The concept of targeted drug delivery evolved from the “magic bullet” idea put forth by Paul Ehrlich more than a century ago, whose original intention was to kill disease-causing microbes without harming the body itself. In this minireview, we highlight sugar-mediated targeted delivery strategies that capitalize on the unique metabolic features of cancer cells (the so-called Warburg effect) and bacteria to enhance the efficacy of anti-cancer chemotherapeutics and antimicrobials, respectively. The differences in metabolism between cancerous and normal cells, and how the overexpression of sugar transporters in cancer cells can be capitalized for cancer therapy are first discussed. Subsequently, different designs of sugar-conjugated therapeutic agents and delivery systems are presented. Finally, we show that while targeting bacterial cells metabolism to increase antimicrobial efficacy is based on a different concept from that employed for cancer therapy, co-administration of antimicrobials with glucose and other metabolites either in the free form or conjugated to carriers can increase bacterial cells susceptibility to antimicrobial agents.

Summary Background To our knowledge, no previous study has prospectively documented the incidence of common diseases and related mortality in high-income countries (HICs), middle-income countries (MICs), and low-income countries (LICs) with standardised approaches. Such information is key to developing global and context-specific health strategies. In our analysis of the Prospective Urban Rural Epidemiology (PURE) study, we aimed to evaluate differences in the incidence of common diseases, relat...

Carbohydrate–lectin interactions are involved in a number of relevant biological events including fertilization, immune response, cell adhesion, tumour cell metastasis, and pathogen infection. Lectins are also tissue specific, making carbohydrates not only promising drug candidates but also excellent low molecular weight ligands for active drug delivery system decorations. In order for these interactions to be effective multivalency is essential, as the interaction of a lectin with its cognate m...

Metabolic glycoengineering of unnatural monosaccharides provides a facile method to label cancer cells with chemical tags for glycan imaging and cancer targeting. Multiple types of monosaccharides have been utilized for metabolic cell labeling. However, the comparison of different types of monosaccharides in labeling efficiency and selectivity has not been reported. In this study, we compared N-azidoacetylgalactosamine (GalAz) and N-azidoacetylmannosamine (ManAz) for metabolic labeling of HepG2 ...

Abstract Five BODIPY derivatives containing different number of styryl units were designed and synthesized based on the Knoevenagel reactions. All compounds were characterized by NMR and HRMS. The single crystal structures of compounds 1 and 3–5 were confirmed by X-ray crystallography. The photophysical and electrochemical properties of these dyes were also investigated by UV/Vis spectroscopy, fluorescence spectroscopy, and cyclic voltammetry. Our study indicates that the optical and electronic ...

Abstract Globally, one in six deaths is reported due to cancer suggesting the critical need for development of advanced treatment regimens. In this study, solid lipid nanoparticles (SLN) were prepared and appended with polyethylene glycol (PEGylated) galactose and a multikinase inhibitor sorafenib (SRFB) was used as chemotherapeutic drug, for treating hepatocellular carcinoma (HCC). The nanoparticles were evaluated for in-vitro and in-vivo performances to showcase the targeting efficiency and th...

Purpose In order to overcome the obstacles and side effects of classical chemotherapy, numerous studies have been performed to develop the treatment based on targeted transport of active compounds directly to the site of action. Since tumor cells are featured with intensified glucose metabolism, we set out to develop innovative, glucose-modified PAMAM dendrimer for the delivery of doxorubicin to breast cancer cells.

Bacterial biofilms cause chronic infections due to their inherent tolerance to antimicrobial therapies. We describe and compare the efficacy of two types of sugar (D-glucose and D-mannose)-modified cyclodextrin nanocarriers (CD-GLU and CD-MAN) loaded with antibacterial agents for preventing and eradicating bacterial biofilm. The antibacterial agents comprise a quorum sensing inhibitor (5,6-dimethyl-2-aminobenzimidazole, DMABI) and two antibiotics (erythromycin and rifampicin), and the cyclodextr...

A series of glycosides and glycoconjugates of diterpenoid isosteviol (16-oxo-ent-beyeran-19-oic acid) with various monosaccharide residues were synthesized and their cytotoxicity against some human cancer and normal cell lines was assayed. Most of the synthesized compounds demonstrated moderate to significant cytotoxicity against human cancer cell lines M-HeLa and MCF-7. Three lead compounds exhibited selective cytotoxic activities against M-HeLa (IC50 = 10.0–15.1 μM) that were three times bette...

Triple-negative breast cancer (TNBC) is a devastating disease worldwide, for which targeted imaging and therapeutic agents remain elusive. There has been growing awareness that carbohydrates are valuable as drug candidates and targeting agents for a variety of human diseases, including cancers that overexpress carbohydrate receptors on the cell surface. Here, we develop a two-dimensional (2D) glycocluster by means of simple, stepwise self-assembly for the targeted delivery of theranostic agents ...

Abstract In this work, a new pH-responsive nanocarrier based on mesoporous silica nanoparticle which was functionalized by polyamidoamine dendrimer with sugar conjugation was designed for targetable and controllable delivery of deferasirox to cancer cells. To obtain the optimum conditions for the preparation of drug-loaded nanocarrier, the response surface method was employed. The effect of drug/silica ratio, temperature, and operation time on loading efficiency of deferasirox was evaluated, and...

Nanoparticles (NPs) are novel platforms that can carry both cancer-targeting molecules and drugs to avoid severe side effects due to nonspecific drug delivery in standard chemotherapy treatments. Cancer cells are characterized by abnormal membranes, metabolic changes, the presence of lectin receptors, glucose transporters (GLUT) overexpression, and glycosylation of immune receptors of programmed death on cell surfaces. These characteristics have led to the development of several strategies for c...

Matrix metalloproteinases (MMPs) and A disintegrin and Metalloproteinase (ADAMs) are zinc-dependent endopeptidases belonging to the metzincin superfamily. Upregulation of metzincin activity is a major feature in many serious pathologies such as cancer, inflammations, and infections. In the last decades, many classes of small molecules have been developed directed to inhibit these enzymes. The principal shortcomings that have hindered clinical development of metzincin inhibitors are low selectivi...
