Talabostat mesylate

Talabostat is a nonselective inhibitor of post-proline cleaving serine proteases. 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 induces powerful anti-tumor immune responses in syngeneic cancer models.
