制备方法与用途

生物活性

Pentostatin 是有效的腺苷脱氨酶抑制剂,在治疗多种恶性淋巴增生,尤其是毛细胞白血病中非常有效。它还能与某些抗肿瘤药物发挥协同作用,并具有免疫抑制活性。

化学性质

从甲醇-水混合溶液结晶得到白色晶体,熔点为204~209.5℃或220~225℃(>150℃时会变黑)。在pH 7的水中,最大紫外吸收波长为282nm(ε值约为8000);在pH 11的水中,最大吸收波长为283nm(ε值约为7970);在pH 2的水中,初始吸收波长为273nm(开始时ε值约为7570,在6.5小时后变为3143)。[α]D^23+ 值分别为+76.4°(水溶液中C=1)和+73.0°(pH 7的缓冲液中C=1)。水中pKa值为5.2。

用途

Pentostatin 是腺苷脱氨酶(ADA)抑制剂,主要用于α-干扰素治疗无效的毛细胞白血病。

生产方法

大规模生产可通过喷妥司汀产生菌 Streptomyces cetrivioticus 的浸入或深层培养来制备:

  1. 发酵

    • 选择合适的培养基植入无菌水溶性营养液,在20~45℃(最佳为33~40℃)条件下进行充气和搅拌培育,直至培养液中出现喷妥司汀。
    • 发酵时间受设备类型、大小、搅拌速度及充气速率等因素影响。大规模工业发酵通常需3~7天可得最大收率;短时间发酵则收率较低。
  2. 分离与提纯

    • 分离:采用压滤或离心分离,滤饼用水彻底洗涤后合并洗液和滤液,并调pH值至约9.2。减压浓缩并冷却析出沉淀,用硅藻土作助滤剂过滤除去。
    • 滤液用水稀释并调pH值至约8.3,然后吸附于活性炭或Darco G-60柱子上进行纯化。分批或连续操作均可。
    • 丙酮水溶液用于洗脱,浓缩后通过活性炭柱进一步纯化,得到喷妥司汀的固体产物。

以上方法确保了Pentostatin 的高效生产和高纯度。

    To provide, in place of injected agents (nucleoside-based anticancer agents or antivirus agents) clinically used as therapeutic drugs for cancer or virus infections, a medicine that has high stability with respect to various hydrolytic metabolic enzymes, is absorbed into the body even by oral administration, and exhibits a cytocidal effect by being incorporated into a DNA and RNA biosynthetic route and inhibiting the modification and extension of DNA and RNA or inhibiting reverse transcriptases or inhibiting protein synthesis. The aforementioned problem is solved by a novel compound represented by formula (I). (In the formula, D is the 5′-position moiety of a nucleoside-based anticancer agent or an antivirus agent, and R 1 and R 2 are each a benzyl group that may have the same substituent or different substituents.)
