产品描述: | Talabostat mesylate (Val-boroPro mesylate; PT100 mesylate) is an orally active and nonselective dipeptidyl peptidase IV (DPP-IV) inhibitor (IC50 < 4 nM; Ki = 0.18 nM) and the first clinical inhibitor of fibroblast activation protein (FAP) (IC50 = 560 nM), inhibits DPP8/9 (IC50 = 4/11 nM; Ki = 1.5/0.76 nM), quiescent cell proline dipeptidase (QPP) (IC50 = 310 nM), DPP2, and some other DASH family enzymes. Antineoplastic and hematopoiesis- stimulating activities |

体内研究: |
Talabostat mesylate (Val-boroPro mesylate) can stimulate immune responses against tumors involving both the innate and adaptive branches of the immune system. In WEHI 164 fibrosarcoma and EL4 and A20/2J lymphoma models, Talabostat mesylate (Val-boroPro mesylate) causes regression and rejection of tumors. The antitumor effect appears to involve tumor-specific CTL and protective immunological memory. Talabostat mesylate (Val-boroPro mesylate) treatment of WEHI 164-inoculated mice increases mRNA expression of cytokines and chemokines known to promote T-cell priming and chemoattraction of T cells and innate effector cells |
