  Synthesis and influenza virus sialidase inhibitory activity of analogues of 4-guanidino-Neu5Ac2en (GG167) with modified 5-substituents

  摘要：

  Analogues of 4-guanidino-Neu5Ac2en (GG167) have been prepared containing alternative amide and sulfonamide substituents at the 5-position. (4S,5R,6R)-4-guanidino-5-(2,2,2-trifluoroacetylamino)-6-(1R,2R,3-trihydroxypropyl)-5,6-dihydro-4H-pyran-2-carboxylic acid 5 and (4S,5R,6R)-4-guanidino-5-methanesulfonylamino-6-(1R,2R,3-trihydroxypropyl)-5,6-dihydro-4H-pyran-2-carboxylic acid 6 were the only analogues which approached the activity of GG167, showing potent inhibition of influenza virus sialidases and good antiviral activity in vitro.

  Inhibitors of human neuraminidase enzymes (NEU) are recognized as important tools for the study of the biological functions of NEU and will be potent tools for elucidating the role of these enzymes in regulating the repertoire of cellular glycans. Here we report the discovery of selective inhibitors of the human neuraminidase 1 (NEU1) and neuraminidase 2 (NEU2) enzymes with exceptional potency. A library

  人神经氨酸酶（NEU）的抑制剂被认为是研究NEU生物学功能的重要工具，将是阐明这些酶在调节细胞聚糖组成中的作用的有效工具。在这里，我们报告发现人类神经氨酸酶1（NEU1）和神经氨酸酶2（NEU2）酶具有特殊效力的选择性抑制剂的发现。修饰的2-deoxy-2,3-didehydro- N的文库合成了具有乙酰基神经氨酸（DANA）类似物的C5-或C9位置，并针对四种人类神经氨酸酶同工酶（NEU1-4）进行了评估。NEU1可以很好地容纳在C5和C9位置带有酰胺连接基的疏水基团，并且发现一个六氨基基团在两个位置均具有最佳效价。尽管C5-六氨基-C9-六氨基-DANA类似物未显示出协同修饰的协同改进，但在单个位置上延伸的烷基酰胺与第二个位置上的较小基团相结合，增强了效力。确定的最佳NEU1抑制剂是具有K i与其他同工酶相比，具有53±5 nM的选择性和340倍的选择性。此外，我们证明了C5修饰结合C

  Human parainfluenza virus type 1 is the major cause of croup in infants and young children. There is currently neither vaccine nor clinically effective treatment for parainfluenza virus infection. Hemagglutinin-neuraminidase glycoprotein is a key protein in viral infection, and its inhibition has been a target for 2-deoxy-2,3-didehydro-D-N-acetylneuraminic acid (Neu5Ac2en)-based inhibitor development. In this study, we explore the effect of C-5 modifications on the potency of Neu5Ac2en derivatives that target the human parainfluenza type-1 hemagglutinin-neuraminidase protein. Our study demonstrates that the replacement of the Neu5Ac2en C-5 acetamido moiety with more hydrophobic alkane-based moieties improves the inhibitory potency for both hemagglutinin-neuraminidase functions. These findings shed light on the importance of C-S substitution on Neu5Ac2en in the design of novel sialic acid-based inhibitors that target human parainfluenza type-1 hemagglutinin-neuraminidase.
