  A series of tritylated and dimethoxytritylated analogues of selected pyrimidine and purine nucleosides were synthesized and evaluated for their in vitro inhibitory activity against two important members of the genus Flavivirus in the Flaviviridae family, the yellow fever (YFV) and dengue viruses (DENV). Among all compounds tested, the 5′‐O‐tritylated and the 5′‐O‐dimethoxytritylated 5‐fluorouridine

  合成了一系列选定的嘧啶和嘌呤核苷的三苯甲基化和二甲氧基三苯甲基化的类似物，并评估了它们对黄病毒科中黄病毒属的两个重要成员黄热病和登革热病毒的体外抑制活性。在所有测试的化合物中，5'-O-三苯甲基化和5'-O-二甲氧基三苯甲基化的5-氟尿苷衍生物均具有抗YFV的能力。有趣的是，在嘌呤类似物系列中，5'O，N-双三苯甲基化的氟达拉滨衍生物在μm浓度下表现出对DENV的强抑制活性，但对YFV的效力却明显减弱。

  hit 3′,5′-bistritylated uridine 1, a series of alkylated nucleoside analogues were synthesized and evaluated for their in vitro antiviral activities against dengue fever virus and yellow fever virus. Hereto, alkyl and aryl groups were attached at various positions of the sugar ring combined with subtle variation of the heterocyclic base. Among the new series of derivatives, 3′,5′-di-O-trityl-5-fluoro-2′-deoxyuridine

  几种黄病毒，例如黄热病病毒和登革热病毒，会在人体内引起严重的致命感染。继我们最初的命中3'，5'-双歧化尿苷1之后，合成了一系列烷基化核苷类似物，并评估了它们对登革热病毒和黄热病病毒的体外抗病毒活性。迄今为止，烷基和芳基连接在糖环的各个位置，并带有杂环碱基的细微变化。在新的衍生物系列中，3'，5'- di- O-三苯甲基-5-氟-2'-脱氧尿苷（39）是该系列中最有效的衍生物，可抑制黄热病病毒和登革热病毒的复制，其50有效浓度百分比（EC 50）〜1μg/ mL，无明显细胞毒性。其他氟化衍生物被证明更具毒性。几乎所有具有3'，5'-二-O-苯甲酰基-2'-脱氧尿苷（50）的二苯基甲基化嘧啶核苷都具有很强的低至1μg/ mL的细胞毒性作用。

  Tuberculosis (TB) is a major health problem worldwide. We herein report a new class of pyrimidine nucleosides as potent inhibitors of Mycobacterium tuberculosis (M. tuberculosis). Various 2'- or 3'-halogeno derivatives of pyrimidine nucleosides containing uracil, 5-fluorouracil, and thymine bases were synthesized and evaluated for antimycobacterial activities. Among the compounds tested, 3'-bromo-3'-deoxy-arabinofuranosylthymine (3') was the most effective antituberculosis agent in the in vitro assays against wild-type M. tuberculosis strain (H37Ra) (MIC50 = 1 mu g/mL) as well as drug-resistant (H37Rv) (rifampicin-resistant and isoniazid-resistant) strains of M. tuberculosis (MIC50 = 1-2 mu g/mL). Compound 3' also inhibited intracellular M. tuberculosis in a human monocytic cell line infected with H37Ra, demonstrating higher activity against intramacrophagic mycobacteria (80% reduction at 10 mu g/mL concentration) than extracellular mycobacteria (75% reduction at 10 mu g/mL concentration). In contrast, pyrimidine nucleosides possessing 5-fluorouracil base were weak inhibitors of M. tuberculosis. No cytotoxicity was found up to the highest concentration of compounds tested (CC50 > 100-200 mu g/mL) against a human cell line. Overall, these encouraging results substantiate the potential of this new class of compounds as promising antituberculosis agents.
• Synthesis and interaction with uridine phosphorylase of 5'-deoxy-4',5-difluorouridine, a new prodrug of 5-fluorouracil

  5'-Deoxy-4',5-difluorouridine (4'-F-5'-dFUrd) (10) has been synthesized on the basis of the rationale that the labilization of the glycosidic linkage caused by the 4'-fluoro substituent might allow this compound to be a better prodrug form of the anticancer drug 5-fluorouracil (FUra) than is the widely studied fluoropyrimidine 5'-deoxy-5-fluorouridine (5'-dFUrd). The rate of solvolytic hydrolysis of the glycosidic linkage of 4'-F-5'-dFUrd at pH 1 was about 500-fold faster than that of 5'-dFUrd. Since uridine phosphorylase is thought to be the enzyme that causes degradation of 5'-dFUrd in vivo to generate FUra, we compared the substrate interactions of 5'-dFUrd and 4'-F-5'-dUrd with this enzyme. The Vmax for hydrolysis of 4'-F-5'-dFUrd to FUra by uridine phosphorylase was about 5-fold greater than that of 5'-dFUrd, whereas the Km value of 4'-F-5'-dFUrd was 10-fold lower. The combination of these two factors results in 4'-F-5'-dFUrd having a 50-fold higher value of V/K than does 5'-dFUrd. Against L1210 cells in culture, the IC50 value for growth inhibition by 4'-F-5'-dFUrd was 3 X 10(-7) compared to 3 X 10(-6) for 5'-dFUrd.
