Talabostat (PT-100, Val-boroPro) is a potent, nonselective, orally available inhibitor of post-proline cleaving serine proteases with Ki of 0.18 nM for DPP4, also potently inhibits DPP8/9 (IC50=1.5/0.76 nM), FAP, DPP2 and some other DASH family enzymes.
Talabostat (PT-100, Val-boroPro) is a potent, nonselective, orally available inhibitor of post-proline cleaving serine proteases with Ki of 0.18 nM for DPP4, also potently inhibits DPP8/9 (IC50=1.5/0.76 nM), FAP, DPP2 and some other DASH family enzymes.
Talabostat induces powerful anti-tumor immune responses in syngeneic cancer models.
Talabostat shows the inhibition of the highly related cytosolic serine proteases Dpp8 and Dpp9 (Dpp8/9) by Val-boroPro was recently demonstrated to trigger an immunostimulatory form of programmed cell death known as pyroptosis selectively in monocytes and macrophages.
Talabostat activates the inflammasome sensor protein Nlrp1b, which in turn activates pro-caspase-1 to mediate pyroptosis.
