  摘要：

  Purpose. The specific activities of the purine and pyrimidine metabolizing enzymes, purine nucleoside phosphorylase (PNP), adenosine deaminase (ADA) and cytidine deaminase (CDA) were determined in bovine brain microvessel endothelial cells (BBMECs), whole cerebral tissue and erythrocytes. In addition, the substrate specificities (K-m and V-max) of purified calf spleen PNP for inosine and 2',3'-dideoxyadenosine (ddI) and of purified calf intestinal ADA for 2',3'-dideoxyadenosine (ddA), 6-chloro-2',3'-dideoxypurine (6-Cl-ddP), and 2'-beta-fluoro-2',3'-dideoxyadenosine (F-ddA) have been explored.Methods. BBMECs were isolated from bovine cerebral cortex by a two step enzymatic dispersion treatment followed by centrifugation over 50% Percoll density gradients. Activities of alkaline phosphatase, gamma-glutamyl transpeptidase, ADA, PNP and CDA were determined in various tissue homogenates (cerebral cortex, BBMECs and erythrocytes). Enzyme kinetic studies were also conducted using commercially available enzymes and several nucleoside analogs of interest.Results. The activities of ADA and PNP were 42-fold and 247-fold higher in the cerebral microvessels than in the cerebral cortex, respectively, while there was no detectable CDA activity in the microvessel fraction and very little overall activity in the cortex.Conclusions. ADA and PNP may serve as an enzymatic blood-brain barrier for some of the anti-HIV dideoxynucleosides. Simulations of brain availability for ddI, ddA, 6-Cl-ddP, and F-ddA demonstrated that the quantitative significance of enzyme localization may vary dramatically however, depending on the membrane permeability of the drug and its bioconversion rate constant within the endothelial cell.

  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

  In order to study the structure-activity relationships of 2',3'-dideoxypurine nucleosides as potential anti-HIV agents, various 6-substituted purine analogues have been synthesized and examined in virus-infected and uninfected human peripheral blood mononuclear cells. N6-methyl-2',3'-dideoxyadenosine (D2MeA, 7a) was initially synthesized from adenosine via 2',3'-O-bisxanthate 3. As extension of this

  为了研究2'，3'-二脱氧嘌呤核苷作为潜在的抗HIV药物的构效关系，已经合成了多种6-取代的嘌呤类似物，并在病毒感染和未感染的人外周血单核细胞中进行了研究。N6-甲基-2'，3'-二脱氧腺苷（D2MeA，7a）最初是通过2'，3'-O-双黄药3由腺苷合成的。由于该反应扩展到其他N6-取代的化合物失败，因此采用了全合成方法利用2'，3'-二脱氧核糖衍生物9合成其他嘌呤核苷。通过与N6-甲基腺嘌呤23缩合，由合适的碳水化合物24合成了N6-甲基-2'，3'-二脱氧腺苷，2'-氟阿拉伯呋喃糖基类似物32（D2MeFA）的酸稳定衍生物。N6-甲基衍生物（D2MeA）7a被证明是最有效的抗病毒药物之一。对于6个取代的化合物，其效力顺序为NHMe大于NH2大于Cl约N（Me）2大于SMe大于OH约NHEt大于SH大于NHBn约H。 2'，3'-二脱氧嘌呤核苷的6位可能决定这些化合物的抗病毒活性。发现酸
