较高,且与肿瘤生长有关。对体外培养的V79仓鼠细胞进行的实验表明,腐胺和精胺的存在可显著降低常用化疗药物顺铂的细胞毒性。这些数据可能具有临床意义。
