Abstract
Instilling segregated cationic and lipophilic domains with an angular disposition in a trehalose-based trifaceted macrocyclic scaffold allows engineering patchy molecular nanoparticles leveraging directional interactions that emulate those controlling self-assembling processes in viral capsids. The resulting trilobular amphiphilic derivatives, featuring a Mickey Mouse architecture, can electrostatically interact with plasmid DNA (pDNA) and further engage in hydrophobic contacts to promote condensation into transfectious nanocomplexes. Notably, the topology and internal structure of the cyclooligosaccharide/pDNA co-assemblies can be molded by fine-tuning the valency and characteristics of the cationic and lipophilic patches, which strongly impacts the transfection efficacy in vitro and in vivo. Outstanding organ selectivities can then be programmed with no need of incorporating a biorecognizable motif in the formulation. The results provide a versatile strategy for the construction of fully synthetic and perfectly monodisperse nonviral gene delivery systems uniquely suited for optimization schemes by making cyclooligosaccharide patchiness the focus.

Trehalose diamide glycolipids augment antigen-specific antibody responses in a Mincle-dependent manner. Bioorg Chem 2021; 110:104747.

Abstract
Many studies have investigated how trehalose glycolipid structures can be modified to improve their Macrophage inducible C-type lectin (Mincle)-mediated adjuvanticity. However, in all instances, the ester-linkage of α,ά-trehalose to the lipid of choice remained. We investigated how changing this ester-linkage to an amide influences Mincle signalling and agonist activity and demonstrated that Mincle tolerates this functional group change. In in vivo vaccination studies in murine and ovine model systems, using OVA or Mannheimia haemolytica and Mycoplasma ovipneumoniae as vaccine antigens, respectively, it was demonstrated that a representative trehalose diamide glycolipid was able to enhance antibody-specific immune responses. Notably, IgG titres against M. ovipneumoniae were significantly greater when using trehalose dibehenamide (A-TDB) compared to trehalose dibehenate (TDB). This is particularly important as infection with M. ovipneumoniae predisposes sheep to pneumonia.

Abstract
The architectural perfection and multivalency of dendrimers have made them useful for biodelivery via peripheral functionalization and the adjustment of dendrimer generations. Modulation of the core-forming and internal matrix-forming structures offers virtually unlimited opportunities for further optimization, but only in a few cases this has been made compatible with strict diastereomeric purity over molecularly diverse series, low toxicity, and limited synthetic effort. Fully regular star polymers built on biocompatible macrocyclic platforms, such as hyperbranched cyclodextrins, offer advantages in terms of facile synthesis and flexible compositions, but core elaboration in terms of shape and function becomes problematic. Here we report the synthesis and characterization of star polymers consisting of functional trehalose-based macrocyclic cores (cyclotrehalans, CTs) and aminothiourea dendron arms, which can be efficiently synthesized from sequential click reactions of orthogonal monomers, display no cytotoxicity, and efficiently complex and deliver plasmid DNA in vitro and in vivo. When compared with some commercial cationic dendrimers or polymers, the new CT-scaffolded star polymers show better transfection efficiencies in several cell lines and structure-dependent cell selectivity patterns. Notably, the CT core could be predefined to exert Zn(II) complexing or molecular inclusion capabilities, which has been exploited to synergistically boost cell transfection by orders of magnitude and modulate the organ tropism in vivo.

Abstract
We present three easily rationalized star-shaped PEGylated β-cyclodextrin (βCD) derivatives synthesized via conjugation of different molecular weight PEG chains (5000, 2000, and 550 Da) to the βCD primary face by click chemistry (βCD-PEG5000, βCD-PEG2000, βCD-PEG550 respectively). βCDPEG systems are envisioned to further carry bioactive molecules, therefore, their interactions with biological interfaces must be determined at an early stage of development. Hence, the effect of βCDPEGs chain length on cell viability was investigated. To this aim, three models were selected: Vero cells for their fibroblast-like features; HeLa cells that are commonly used for preliminary viability screening; and human peripheral monocytes which are macrophage precursors. Of the three pegylated derivatives, βCD-PEG550 was the one that significantly affected HeLa cells and human monocytes viability. Despite the popularity of PEGylation approach, our results underscore the importance of careful and systematic PEGylated materials design for their future success in drug delivery systems.

Abstract
AIM To study the structural requirements that a cyclooligosaccharide-based nanoparticle must fulfill to be an efficient siRNA transfection vector. MATERIALS & METHODS siRNA protection from degradation by RNAses, transfection efficiency and the thermodynamic parameters of the nanoparticle/siRNA interactions were studied on pairs of amphiphilic molecules using biochemical techniques and molecular dynamics. RESULTS The lower the siRNA solvent accessible surface area in the presence of the nanoparticle, higher the protection from RNAse-mediated degradation in the corresponding nanocomplex; a moderate nanoparticle/siRNA binding energy value further facilitates reversible complexation and binding to the target cellular mRNA. CONCLUSION The use, in advance, of these parameters will provide a useful indication of the potential of a molecular nanoparticle as siRNA transfecting vector.

Abstract
Trichomoniasis is the most prevalent, non-viral sexually transmitted diseases (STD) caused by amitochondriate protozoan Trichomonas vaginalis. Increased resistance of T. vaginalis to the marketed drug Metronidazole necessitates the development of newer chemical entities. A library of sixty 2-methyl-4/5-nitroimidazole derivatives was synthesized via nucleophilic ring opening reaction of epoxide and the efficacies against drug-susceptible and -resistant Trichomonas vaginalis were evaluated. All the molecules except two were found to be active against both susceptible and resistant strains with MICs ranging 8.55-336.70 μM and 28.80-1445.08 μM, respectively. Most of the compounds were remarkably more effective than the standard Metronidazole. This study analyzes the in vitro and in vivo activities of the new 5-nitroimidazoles, which were found to be safe against human cervical HeLa cells with good selectivity index. The exploration of SAR by the synthesis of four different prototypes and 3D-QSAR study has shown the importance of prototype 1 over other prototypes.

Abstract
An increasing number of pathologies have been linked to Toll-like receptor 4 (TLR4) activation and signaling, therefore new hit and lead compounds targeting this receptor activation process are urgently needed. We report on the synthesis and biological properties of glycolipids based on glucose and trehalose scaffolds which potently inhibit TLR4 activation and signaling in vitro and in vivo. Structure-activity relationship studies on these compounds indicate that the presence of fatty ester chains in the molecule is a primary prerequisite for biological activity and point to facial amphiphilicity as a preferred architecture for TLR4 antagonism. The cationic glycolipids here presented can be considered as new lead compounds for the development of drugs targeting TLR4 activation and signaling in infectious, inflammatory, and autoimmune diseases. Interestingly, the biological activity of the best drug candidate was retained after adsorption at the surface of colloidal gold nanoparticles, broadening the options for clinical development.

Abstract
We designed multivalent β-cyclodextrin-based adsorbates bearing different anchoring groups aiming to yield stable monolayers with improved packing and close contact of the cavity to the gold surface. Toward this end the primary rim of the β-cyclodextrin was decorated with several functional groups, namely iodide, nitrile, amine, isothiocyanate, methyl sulfide, and isocyanide. Monolayers formed by these adsorbates were characterized by contact angle measurements, surface plasmon resonance spectroscopy, polarization modulation infrared reflection adsorption spectroscopy, X-ray photoelectron spectroscopy, and electrochemistry. The nature of the anchoring group influenced the adsorption kinetics, thickness, layer stability, number of anchoring groups bounded to the surface, and packing in the resulting monolayers. Therefore, chemical manipulation of multivalent adsorbates can be used to modify the properties of their monolayers.

Abstract
A systematic study of the suitability of α,α'-dibromo-o-xylene as a reagent for cyclic o-xylylene protection of vic-diols in different monosaccharide substrates is reported. The installation of this protecting group, formally equivalent to a di-O-benzylation reaction, proceeds with good regioselectivity toward 1,2-trans-diequatorial diol systems in pyranose and furanose rings. Initially, the benzyl ether-type derivative of the more acidic hydroxyl is preferentially formed. Subsequent intramolecular etherification toward the equatorial-oriented vicinal OH is kinetically favored. The methodology has been implemented for the simultaneous protection of the secondary O-2 and O-3 positions of a single d-glucopyranosyl unit in cyclic oligosaccharides of the cyclodextrin (CD) family (cyclomaltohexa-, -hepta-, and -octaose; α, β, and γCD).

Abstract
Covalent attachment of biorecognizable sugar ligands in several copies at precise positions of cyclomaltooligosaccharide (cyclodextrin, CD) macrocycles has proven to be an extremely flexible strategy to build multivalent conjugates. The commercial availability of the native CDs in three different sizes, their axial symmetry and the possibility of position- and face-selective functionalization allow a strict control of the valency and spatial orientation of the recognition motifs (glycotopes) in low, medium, high and hyperbranched glycoclusters, including glycodendrimer-CD hybrids. "Click-type" ligation chemistries, including copper(i)-catalyzed azide-alkyne cycloaddition (CuAAC), thiol-ene coupling or thiourea-forming reactions, have been implemented to warrant full homogeneity of the adducts. The incorporation of different glycotopes to investigate multivalent interactions in heterogeneous environments has also been accomplished. Not surprisingly, multivalent CD conjugates have been, and continue to be, major actors in studies directed at deciphering the structural features ruling carbohydrate recognition events. Nanometric glycoassemblies endowed with the capability of adapting the inter-saccharide distances and orientations in the presence of a receptor partner or capable of mimicking the fluidity of biological membranes have been conceived by multitopic inclusion complex formation, rotaxanation or self-assembling. Applications in the fields of sensors, site-specific drug and gene delivery or protein stabilization attest for the maturity of the field.

Abstract
Progenitor and pluripotent cell types offer promise as regenerative therapies but transfecting these sensitive cells has proven difficult. Herein, a series of linear trehalose-oligoethyleneamine "click" copolymers were synthesized and examined for their ability to deliver plasmid DNA (pDNA) to two progenitor cell types, human dermal fibroblasts (HDFn) and rat mesenchymal stem cells (RMSC). Seven polymer vehicle analogs were synthesized in which three parameters were systematically varied: the number of secondary amines (4-6) within the polymer repeat unit (Tr4(33), Tr5(30), and Tr6(32)), the end group functionalities [PEG (Tr4(128)PEG-a, Tr4(118)PEG-b), triphenyl (Tr4(107)-c), or azido (Tr4(99)-d)], and the molecular weight (degree of polymerization of about 30 or about 100) and the biological efficacy of these vehicles was compared to three controls: Lipofectamine 2000, JetPEI, and Glycofect. The trehalose polymers were all able to bind and compact pDNA polyplexes, and promote pDNA uptake and gene expression [luciferase and enhanced green fluorescent protein (EGFP)] with these primary cell types and the results varied significantly depending on the polymer structure. Interestingly, in both cell types, Tr4(33) and Tr5(30) yielded the highest luciferase gene expression. However, when comparing the number of cells transfected with a reporter plasmid encoding enhanced green fluorescent protein, Tr4(33) and Tr4(107)-c yielded the highest number of HDFn cells positive for EGFP. Interestingly, with RMSCs, all of the higher molecular weight analogs (Tr4(128)PEG-a, Tr4(118)PEG-b, Tr4(107)-c, Tr4(99)-d) yielded high percentages of cells positive for EGFP (30-40%).

Abstract
Syntheses of the novel oligodiaminosaccharides, α-(1→4)-linked-2,6-diamino-2,6-dideoxy-D-glucopyranose oligomers, and their interactions with nucleic acid duplexes DNA-DNA, RNA-RNA, and DNA-RNA are described. Monomers to tetramers of oligodiaminoglucose derivatives having α-glycosyl bonds were successfully synthesized using a chain elongation cycle including glycosylation reactions of a 6-phthalimide glycosyl donor. UV melting experiments for a variety of nucleic acid duplexes in the absence and presence of the oligodiaminosaccharides were performed. The synthesized oligodiaminosaccharides exhibited notable thermodynamic stabilization effects on A-type RNA-RNA and DNA-RNA duplexes, whereas B-type DNA-DNA duplexes were not stabilized by the synthesized oligodiaminosaccharides. Among the oligodiaminosaccharides, the tetramer exhibited the highest ability to stabilize A-type duplexes, and the increase in T(m) values induced by the tetramer were higher than those induced by neomycin B and tobramycin, which are known aminoglycosides having ability to bind and stabilize a variety of RNA molecules. CD spectrometry experiments revealed that the oligodiaminosaccharides caused small structural changes in RNA-RNA duplexes, whereas no appreciable changes were observed in the structure of DNA-DNA duplexes. ITC (isothermal titration calorimetry) experiments demonstrated that the amount of heat generated by the interaction between RNA-RNA duplexes and the tetradiaminosaccharides was approximately double that generated by that between DNA-DNA duplexes and the tetradiaminosaccharides. These results strongly suggested the existence of an A-type nucleic acid specific-binding mode of the oligodiaminosaccharides, which bind to these duplexes and cause small structural changes.

Abstract
Herein, three new glycopolymers have been synthesized via "click polymerization" to promote nucleic acid delivery in the presence of biological media containing serum. These structures were designed to contain a trehalose moiety to promote biocompatibility, water solubility, and stability against aggregation, amide-triazole groups to enhance DNA binding affinity, and an oligoamine unit to facilitate DNA encapsulation, phosphate neutralization, and interactions with cell surfaces. A 2,3,4,2',3',4'-hexa-O-acetyl-6,6'-diazido-6,6'-dideoxy-D-trehalose (4) monomer was polymerized via copper(I)-catalyzed azide-alkyne cycloaddition with a series of dialkyne-amide comonomers that contain either one, two, or three Boc-protected secondary amines (7a, 7b, or 7c, respectively). After deprotection, three water-soluble polycations (9a, 9b, or 9c) were obtained with similar degrees of polymerization (n = 56-61) to elucidate the role of amine number on nucleic acid binding, complex formation, stability, and cellular delivery. Gel electrophoresis and ethidium bromide experiments showed that 9a-9c associated with plasmid DNA (pDNA) and formed complexes (polyplexes) at N/P ratios dependent on the amine number. TEM experiments revealed that 9a-9c polyplexes were small (50-120 nm) and had morphologies (spherical and rodlike) associated with the polymer chain stiffness. Dynamic light scattering studies in the presence of media containing serum demonstrated that 9c polyplexes had a low degree of flocculation, whereas 9a and 9b polyplexesd aggregate rapidly. Further biological studies revealed that these structures were biocompatible and deliver pDNA into HeLa cells. Particularly, 9c polyplexes promoted high delivery efficacy and gene expression profiles in the presence of serum.
