  Synthesis, Biotransformation, and Pharmacokinetic Studies of 9-(β-d-Arabinofuranosyl)-6-azidopurine:  A Prodrug for Ara-A Designed To Utilize the Azide Reduction Pathway

  摘要：

  As a part of our efforts to design prodrugs for antiviral nucleosides, 9-(beta-4-arabinofuranosyl)-6-azidopurine (6-AAP) was synthesized as a prodrug for ara-A that utilizes the azide reduction biotransformation pathway. 6-AAP was synthesized from ara-A via its 6-chloro analogue 4. The bioconversion of the prodrug was investigated in vitro and in vivo, and the pharmacokinetic parameters were determined. For in vitro studies, 6-AAP was incubated in mouse serum and liver and brain homogenates. The half-lives of 6-AAP in serum and liver and brain homogenates were 3.73, 4.90, and 7.29 h, respectively. 6-AAP was metabolized primarily in the liver homogenate microsomal fraction by the reduction of the azido moiety to the amine, yielding ara-A. However, 6-AAP was found to be stable to adenosine deaminase in a separate in vitro study. The in vivo metabolism and disposition of ara-A and 6-AAP were conducted in mice. When 6-AAP was administered by either oral or intravenous route, the half-life of ara-A was 7-14 times higher than for ara-A administered intravenously. Ara-A could not be found in the brain after the intravenous administration of ara-A. However, after 6-AAP administration (by either oral or intravenous route), significant levels of ara-A were found in the brain. The results of this study demonstrate that 6-AAP is converted to ara-A, potentially increasing the half-life and the brain delivery of ara-A. Further studies to utilize the azide reduction approach on other clinically useful agents containing an amino group are in progress in our laboratories.

  使用来自布鲁氏锥虫的高度通用的嘌呤核苷2'-脱氧核糖基转移酶酶促合成治疗性核苷

  摘要：

  与多步化学方法相比，使用酶来合成核苷类似物具有多个优势，包括化学，区域和立体选择性以及较温和的反应条件。本文报道了来自布鲁氏锥虫的嘌呤核苷2'-脱氧核糖基转移酶（PDT）的生产，表征和利用。Tb PDT是一种二聚体，不仅在很宽的温度范围（50–70°C），pH（4–7）和离子强度（0–500 mM NaCl）范围内都显示出出色的活性和稳定性，而且在高温下具有非凡的高稳定性碱性条件（pH 8-10）。bPDT被证明可以熟练地合成许多治疗性核苷，包括去羟肌苷，维达拉滨，克拉屈滨，氟达拉滨和奈拉拉滨。用Ala或Ser进行结构指导的Val11置换，导致变体的活性提高了2.8倍。Tb PDT也共价固定在戊二醛激活的磁性微球上。选择了M Tb PDT3作为最佳衍生物（4200 IU / g，活性回收率为22％），可以轻松地将其重新捕获和再循环用于> 25个反应，而活性损失可忽略不计。最后，男铽PDT3
