Description: |
Talabostat mesilate(PT-100; Val-boroPro) is an orally active, specific inhibitor of dipeptidyl peptidases(IC50=1 nM for DPP4), including tumor-associated fibroblast activation protein.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. |
