Eur J Med Chem 2023; 259:115578. [PMID: 37467617 DOI: 10.1016/j.ejmech.2023.115578] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2023] [Revised: 06/13/2023] [Accepted: 06/15/2023] [Indexed: 07/21/2023]
Abstract
A synthetic multivalent hemagglutinin and neuraminidase inhibitor was developed by the conjugation of a septa-valent triazolylsialoside to bovine serum albumin using di-(N-succinimidyl) adipate. Matrixassisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF-MS) confirmed the attachment of five septa-valent sialyl lactosides to the protein backbone, resulting in a pentatrideca-valent sialyl conjugate. This pseudo-glycoprotein demonstrated a high affinity for hemagglutinin/neuraminidase as well as for the drug-resistant NA mutation on the influenza virus surface due to the cluster effect. The conjugate also exhibited potent antiviral activity against a wide range of virus strains without cytotoxicity at high concentrations. Mechanistic studies revealed that the pentatrideca-valent sialyl conjugate bound strongly to the influenza virion particles through interactions with HA/NA on the virion surfaces. The KD of the interaction was approximately 1 μM, as determined by isothermal calorimetric titration, allowing the capture and trapping of the influenza virions and preventing their further infection of host cells. These findings provide insight into the development of new antiviral agents using multivalent sialic acid clusters.

Abstract
Bacterial pathogens such as Nontypeable Haemophilus influenzae (NTHi) can evade the immune system by taking up and presenting host-derived sialic acids. Herein, we report a detailed structure-activity relationship of sialic acid-based inhibitors that prevent the transfer of host sialic acids to NTHi. We report the synthesis and biological evaluation of C-5, C-8, and C-9 derivatives of the parent compound 3-fluorosialic acid (SiaNFAc). Small modifications are tolerated at the C-5 and C-9 positions, while the C-8 position does not allow for modification. These structure-activity relationships define the chemical space available to develop selective bacterial sialylation inhibitors.

Abstract
We report the preparation of multivalent amide-sialoside-decorated human serum albumin (HSA) and bovine serum albumin (BSA) as mimics of natural mucin and bioshields against influenza virus infection. Free sialic acid with an amine on C-2 was covalently attached to the protein scaffolds using di-(N-succinimidyl) adipate. Dynamic light scattering (DLS) showed that the synthetic neomucins were able to act as bioshields and aggregate the influenza virion particles. The dissociation constants (KD) of the interactions between the prepared glycoconjugates and three different viral strains were measured by isothermal titration calorimetry (ITC) indicating the multivalent presentation of sialyl ligands on the HSA and BSA backbones can dramatically enhance the adsorbent capability compared to the corresponding monomeric sialoside. Hemagglutinin inhibition (HAI) and neuraminidase inhibition (NAI) assays showed that the glycoconjugates acted as moderate HA and NA inhibitors, thus impeding viral infection. Moreover, the different binding affinities of the glycoproteins to HA and NA proteins from different influenza viruses demonstrated the importance of HA/NA balance in viral replication and evolution. These findings provide a foundation for the development of antiviral drugs and viral adsorbent materials based on mimicking the structure of mucin.

Abstract
An efficient streamlined chemoenzymatic approach has been developed for gram-scale synthesis of Lewis a angtigen (LeaβProN3) and a library of sialyl Lewis a antigens (sLeaβProN3) containing different sialic acid forms. Intially, commercially available inexpensive N-acetylglucosamine (GlcNAc) was converted to its N'-glycosyl p-toluenesulfonohydrazide in one step. Followed by chemical glycosylation, GlcNAcβProN3 was synthesized using this protecting group-free method in high yield (82%). Sequential one-pot multienzyme (OPME) β1-3-galactosylation of GlcNAcβProN3 followed by OPME α1-4-fucosylation reactions produced target LeaβProN3 in gram-scale. Structurally diverse sialic acid forms was successfully introduced using a OPME sialylation reation containing a CMP-sialic acid synthetase and Pasteurella multocida α2-3-sialyltransferase 1 (PmST1) mutant PmST1 M144D with or without a sialic acid aldolase to form sLeaβProN3 containing naturally occurring or non-natural sialic acid forms in preparative scales.

Abstract
Orexin neurons regulate critical brain activities for controlling sleep, eating, emotions, and metabolism, and impaired orexin neuron function results in several neurologic disorders. Therefore, restoring normal orexin function and understanding the mechanisms of loss or impairment of orexin neurons represent important goals. As a step toward that end, we generated human orexin neurons from induced pluripotent stem cells (hiPSCs) by treatment with N-acetyl-d-mannosamine (ManNAc) and its derivatives. The generation of orexin neurons was associated with DNA hypomethylation, histone H3/H4 hyperacetylation, and hypo-O-GlcNAcylation on the HCRT gene locus, and, thereby, the treatment of inhibitors of SIRT1 and OGT were effective at inducing orexin neurons from hiPSCs. The prolonged exposure of orexin neurons to high glucose in culture caused irreversible silencing of the HCRT gene, which was characterized by H3/H4 hypoacetylation and hyper-O-GlcNAcylation. The DNA hypomethylation status, once established in orexin neurogenesis, was maintained in the HCRT-silenced orexin neurons, indicating that histone modifications, but not DNA methylation, were responsible for the HCRT silencing. Thus, the epigenetic status of the HCRT gene is unique to the hyperglycemia-induced silencing. Intriguingly, treatment of ManNAc and its derivatives reactivated HCRT gene expression, while inhibitors SIRT1 and the OGT did not. The present study revealed that the HCRT gene was silenced by the hyperglycemia condition, and ManNAc and its derivatives were useful for restoring the orexin neurons.

Abstract
We report the synthesis of multivalent oleanolic acid (OA) protein conjugates as nonglycosylated neomucin mimic for the capture and entry inhibition of influenza viruses. Oleanolic acid derivatives bearing an amine-terminated linker were synthesized by esterification of carboxylic acid and further grafted onto the human serum albumin (HSA) via diethyl squarate method. The binding of hemagglutinin (HA) on the virion surface to the synthetic neomucin was evaluated by hemagglutination inhibition assay. The influenza virus capture ability of the PEGylated OA-HSA conjugate was further investigated by Dynamic Light Scattering (DLS), virus capture assay and Isothermal Titration Calorimeter (ITC) techniques. The pronounced agglutination of viral particles, the high capture efficiency and affinity constant indicate that this neoprotein is comparable to natural glycosylated mucin, suggesting that this material could potentially be used as anti-infective barriers to prevent virus from invading host cells. The study also rationalizes the feasibility of antiviral drug development based on OA or other antiviral small molecules conjugated protein strategies.

Abstract
Secondary active transporters from the SLC17 protein family are required for excitatory and purinergic synaptic transmission, sialic acid metabolism, and renal function, and several members are associated with inherited neurological or metabolic diseases. However, molecular tools to investigate their function or correct their genetic defects are limited or absent. Using structure-activity, homology modeling, molecular docking, and mutagenesis studies, we have located the substrate-binding site of sialin (SLC17A5), a lysosomal sialic acid exporter also recently implicated in exocytotic release of aspartate. Human sialin is defective in two inherited sialic acid storage diseases and is responsible for metabolic incorporation of the dietary nonhuman sialic acid N-glycolylneuraminic acid. We built cytosol-open and lumen-open three-dimensional models of sialin based on weak, but significant, sequence similarity with the glycerol-3-phosphate and fucose permeases from Escherichia coli, respectively. Molecular docking of 31 synthetic sialic acid analogues to both models was consistent with inhibition studies. Narrowing the sialic acid-binding site in the cytosol-open state by two phenylalanine to tyrosine mutations abrogated recognition of the most active analogue without impairing neuraminic acid transport. Moreover, a pilot virtual high-throughput screening of the cytosol-open model could identify a pseudopeptide competitive inhibitor showing >100-fold higher affinity than the natural substrate. This validated model of human sialin and sialin-guided models of other SLC17 transporters should pave the way for the identification of inhibitors, glycoengineering tools, pharmacological chaperones, and fluorescent false neurotransmitters targeted to these proteins.

Abstract
N-Glycolylneuraminic acid (Neu5Gc) is a non-human sialic acid, which may play a significant role in human pathologies, such as cancer and vascular disease. Further studies into the role of Neu5Gc in human disease are hindered by limited sources of this carbohydrate. Using a chemo-enzymatic approach, Neu5Gc was accessed in six steps from glucose. The synthesis allows access to gram-scale quantities quickly and economically and produces Neu5Gc in superior quality to commercial sources. Finally, we demonstrate that the synthesized Neu5Gc can be incorporated into the cell glycocalyx of human cells, which do not naturally synthesize this sugar. The synthesis produces Neu5Gc suitable for in vitro or in vivo use.

Abstract
To elucidate the molecular mechanisms of transmission of influenza viruses between different host species, such as human and birds, binding properties of sialic acid-containing carbohydrates that are recognized by human and/or avian influenza viruses were characterized by the surface plasmon resonance (SPR) method. Differences in the binding of influenza viruses to three gangliosides were monitored in real-time and correlated with receptor specificity between avian and human viruses. SPR analysis with ganglioside-containing lipid bilayers demonstrated the recognition profile of influenza viruses to not only sialic acid linkages, but also core carbohydrate structures on the basis of equilibrated rate constants. Kinetic analysis showed different binding preferences to gangliosides between avian and human strains. An avian strain bound to Neu5Acalpha2-3nLc4Cer with much slower dissociation rate than its sialyl-linkage analog, Neu5Acalpha2-6nLc4Cer, on the lipid bilayer. In contrast, a human strain bound equally to both gangliosides. An avian strain, but not a human strain, also interacted with GM3 carrying a shorter carbohydrate chain. Our findings demonstrated the remarkable distinction in the binding kinetics of sialic acid-containing carbohydrates between avian and human influenza viruses on the lipid bilayer.

Abstract
Glucosamine is commonly used as a nutraceutical by arthritis patients. However, its mode of action is still unknown, and there is controversy about its clinical efficacy. Synthetic N-acyl glucosamines (acyl group>2 carbons) comprise a new class of drugs. We examined these derivatives for their effect in bone and cartilage cells, and for their ability to serve as acceptor substrates for galactosyltransferase. With the exception of N-benzoylglucosamine, compounds of the series were good substrates for galactosyltransferases from bone and cartilage cells, and for purified enzyme from bovine milk. When N-butyrylglucosamine (GlcNBu) was added to the cell medium of primary bovine chondrocytes and human osteoblasts, small amounts were found to enter the cells and a radiolabeled metabolite appeared in the medium. However, GlcNBu did not appear to be incorporated directly into oligosaccharides. GlcNBu at 1 and 5mM concentrations in the glucose-free cell medium of primary human osteoblasts from osteoarthritis patients did not significantly alter cell proliferation or cell differentiation.

Abstract
The glycosphingolipid globoside (globotetraosylceramide, Gb4Cer) has been proposed to be the cellular receptor of human parvovirus B19. Quantitative measurements of the binding of parvovirus B19 to Gb4Cer were performed to explore the molecular basis of the virus tropism. Solid-phase assays with fluorescence-labeled liposomes or 125iodine-labeled empty capsids were used to characterize the specificity of binding. In addition, surface plasmon resonance on lipid layers, as well as isothermal titration microcalorimetry, was utilized for real-time analysis of the virus-receptor interaction. These studies did not confirm binding of Gb4Cer to recombinant B19 VP2 capsids, suggesting that Gb4Cer does not function on its own as the cellular receptor of human parvovirus B19, but might be involved in a more complex recognition event. The biochemical results were further confirmed by cryo-electron microscopy image reconstructions at 10 A resolution, in which the structures of empty capsids were compared with empty capsids incubated with Gb4Cer.

Abstract
We have compiled 819 articles published in the year 2002 that involved commercial optical biosensor technology. The literature demonstrates that the technology's application continues to increase as biosensors are contributing to diverse scientific fields and are used to examine interactions ranging in size from small molecules to whole cells. Also, the variety of available commercial biosensor platforms is increasing and the expertise of users is improving. In this review, we use the literature to focus on the basic types of biosensor experiments, including kinetics, equilibrium analysis, solution competition, active concentration determination and screening. In addition, using examples of particularly well-performed analyses, we illustrate the high information content available in the primary response data and emphasize the impact of including figures in publications to support the results of biosensor analyses.

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.
