Abstract
The synthesis of D-glycero-D-manno-heptose-1β,7-bisphosphate (HBP) from D-mannose is described. This synthetic approach is notable for the elongation of the seventh carbon, employing mannurono-2,6-lactone, the substrate-controlled establishment of the C-6 configuration, and the nucleophilic introduction of phosphate at the C-1 position through the utilization of 4,6-O-benzylidene-α-triflate.

Abstract
Keto sugar nucleotides (KSNs) are common and versatile precursors to various deoxy sugar nucleotides, which are substrates for the corresponding glycosyltransferases involved in the biosynthesis of glycoproteins, glycolipids, and natural products. However, there has been no KSN synthesized chemically due to the inherent instability. Herein, the first chemical synthesis of the archetypal KSN TDP-4-keto-6-deoxy-d-glucose (1) is achieved by an efficient and optimized route, providing feasible access to other KSNs and analogues, thereby opening a new avenue for new applications.

Abstract
Alternative antibacterial therapies refractory to existing mechanisms of antibiotic resistance are urgently needed. One such attractive therapy is to inhibit bacterial adhesion and colonization. Ser O-heptosylation (Ser O-Hep) on autotransporters of Gram-negative bacteria is a novel glycosylation and has been proven to be essential for bacterial colonization. Herein, we chemically synthesized glycopeptides containing this atypical glycan structure and an absolute C6 configuration through the assembly of Ser O-Hep building blocks. Using glycopeptides as haptens, we generated first-in-class poly- and monoclonal antibodies, termed Anti-SerHep1a and Anti-SerHep1b, that stereoselectively recognize Ser O-heptosylation (d/l-glycero) with high specificity in vitro and in vivo. Importantly, these antibodies effectively blocked diffusely adhering Escherichia coli 2787 adhesion to HeLa cells and in mice in a dose- and Ser O-Hep-dependent manner. Together, these antibodies represent not only useful tools for the discovery of unknown serine O-heptosylated proteins bearing various C6 chiral centers but also a novel class of antiadhesion therapeutic agents for the treatment of bacterial infection.

Abstract
Heptose phosphates—unique linkers between endotoxic lipid A and O-antigen in the bacterial membrane—are pathogen-associated molecular patterns recognized by the receptors of the innate immune system. Understanding the mechanisms of immune system activation is important for the development of therapeutic agents to combat infectious diseases and overcome antibiotic resistance. However, in practice, it is difficult to obtain a substantial amount of heptose phosphates for biological studies due to the narrow scope of the reported synthetic procedures. We have optimized and developed an inexpensive and convenient synthesis for the first performed gram-scale production of 1-O-methyl d-glycero-α-d-gluco-heptoside 7-phosphate from readily available d-glucose. Scaling up to such amounts of the product, we have increased the efficiency of the synthesis and reduced the number of steps of the classical route through the direct phosphorylation of the O6,O7-unprotected heptose. The refined method could be of practical value for further biological screening of heptose phosphate derivatives.

Abstract
Phosphorylated saccharides are valuable targets in glycochemistry and glycobiology, which play an important role in various physiological and pathological processes. The current research on phosphorylated saccharides primarily focuses on small molecule inhibitors, glycoconjugate vaccines and novel anti-tumour targeted drug carrier materials. It can maximise the pharmacological effects and reduce the toxicity risk caused by nonspecific off-target reactions of drug molecules. However, the number and types of natural phosphorylated saccharides are limited, and the complexity and heterogeneity of their structures after extraction and separation seriously restrict their applications in pharmaceutical development. The increasing demands for the research on these molecules have extensively promoted the development of carbohydrate synthesis. Numerous innovative synthetic methodologies have been reported regarding the continuous expansion of the potential building blocks, catalysts, and phosphorylation reagents. This review summarizes the latest methods for enzymatic and chemical synthesis of phosphorylated saccharides, emphasizing their breakthroughs in yield, reactivity, regioselectivity, and application scope. Additionally, the anti-bacterial, anti-tumour, immunoregulatory and other biological activities of some phosphorylated saccharides and their applications were also reviewed. Their structure-activity relationship and mechanism of action were discussed and the key phosphorylation characteristics, sites and extents responsible for observed biological activities were emphasised. This paper will provide a reference for the application of phosphorylated saccharide in the research of carbohydrate-based drugs in the future.

Abstract
Synthesis of bacterial cell surface l-glycero-d-manno-heptose (l,d-Hep)- and d-glycero-d-manno-heptose (d,d-Hep)-containing higher carbon sugars is a challenging task. Here, we report a convenient and efficient approach for the synthesis of the l,d-Hep and d,d-Hep building blocks. Using l-lyxose and d-ribose as starting materials, this approach features diastereoselective Mukaiyama-type aldol reactions as the key steps. On the basis of the synthetic l,d-Hep and d,d-Hep building blocks, we achieved the first stereoselective synthesis of the unique α-l,d-Hep-(1→3)-α-d,d-Hep-(1→5)-α-Kdo core trisaccharide of the lipopolysaccharide of Vibrio parahemolyticus O2.

Abstract
Bacterial lipopolysaccharides (LPS) are important bio-medical structures, playing a major role in the interaction with human immune systems. Their core regions, containing multiple units of l-glycero-d-manno heptoses (l,d-heptose), are highly conserved structurally (with O3 and O7 glycosidic bonds), making them an epitope of high interest for the potential development of new antibiotics and vaccines. Research in this field has always been restricted by the limited availability of the parent l,d-heptose as well as its biochemical epimeric precursor d-glycero-d-manno heptose (d,d-heptose). This problem of availability has recently been solved by us, through a rapid and efficient practical synthesis of l,d-manno-heptose peracetate demonstrated at scale. Herein we report an optimized, technically simple and versatile synthetic strategy for the differentiation of both the l-glycero and d-glycero-d-manno heptose scaffolds. Our approach is based on an orthoester methodology for the differentiation of all three positions of the sugar core using a O6, O7-tetraisopropyl disiloxyl (TIPDS) protecting group for the exocyclic positions. Furthermore, the regioselective opening toward 7-OH acceptors (6O-FTIPDS ethers) differentiates the exocyclic diol which has been demonstrated with a broader set of substrates and for both manno-heptoses for the first time.

Abstract
Natural products are useful sources in the search for biochemical probes and drug leads because of their unique biological activities. However, synthetic studies or functional analyses of polycyclic complex natural products or conjugated lipids (e.g., glycolipids) are often hampered because of their synthesis and handling are challenging. On the basis of rational designs, synthetic studies, and chemical modifications, natural products need to be optimized to more potent compounds with improved activities, selectivities and/or physical properties. We have been synthesizing natural products and their derivatives for the elucidation of their biological mechanisms and discovery of drug leads. This review describes three topics for developing functional compounds derived from natural products for prospective involvement in pharmaceutical research: 1) direct construction of the ergot alkaloid scaffold by palladium catalyzed domino cyclization of amino allenes; 2) identification of novel sphingosine kinase inhibitors through a structure-activity relationship study of jaspine B; and 3) design, synthesis and biological evaluation of novel CD1d glycolipid ligands containing modified lipid moieties.

Abstract
The chemoenzymatic synthesis of a series of C6-modified GDP-d-Man sugar nucleotides is described. This provides the first structure-function tools for the GDP-d-ManA producing GDP-d-mannose dehydrogenase (GMD) from Pseudomonas aeruginosa. Using a common C6 aldehyde functionalization strategy, chemical synthesis introduces deuterium enrichment, alongside one-carbon homologation at C6 for a series of mannose 1-phosphates. These materials are shown to be substrates for the GDP-mannose pyrophosphorylase from Salmonella enterica, delivering the required toolbox of modified GDP-d-Mans. C6-CH3 modified sugar-nucleotides are capable of reversibly preventing GDP-ManA production by GMD. The ketone product from oxidation of a C6-CH3 modified analogue is identified by high-resolution mass spectrometry.

Abstract
During an infection, the detection of pathogens is mediated through the interactions between pathogen-associated molecular patterns (PAMPs) and pathogen recognition receptors. β-Heptose 1,7-bisphosphate (βHBP), an intermediate of the lipopolysaccharide (LPS) biosynthesis pathway, was recently identified as a bacterial PAMP. It was reported that βHBP sensing leads to oligomerization of TIFA proteins, a mechanism controlling NF-κB activation and pro-inflammatory gene expression. Here, we compare the ability of chemically synthesized βHBP and Shigella flexneri lysate to induce TIFA oligomerization in epithelial cells. We find that, unlike bacterial lysate, βHBP fails to initiate rapid TIFA oligomerization. It only induces delayed signaling, suggesting that βHBP must be processed intracellularly to trigger inflammation. Gene deletion and complementation analysis of the LPS biosynthesis pathway revealed that ADP-heptose is the bacterial metabolite responsible for rapid TIFA oligomerization. ADP-heptose sensing occurs down to 10-10 M. During S. flexneri infection, it results in cytokine production, a process dependent on the kinase ALPK1. Altogether, our results rule out a major role of βHBP in S. flexneri infection and identify ADP-heptose as a new bacterial PAMP.

Abstract
d-Glycero-β-d-manno-heptose 1,7-biphosphate (β-HBP) is a novel microbial-associated molecular pattern that triggers inflammation and thus has the potential to act as an immune modulator in many therapeutic contexts. To better understand the structure-activity relationship of this molecule, we chemically synthesized analogs of β-HBP and tested their ability to induce canonical TIFA-dependent inflammation in human embryonic kidney cells (HEK 293T) and colonic epithelial cells (HCT 116). Of the analogs tested, only d-glycero-β-d-manno-heptose 1-phosphate (β-HMP) induced TIFA-dependent NF-κB activation and cytokine production in a manner similar to β-HBP. This finding expands the spectrum of metabolites from the Gram-negative ADP-heptose biosynthesis pathway that can function as innate immune agonists and provides a more readily available agonist of the TIFA-dependent inflammatory pathway that can be easily produced by synthetic methods.

Abstract
The Mitsunobu reaction basically consists in the conversion of an alcohol into an ester under inversion of configuration, employing a carboxylic acid and a pair of two auxiliary reagents, mostly triphenylphosphine and a dialkyl azodicarboxylate. This reaction has been frequently used in carbohydrate chemistry for the modification of sugar hydroxy groups. Modification at the anomeric position, leading mainly to anomeric esters or glycosides, is of particular importance in the glycosciences. Therefore, this review focuses on the use of the Mitsunobu reaction for modifications of sugar hemiacetals. Strikingly, unprotected sugars can often be converted regioselectively at the anomeric center, whereas in other cases, the other hydroxy groups in reducing sugars have to be protected to achieve good results in the Mitsunobu procedure. We have reviewed on the one hand the literature on anomeric esterification, including glycosyl phosphates, and on the other hand glycoside synthesis, including S- and N-glycosides. The mechanistic details of the Mitsunobu reaction are discussed as well as this is important to explain and predict the stereoselectivity of anomeric modifications under Mitsunobu conditions. Though the Mitsunobu reaction is often not the first choice for the anomeric modification of carbohydrates, this review shows the high value of the reaction in many different circumstances.

Abstract
The incorporation of C-glycosides in drug design has become a routine practice for medicinal chemists. These naturally occurring building blocks exhibit attractive pharmaceutical profiles, and have become an important target of synthetic efforts in recent decades. Described herein is a practical, scalable, and versatile route for the synthesis of non-anomeric and unexploited C-acyl glycosides through a Ni/photoredox dual catalytic system. By utilizing an organic photocatalyst, a range of glycosyl-based radicals are generated and efficiently coupled with highly functionalized carboxylic acids at room temperature. Distinctive features of this transformation include its mild conditions, impressive compatibility with a wide array of functional groups, and most significantly, preservation of the anomeric carbon: a handle for further, late-stage derivatization.

Abstract
d-glycero-β-d-manno-heptose 1,7-biphosphate (HBP) is an enzymatic intermediate in the biosynthesis of the heptose component of lipopolysaccharide (LPS), and was recently revealed to be a pathogen-associated molecular pattern (PAMP) that allows detection of Gram-negative bacteria by the mammalian immune system. Cellular detection of HBP depends upon its stimulation of a cascade that leads to the phosphorylation and assembly of the TRAF-interacting with forkhead-associated domain protein A (TIFA), which activates the transcription factor NF-κB. In this note, an alternate chemical synthesis of HBP is described and its biological activity is established, providing pure material for further assessing and exploiting the biological activity of this compound.
