帕利伐米性质、用途与生产工艺

概述帕利伐米（IPM）是环磷酰胺（CPA）的常见代谢产物。帕利伐米被认为是CPA表现出的至少一部分抗肿瘤活性的原因。直接使用帕利伐米作为抗癌剂的努力未获成功，部分原因是该化合物的不稳定性。已经合成了帕利伐米并且已经对该化合物进行了初步的生物学评估，但遗憾的是帕利伐米太不稳定而不能被分离并用于人类治疗。
生物活性 Palifosfamide (ZIO-201, Isophosphamide mustard)是新型的DNA烷化剂，是异环磷酰胺（ifosfamide）的活性代谢产物，具有抗肿瘤活性。
体外研究

Palifosfamide lysine (ZIO-201) is a stable form of palifosfamide. Palifosfamide lysine has broad activity in sarcoma lines in vitro . The IC ₅₀ ranges from 2.25 ro 6.75 μM for most cell lines except OS222 (IC ₅₀ =31.5 μM).
体内研究

Tumor growth inhibition is seen in both OS31 and OS33 xenografts and the RMS xenograft resulting in a significant difference in event-free survival between the control and the treated groups. Differential gene expression of ALDH3A1 but not ALDH1A1 is noted in the OS31 xenograft. Stabilized palifosfamide administered to mice suppresses MX-1 tumor growth by greater than 80% with 17% complete antitumor responses. Oral bioavailability in rats is 48-73% of parenteral administration, and antitumor activity in mice is equivalent by both routes. Treatment with palifosfamide-tris combined with docetaxelor doxorubicin at optimal regimens results in complete tumor regression in 62-75% of mice.
