Current Research


Sialidases are enzymes which can catalyze the hydrolysis of glycosidic linkage of terminal sialic acid (N-acetylneuraminic acid) residues in oligosaccharides and other glycoconjugates. Human sialidases are four types and classified on the basis of their localization.

NEU1 - Intralysosomal sialidase, NEU2 - Cytosolic sialidase, NEU3 - Plasma membrane-associated sialidase and NEU4 - mitochondrial membrane-associated sialidase.

These isoforms differ in their substrate specificities, enzymatic properties, and physiological functions. Human sialidases plays a wide variety of biological processes namely cell metabolism, cell differentiation, cell growth, and apoptosis including immune functions.

Sialic acids have also been found to be involved in the proliferation of cancer cells, where they are usually over-expressed on the surface glycoproteins of some cancer cell lines. Gangliosides, present on the plasma membrane of cancer cells, play an important role in the regulation of these cells. Specific human sialidase (NEU3) on gangliosides induces inhibition of apoptosis and promotes cancer cell mobility (metastasis) in some colon and rectal cancer cells.

We are currently interested in developing selective non carbohydrate inhibitors of human sialidase (NEU3).
