NCIt definition : A carbohydrate-based galectin inhibitor, with potential antineoplastic activity. Belapectin
binds to the carbohydrate-binding domain of galectins, especially galectin-3, and
may result in an induction of apoptosis mediated through activation of both mitochondria
and caspases. This may reduce tumor growth in galectin-overexpressing tumor cells.
Galectins, often overexpressed on tumor cells, play a key role in cancer cell proliferation,
apoptosis, tumor angiogenesis and evasion of immune responses.;
