    摘要:
    丙型肝炎病毒(HCV)核苷抑制剂已成为近二十年来HCV药物研究的重点,这是由于此类药物中的分子对药物耐药性和泛基因型活性谱具有很高的障碍。我们的研究集中在几种有效的基于2'-卤代尿苷的HCV聚合酶抑制剂,从而发现了新颖的2'-脱氧-2'-二卤代尿苷类似物,它们在所有基因型的复制子测定中均是有效的抑制剂。为了改善这些核苷抑制剂的体内性能而进行的进一步研究确定了氨基异丁酸乙酯(AIBEE)氨基磷酸亚磷酸酯前药18a和18c,它们在犬肝中提供了高水平的活性三磷酸酯。将AIBEE前药18c与sofosbuvir(1)进行比较,方法是在狗中口服共同给药这两种化合物(每只5 mg / kg),并在给药后4和24小时测量肝中活性三磷酸代谢物的浓度。在这项研究中,在两个活检时间点,18c提供的肝脏三磷酸浓度均比sofosbuvir(1)高6倍,这表明18c可能是临床上治疗HCV感染患者的高效药物。

  • Diastereocontrolled Electrophilic Fluorinations of 2-Deoxyribonolactone: Syntheses of All Corresponding 2-Deoxy-2-fluorolactones and 2′-Deoxy-2′-fluoro-NAD<sup>+</sup>s

    Methods to construct 2'-deoxy-2'-fluoro nucleosides have undergone limited improvement in the last 20 years in spite of the substantially increased value of these compounds as pharmaceuticals and as tools for studying biological processes. We herein describe a consolidated approach to synthesize precursors to these commercially and scientifically valuable compounds via diastereocontrolled fluorination of the readily available precursor 2-deoxy-D-ribonolactone. With employment of appropriate sterically bulky silyl protecting groups at the 3 and 5 positions, controlled electrophilic fluorination of the Li-ribonolactone enolate by N-fluorodibenzenesulfonamide yielded the corresponding 2-deoxy-2-fluoroarabinolactone in high isolated yield (72%) The protected 2-deoxy-2,2-difluororibonolactone was obtained similarly in high yield from a second round of electrophilic fluorination (two steps, 51% from protected ribonolactone starting material). Accomplishment of the difficult ribofluorination of the lactone was achieved by the directive effects of a diastereoselectively installed (x-trimethylsilyl group. Electrophilic fluorination of a protected 2-deoxy-2-trimethylsilylarabinolactone via enolate generation provided the protected 2-deoxy-2-fluororibolactone as the exclusive fluorinated product. The reaction also yielded the starting material, the desilylated protected 2-deoxyribonolactone, which was recycled to provide a 38% chemical yield of the fluorinated product (versus initial protected ribonolactone),after consecutive silylation and fluorination cycles. Using our fluorinated sugar precursors, we prepared the 2'-fluoroarabino-, 2'-fluororibo-, and 2',2'-difluoronicotinamide adenine dinucleotides (NAD(+)) of potential biological interest. These syntheses provide the most consolidated and efficient methods for production of sugar precursors of 2'-deoxy-2'-fluoronucleosides and have the advantage of utilizing an air-stable electrophilic fluorinating agent. The fluorinated NAD(+)s are anticipated to be useful for studying a variety of cellular metabolic and signaling processes.

    Application of the Keck C-allylation of organic halides to 2-bromo-2-deoxy-D-arabinonolactone resulted in the formation of mixtures of 2-C-allyl lactones. The stereochemical preferences observed were dictated by the nature of vicinal and remotely placed substituents in the lactone.
  • Synthesis of isomeric analogues of S- ribosylhomocysteine analogues with homocysteine unit attached to C2 of ribose

    molecules. In this work, the synthesis of 2-deoxy-2-bromo-SRH analogues was attempted by the coupling of the corresponding 2-bromo-2-deoxypentafuranosyl sugars with the homocysteinate anion. The displacement of the bromide from C2 rather than the expected substitution of the mesylate group from C5 was observed leading to a novel isomeric analogue of SRH in which Hcy moiety is attached to a ribose ring via
