    靶向蝶啶还原酶 1 的抗寄生虫吡咯并嘧啶的基于结构的设计与合成
    摘要:
    非洲人类锥虫病的治疗仍然是撒哈拉以南非洲地区未满足的主要健康需求。涉及新分子目标的方法很重要;蝶啶还原酶 1 (PTR1) 是一种在锥虫属中减少二氢生物蝶呤的酶,已被确定为候选靶标,之前已表明取代的吡咯并 [2,3- d ] 嘧啶是布氏锥虫PTR1 的抑制剂( J. Med. Chem. 2010 , 53 , 221–229)。在本研究中,61 个新的吡咯并 [2,3- d]嘧啶已经制备,设计了 23 种与 PTR1 复合的化合物的新晶体结构,并在屏幕上评估了对 PTR1 的酶抑制活性和体外抗锥虫活性。八种化合物在两个筛选中都具有足够的活性,可以进行体内评估。因此,尽管获得了小鼠 I 期疾病模型中锥虫杀灭活性的证据,但这些化合物对小鼠的毒性太大,无法进一步开发。

  • Nitrile Reductase from Geobacillus kaustophilus: A Potential Catalyst for a New Nitrile Biotransformation Reaction
    作者:Birgit Wilding、Margit Winkler、Barbara Petschacher、Regina Kratzer、Anton Glieder、Norbert Klempier
    DOI:10.1002/adsc.201200109
    日期:2012.8.13
    The cloning, expression and characterization of a nitrile reductase (NRed) from the thermophile Geobacillus kaustophilus is reported. The enzyme shows a 12-fold increase in activity in response to a temperature change from 25 °C to 65 °C. The substrate scope regarding its biocatalytic applicability was investigated by testing a range of common nitriles. The narrow substrate range observed for the wild-type
    据报道嗜热嗜热芽孢杆菌Geobacillus kaustophilus腈还原酶(NRed)的克隆,表达和鉴定。响应温度从25°C到65°C的变化,该酶的活性增加了12倍。通过测试一系列常见的腈,研究了有关其生物催化适用性的底物范围。在野生型酶中观察到的较窄的底物范围促使基于先前公开的来自枯草芽孢杆菌的同源性模型的Gk NRed活性位点突变体的合理设计。就天然底物7-氰基-7-脱氮鸟嘌呤(preQ 0)以及一系列合成的preQ 0样底物结构。观察到野生型酶活性对天然底物的特定结构修饰的明显依赖性。可以将源自preQ 0的两个非天然腈还原为相应的氨基化合物。
  • Ionic Liquid as an Efficient and Recyclable Reaction Medium for the Synthesis of Pyrido[2,3-<i>d</i>]pyrimidines

    DOI:10.1002/jhet.1515
    日期:2013.5
    Ionic liquid [bmim]BF4 was found to be an efficient and recyclable reaction medium for the one‐pot synthesis of pyrido[2,3‐d]pyrimidines. The structures of the products were characterized by IR, 1H NMR, and HRMS spectra. This method had the advantages of easier work‐up, milder reaction conditions, high yields, and environmentally benign procedure.

  • Discovery of 5-Substituted Pyrrolo[2,3-<i>d</i>]pyrimidine Antifolates as Dual-Acting Inhibitors of Glycinamide Ribonucleotide Formyltransferase and 5-Aminoimidazole-4-carboxamide Ribonucleotide Formyltransferase in De Novo Purine Nucleotide Biosynthesis: Implications of Inhibiting 5-Aminoimidazole-4-carboxamide Ribonucleotide Formyltransferase to AMPK Activation and Antitumor Activity
    作者:Shermaine Mitchell-Ryan、Yiqiang Wang、Sudhir Raghavan、Manasa Punaha Ravindra、Eric Hales、Steven Orr、Christina Cherian、Zhanjun Hou、Larry H. Matherly、Aleem Gangjee

    日期:2013.12.27
    We synthesized 5-substituted pyrrolo[2,3-d]pyrimidine antifolates (compounds 5-10) with one-to-six bridge carbons and a benozyl ring in the side chain as antitumor agents. Compound 8 with a 4-carbon bridge was the most active analogue and potently inhibited proliferation of folate receptor (FR) alpha-expressing Chinese hamster ovary and KB human tumor cells. Growth inhibition was reversed completely or in part by excess folic acid, indicating that FR alpha is involved in cellular uptake, and resulted in S-phase accumulation and apoptosis. Antiproliferative effects of compound 8 toward KB cells were protected by excess adenosine but not thymidine, establishing de novo purine nucleotide biosynthesis as the targeted pathway. However, 5-aminoimidazole-4-carboxamide (AICA) protection was incomplete, suggesting inhibition of both AICA ribonucleotide formyltransferase (AICARFTase) and glycinamide ribonucleotide formyltransferase (GARFTase). Inhibition of GARFTase and AICARFTase by compound 8 was confirmed by cellular metabolic assays and resulted in ATP pool depletion. To our knowledge, this is the first example of an antifolate that acts as a dual inhibitor of GARFTase and AICARFTase as its principal mechanism of action.
  • Structure-Based Design and Synthesis of Antiparasitic Pyrrolopyrimidines Targeting Pteridine Reductase 1

    The treatment of Human African trypanosomiasis remains a major unmet health need in sub-Saharan Africa. Approaches involving new molecular targets are important; pteridine reductase 1 (PTR1), an enzyme that reduces dihydrobiopterin in Trypanosoma spp., has been identified as a candidate target, and it has been shown previously that substituted pyrrolo[2,3-d]pyrimidines are inhibitors of PTR1 from Trypanosoma
