  Biological Properties of N-Acyl and N-Haloacetyl Neuraminic Acids: Processing by Enzymes of Sialic Acid Metabolism, and Interaction with Influenza Virus

  摘要：

  Several unnatural N-acyl neuraminic acids (N-propionyl, N-hexanoyl, N-benzoyl, N-trifluoroacetyl, N-chloroacetyl, N-difluoroacetyl) were prepared enzymatically using immobilised sialic acid aldolase. N-Trifluoroacetyl- N-chloroacetyl- and N-difluoroacetyl neuraminic acids were shown to enhance up to 10-fold the rate of association of influenza virus A to a sialoglycolipid neomembrane by surface plasmon resonance, and were found to act as weak inhibitors (K-iapp 0.45-2.0 mM) of influenza virus neuraminidase. The N-propionyl, N-chloroacetyl- and N-difluoroacetyl neuraminic acids were found to be substrates for recombinant Escherichia coli CMP sialate synthase, to give the corresponding CMP-N-acyl-neuraminic acids. CMP-N-propionyl neuraminic acid was found not to be a substrate for CMP-N-acetyl neuraminic acid hydroxylase from pig submandibular gland. (C) 2002 Elsevier Science Ltd. All rights reserved.

  are urgently needed. Here, we report the structure-based drug design, synthesis, and evaluation in vitro and in cellular systems of sialic acid derivatives able to inhibit the bacterial sialic acid symporter SiaT. We designed and synthesized 21 sialic acid derivatives and screened their affinity for SiaT by a thermal shift assay and elucidated the inhibitory mechanism through binding thermodynamics

  抗生素耐药性是全球关注的主要问题，迫切需要具有机制新颖作用模式的新药。在这里，我们报告了能够抑制细菌唾液酸转运体 SiaT 的唾液酸衍生物在体外和细胞系统中的基于结构的药物设计、合成和评价。我们设计并合成了 21 种唾液酸衍生物，并通过热位移分析筛选了它们对 SiaT 的亲和力，并通过结合热力学、计算方法和抑制动力学研究阐明了抑制机制。与天然底物相比，最有效的化合物具有 180 倍的亲和力，在细菌生长试验中进行了测试，表明耐甲氧西林金黄色葡萄球菌的细菌生长延迟. 这项研究代表了开发唾液酸摄取抑制剂作为新型抗菌剂的第一个例子和有希望的领先优势。

  The invention relates to inhibitors of polysialic (PSA) de-N-acetylase, methods of their production and use. The methods involve use of a PSA de-N-acetylase inhibitor for modifying the growth of cells, such as inhibiting the growth of cancer cells. The compositions include an inhibitor of a PSA de-N-acetylase, such as N-substituted derivatives of the amino sugars hexosamine and neuraminic acid, as well as conjugates and aggregates. Also provided are pharmaceutical compositions that include a PSA de-N-acetylase inhibitor of the invention. Kits containing one or more inhibitor compositions of the invention, as well as methods of preparing the compositions also are provided.
