talabostat mesylate

Talabostat mesylate (PT100) is an orally active, selective inhibitor of dipeptidyl peptidases IV (DPP4, IC50: 0.18 nM), including tumor-associated fibroblast activation protein. 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.

Talabostat isomer mesylate, an isomer of talabostat mesylate, is a potent, nonselective, and orally available inhibitor of dipeptidyl peptidase IV (DPP-IV) with a Ki of 0.18 nM. Talabostat (PT100, Val-boroPro) is notable for its efficacy in inhibiting DPP-IV.
