  • Clinical applications of tetrahydrobiopterin, lipoic acid and their salts and methods of preparing tetrahydrobiopterin bis-lipoate

    Dosage forms and methods of use are disclosed for: a) the simultaneous administration of tetrahydrobiopterin (BH4) or a derivative, homolog or precursor thereof and lipoic acid (LA), or dihydrolipoic acid (DHLA), or a derivative, homolog or salt thereof or, b) the administration of a conjugate consisting of tetrahydrobiopterin bis-lipoate (TBL). The invention is useful for the amelioration of diabetes mellitus types 1 and 2 (including impaired glucose tolerance, pre-diabetes, insulin resistance, metabolic syndrome X and as an adjunct to oral antidiabetic agents and/or insulin), diabetic and non-diabetic microvascular diseases (including nephropathy, neuropathy and retinopathy), diabetic and non-diabetic macrovascular diseases (including heart attack, stroke, peripheral vascular disease and ischemia-reperfusion injury), hypertension, vasoconstriction, obesity, dyslipedemia, and neurodegenerative disorders (including Parkinson's disease, mild cognitive impairment, senile dementia, Alzheimer's disease, hearing loss and chronic glaucomas). A novel method for the preparation of TBL is also disclosed.

    vitiligo. (H4Bip), as the phenylalanine 4-hydroxylase coenzyme, catalyzes the oxidation of phenylalanine to tyrosine (a melanin precursor). In this context, photo-transformation of H4Bip in aqueous buffer solutions has been studied. HPLC–MS/MS has demonstrated that pterin products of H4Bip autoxidation (7,8-dihydropterin (H2Ptr), dihydroxanthopterin and pterin) predominate over biopterin products (7

  • The Synthesis of 6-Aminomethyl-5,6,7,8-Tetrahydropterin
    作者:P Waring
    DOI:10.1071/ch9880667
    日期:——

    6-Aminomethyl-5,6,7,8-tetrahydropterin has been prepared by reduction of 2-acetamido-6-cyanopteridin-4(3H)-one* to 2-acetamido-6-aminomethyl- 5,6,7,8-tetrahydropteridin-4(3H)-one followed by acid hydrolysis. The hitherto undescribed 6-cyanopterin was prepared by careful hydrolysis of the 2-acetamido compound prepared by dehydration of the oxime derived from 2-acetamido-6-formylpteridin-4(3H)-one. The latter was prepared by selenium dioxide oxidation of the methyl compound. Oxidation of 6-aminomethyl-5,6,7,8-tetrahydropterin at neutral pH appears to proceed with significant side-chain loss in Tris buffer but not in phosphate buffer.

    通过将 2-乙酰氨基-6-氰基蝶啶-4(3H)-酮*还原为 2-乙酰氨基-6-氨基甲基-5,6,7,8-四氢蝶啶-4(3H)-酮,然后进行酸水解,制备出了 6-氨基甲基-5,6,7,8-四氢蝶啶。通过对 2-乙酰氨基-6-甲酰基蝶啶-4(3H)-酮肟脱水制备的 2-乙酰氨基化合物进行仔细水解,制备出了迄今为止尚未发现的 6-氰基蝶呤。后者是通过二氧化硒氧化甲基化合物制备的。在中性 pH 值下,6-氨甲基-5,6,7,8-四氢蝶呤的氧化似乎是在三羟甲基丙烷缓冲液中进行的,但在磷酸盐缓冲液中侧链损失不大。

    an efficient HPLC-MS/MS method to achieve the separation of qH2Bip from H4Bip and other oxidation products in less than 3.5 min. The application of this method to the investigation of H4Bip autoxidation kinetics clearly shows that qH2Bip's half-life is much longer than previously reported, and mostly longer than that of H4Bip, irrespective of the considered experimental conditions. These findings definitely
    在人类中,四氢生物蝶呤 (H4Bip) 是几种重要羟基化反应的辅助因子,其功能障碍会在任何年龄段导致非常严重的疾病。因此,生物介质中蝶呤的测定对于 H4Bip 缺陷的诊断和监测至关重要。在发现 H4Bip 的生理作用以及最近出现与 H4Bip 缺乏相关的多巴胺和血清素紊乱的基因治疗半个多世纪后,醌类二氢生物蝶呤 (qH2Bip)(H4Bip 的瞬时中间体)的定量尚未被考虑然而。这主要是由于其半衰期较短,根据之前的研究,半衰期为 0.9 至 5 分钟。基于我们最近披露的 qH2Bip 的特定 MS/MS 转变,我们开发了一种高效的 HPLC-MS/MS 方法,可在 3.5 分钟内实现 qH2Bip 与 H4Bip 和其他氧化产物的分离。该方法在 H4Bip 自氧化动力学研究中的应用清楚地表明,无论考虑的实验条件如何,qH2Bip 的半衰期比以前报道的要长得多,并且大多比 H4Bip 长。这些发现明确证实
