    3-dioxane (5) provided 2-amino-6-chloro-9-[2,(2,2-dimethyl-1,3-dioxan-5-yl)ethyl]purine (6) in high yield. This aminochloropurine 6 was readily converted to the antiviral acyclonucleoside 9-[4-hydroxy-3-(hydroxymethyl)but-1-yl]guanine (1) and to its 6-chloro (10), 6-thio (11), 6-alkoxy (12-17), 6-amino (20), and 6-deoxy (21) purine analogues. The guanine derivative 1 was converted to its xanthine analogue
    2-氨基-6-氯嘌呤与5-(2-溴乙基)-2,2-二甲基-1,3-二恶烷(5)烷基化可提供2-氨基-6-氯-9- [2,(2,2 -二甲基-1,3-二氧杂环己烷-5-基)乙基]嘌呤(6)的高产率。该氨基氯嘌呤6易于转化为抗病毒无环核苷9- [4-羟基-3-(羟甲基)丁-1-基]鸟嘌呤(1)及其6-氯(10),6-硫代(11),6 -烷氧基(12-17),6-氨基(20)和6-脱氧(21)嘌呤类似物。鸟嘌呤衍生物1转化为其黄嘌呤类似物9。类似地,用5进行6-氯嘌呤的烷基化提供了通往1的次黄嘌呤类似物8的途径。在这9个取代的嘌呤中,鸟嘌呤衍生物1显示出对疱疹的最高活性。细胞培养物中的1型和2型单纯性病毒,在某些测试中,它比阿昔洛韦更具活性,没有证据表明对细胞有毒性。

    Recombinant human aldehyde oxidase (AO) was expressed in Escherichia coli. Different cell disruption methods and conditions of cell culture in shake flasks and bioreactors and of biotransformation on an analytical scale were tested to optimize the synthesis of oxidized AO drug metabolites. The volumetric productivity was increased 24‐fold by optimizing the cell culture conditions. The highest yield

    Compositions, methods and systems for treating disordered epithelial tissues, such as is caused by pathogens and/or by toxins produced thereby. The invention relates to the use of an anti-infective and/or antimicrobial active agent in a carrier, with vigorous agitation of the disordered epithelial tissue for topical treatment thereof under such conditions sufficient to achieve clinically discernable improvement of the disordered epithelial tissue. The preferred anti-infective and/or antimicrobial active agent comprises a nucleoside, such as acyclovir, valcyclovir, penciclovir, famciclovir, ganciclovir, cidofovir, adefovir, and tenofovir, and derivatives, analogs, or metabolites thereof, or a mixture thereof, or 1-docosanol, optionally in combination with an organohalide. The inventive compositions and methods may employ the use of an applicator adapted for use in promoting the penetration of the treatment composition and/or the vigorous agitation of the disordered tissue.

  • Practical syntheses of penciclovir and famciclovir from N2-acetyl-7-benzylguanine
    作者:Takayoshi Torii、Hiroshi Shiragami、Keizo Yamashita、Yumiko Suzuki、Toyoto Hijiya、Tatsuki Kashiwagi、Kunisuke Izawa
    DOI:10.1016/j.tet.2006.03.080
    日期:2006.6
    We have established practical methods for the synthesis of penciclovir (PCV) and famciclovir (FCV) from readily available guanosine via N2-acetyl-7-benzylguanine. The alkylation of N2-acetyl-7-benzylguanine proceeded selectively at the N9 position to give the desired alkylated product in good yield in salt form. After conventional catalytic hydrogenolysis of the benzyl group and hydrolysis of the resulting acetate, pure PCV was obtained without the need for chromatography. As a side chain precursor, the mesylate was selected rather than a halide since the corresponding halides gave several impurities under the same reaction conditions. Two procedures for the synthesis of FCV from PCV and a derivative are also reported. (c) 2006 Elsevier Ltd. All rights reserved.
