Abstract
Sialic acid derivatives, analogs, and their conjugates are important pharmacophores. Modification of the C-4 hydroxyl group of sialic acid can lead to derivatives, such as zanamivir, with potent anti-influenza activities. Herein, we described the synthesis of C-4-modified sialic acid derivatives via conjugation with naturally derived pentacyclic triterpenes, which are active ingredients of traditional Chinese medicine, and the evaluation of their in vitro anti-influenza virus activity in MDCK cells. Interestingly, a set of configurational isomers was obtained during the de-O-acetylation reaction of two pentacyclic triterpene-sialic acid conjugates under Zemplén conditions, and a mechanism was proposed. Owing to the attachment of the Neu5Ac2en moiety, all synthesized conjugates displayed lower hydrophobicity than their parent compounds. In comparison with ursane- and lupane-type triterpenes, oleanane-type triterpene-functionalized Neu5Ac2en conjugates were most promising. The insertion of a (1,2,3-triazol-4-yl)-methyl between the amide bond and Neu5Ac2en caused a substantial decrease in activity. Compound 15a exhibited the highest inhibitory activity (IC50 = 8.3 μM) and selectivity index (SI = 22.7). Further studies involving hemagglutination inhibition and neuraminidase inhibition suggested that compound 15a inhibited virus-induced hemagglutination with no effect on the enzymatic activity of neuraminidase, indicating that the antiviral activity appeared to be mediated via interaction with hemagglutinin at the initial stage of viral infection.

Abstract
We cloned, expressed, and characterized a novel beta-galactoside alpha2,6-sialyltransferase from Photobacterium leiognathi strain JT-SHIZ-119. The protein showed 56-96% identity to the marine bacterial alpha2,6-sialyltransferases classified into glycosyltransferase family 80. The sialyltransferase activity of the N-terminal truncated form of the recombinant enzyme was 1477 U/L of Escherichia coli culture. The truncated recombinant enzyme was purified as a single band by sodium dodecyl sulfate polyacrylamide gel electrophoresis through 3 column chromatography steps. The enzyme had distinct activity compared with known marine bacterial alpha2,6-sialyltransferases. Although alpha2,6-sialyltransferases cloned from marine bacteria, such as Photobacterium damselae strain JT0160, P. leiognathi strain JT-SHIZ-145, and Photobacterium sp. strain JT-ISH-224, show only alpha2,6-sialyltransferase activity, the recombinant enzyme cloned from P. leiognathi strain JT-SHIZ-119 showed both alpha2,6-sialyltransferase and alpha2,6-linkage-specific neuraminidase activity. Our results provide important information toward a comprehensive understanding of the bacterial sialyltransferases belonging to the group 80 glycosyltransferase family in the CAZy database.

Abstract
Highly water-soluble, artificial glycopolypeptides with a gamma-polyglutamic acid (gamma-PGA) backbone derived from Bacillus subtilis sp. and multivalent sialyloligosaccharide units have been chemoenzymatically synthesized as potential polymeric inhibitors of infection by bird and human influenza viruses. 5-Trifluoroacetamidopentyl beta-N-acetyllactosaminide and 5-trifluoroacetamidopentyl beta-lactoside were enzymatically synthesized from LacNAc and lactose, respectively, by cellulase-mediated condensation with 5-trifluoroacetamido-1-pentanol. After deacetylation, the resulting 5-aminopentyl beta-LacNAc and beta-lactoside glycosides were coupled to the alpha-carboxyl groups of the gamma-PGA side chains. The artificial glycopolypeptides carrying LacNAc and lactose were further converted to Neu5Acalpha2-(3/6)Galbeta1-4Glcbeta and Neu5Acalpha2-(3/6)Galbeta1-4GlcNAcbeta sialyloligosaccharide units by alpha2,3- and alpha2,6-sialyltransferase, respectively. The interaction of these glycopolypeptides with various influenza virus strains has been investigated by three different methods. Glycopolypeptides carrying Neu5Acalpha2,6LacNAc inhibited hemagglutination mediated by influenza A and B viruses, and their relative binding affinities for hemagglutinin were 10(2)- to 10(4)-fold higher than that of the naturally occurring fetuin control. A glycopolypeptide carrying Neu5Acalpha2,6LacNAc inhibited infection by A/Memphis/1/71 (H3N2) 93 times more strongly than fetuin, as assessed by cytopathic effects on virus-infected MDCK cells. The avian virus [A/duck/Hong kong/4/78 (H5N3)] bound strongly to Neu5Acalpha2,3LacNAc/Lac-carrying glycopolypeptides, whereas the human virus [A/Memphis/1/71 (H3N2)] bound to Neu5Acalpha2,6LacNAc in preference to Neu5Acalpha2,6Lac. Taken together, these results indicate that the binding of viruses to terminal sialic acids is markedly affected by the structure of the asialo portion, in this case either LacNAc or lactose, in the sugar chain of glycopolypeptides.

Abstract
Neomembranes composed of either bovine brain lipid that contains sialoglycolipids or egg yolk lecithin that does not, were formed on an HPA sensor chip and used to study the binding of influenza A virus in real time by surface plasmon resonance. Virus bound only to the bovine brain lipid membrane. This was confirmed by an 84% reduction in virus binding after treatment of the neomembrane with neuraminidase. Binding was temperature dependent, being highest at 30-35 degrees C and lower at 10 degrees C. Surprisingly, the rate of complex formation was enhanced, rather than inhibited, by the presence of 1.34-25.2 x 10(6) molecules of free NANA per virus binding site and the rate of dissociation was lower suggesting that the complex was more stable. The free energy of association to form the transition complex was increased by 3 kJ mol(-1) and there was an almost 10-fold increase in the enthalpy of complex formation in the presence of free NANA. These results show the value of surface plasmon resonance for measuring complex molecular interactions in real time, and provide a model that can be used to study the effectiveness of inhibitors of attachment of influenza virus to its receptor molecules.

Abstract
We synthesized polyvalent sialidase inhibitors bearing 4-guanidino-Neu5Ac2en analogues on the polyglutamic acid back bone, via a spacer of alkyl ether at the C-7 position. These multivalent conjugates 9 and 10 showed enhancement of antiviral activity against infuenza A virus and more potent efficacy in vivo relative to a monomeric sialidase inhibitor.
