NCIt definition : The mesylate salt of an orally active small molecule with antineoplastic and hematopoiesis-
stimulating activities. By cleaving N-terminal Xaa-Pro or Xaa-Ala residues, talabostat
inhibits dipeptidyl peptidases, such as fibroblast activation protein (FAP), resulting
in the stimulation of cytokine and chemokine production and specific T-cell immunity
and T-cell dependent activity. This agent may also stimulate the production of colony
stimulating factors, such as granulocyte colony stimulating factor (G-CSF), resulting
in the stimulation of hematopoiesis. Dipeptidyl peptidases are involved in the activation
of polypeptide hormones and chemokines.;
Alternative definition : NCI-GLOSS: A substance being studied in the treatment of cancer, including certain
types of lung, pancreas, and brain cancer. Talabostat mesylate may help the immune
system block the growth of cancer cells. It may also increase the growth of new blood
cells. It is a type of enzyme inhibitor.;
