    摘要:
    黑色素生成障碍导致几种病理,包括白癜风疾病。紫外线(UV)窄带光疗(308或311 nm)用于治疗白癜风。然而,光疗的机理尚不清楚。白癜风伴随着(6 R)-1-赤型5,6,7,8-四氢生物蝶呤(H 4 Bip)的新合成增加了三倍,其过量和进一步氧化可被认为是引起白癜风的重要因素。白癜风的发病机理。(H 4 Bip),作为苯丙氨酸4-羟化酶的辅酶,催化苯丙氨酸氧化为酪氨酸(黑色素前体)。在这种情况下,H 4发生光转化已经研究了在缓冲水溶液中的浸泡。HPLC-MS / MS已证明,H 4 Bip自氧化的蝶呤产品(7,8-二氢蝶呤(H 2 Ptr),二氢黄蝶呤和蝶呤)比生物蝶呤产品(7,8-二氢双蝶呤(H 2 Bip)和生物蝶呤)占优势。我们已经表明,紫外线辐射加速了自氧化,而H 4 Bip的氧化降解产物充当了光敏剂。H的光氧化的显着特点4从自氧化的Bip是dihydropterin的形成(Н 2

  • METHOD OF SYNTHESIZING TETRAHYDROBIOPTERIN
    申请人:Henderson Mark

    公开(公告)日:2009-08-06
    The present disclosure provides a method that efficiently produces (6R)-tetrahydrobiopterin in high yield and purity. The method includes the step of hydrolyzing diacetylbiopterin to biopterin under basic conditions in a biphasic mixture comprising an organic phase and an aqueous phase. After substantially complete hydrolysis of diacetylbiopterin, the aqueous phase containing biopterin can be separated from the organic phase containing most of the organic impurities, which avoids the time-consuming step of isolating biopterin as a solid. The aqueous solution containing biopterin is stereoselectively hydrogenated to (6R)-tetrahydrobiopterin under basic conditions and high hydrogen pressure in the presence of a metal catalyst (e.g., a platinum catalyst). To improve the purification of an acid addition salt of (6R)-tetrahydrobiopterin (e.g., (6R)-tetrahydrobiopterin dihydrochloride), any residual salts (e.g., sodium salts) in the aqueous solution after the hydrogenation reaction can be removed by contacting the aqueous solution with an ion (e.g., cation) exchange resin or column. Alternatively, removal of residual salts from the aqueous solution can be omitted if an organic amine (e.g., diethylamine or triethylamine) rather than an inorganic base is used in the hydrolysis and/or hydrogenation reactions.
    本公开提供了一种高效地在高产率和纯度下生产(6R)-四氢生物蝶啶的方法。该方法包括在包含有机相和水相的两相混合物中,在碱性条件下水解二乙酰生物蝶啶至生物蝶啶的步骤。在二乙酰生物蝶啶基本完全水解后,含有生物蝶啶的水相可以与含有大部分有机杂质的有机相分离,避免了将生物蝶啶分离为固体的耗时步骤。含有生物蝶啶的水溶液在碱性条件和高氢压下,在金属催化剂的存在下(例如,铂催化剂)立体选择性地氢化为(6R)-四氢生物蝶啶。为了提高对(6R)-四氢生物蝶啶的酸盐(例如,(6R)-四氢生物蝶啶二盐酸盐)的纯化,可以通过将氢化反应后水溶液中的任何残留盐(例如,钠盐)与离子(例如,阳离子)交换树脂或柱接触来去除。另外,如果在水解和/或氢化反应中使用有机胺(例如,二乙胺或三乙胺)而不是无机碱,则可以省略从水溶液中去除残留盐的步骤。
