Abstract
Glycosidases have important anti-cancer, anti-viral and anti-diabetic properties. This review covers the literature in the past 15 years since our initial review in this journal on “neutral” glycosidase inhibitors lacking a basic nitrogen found in iminosugars and azasugars or inhibitors that are neutral by virtue of being “charge-balanced” (zwitterionic). These structurally diverse inhibitors include lactones, lactams, epoxides such as cyclophellitol, and sulfonium ion derivatives of the natural product salacinol. Synthetic efforts toward cyclophillitol, salicinol and derivatives are also highlighted. Importantly, certain metals can inhibit glycosidases and care must be taken to remove residual catalysts from synthetic material to be tested against these enzymes.
Keywords: Cadmium, computational, copper, cyclophellitol, deoxynojirimycin, diabetes, electrophilic, epoxide, fucosidase, galactosidase, glucocerebroside, glucosidase, glycal, homology, hydantocidin, iminosugar, lactam, lactone, mannosidase, metal complex, modeling, molybdenum, natural product, palladium, salacinol, sialidase, silver, transition-state mimic, vanadium, X-ray crystallography, zinc.

Drugs and Mitochondria
Mitochondria play a central role in the life and death of cells. They are not merely the center for energy metabolism but are also the headquarters for different catabolic and anabolic processes, calcium fluxes, and various signaling pathways. Mitochondria maintain homeostasis in the cell by interacting with reactive oxygen-nitrogen species ...read more
Mitochondria as a Therapeutic Target in Metabolic Disorders
Mitochondria are the primary site of adenosine triphosphate (ATP) production in mammalian cells. Moreover, these organelles are an important source of reactive oxygen and nitrogen species in virtually any nucleated cell type. The modulation of a myriad of cellular signaling pathways depends on the mitochondrial physiology. Mitochondrial dysfunction is observed ...read more
