By cleaving N-terminal Xaa-Pro or Xaa-Ala residues, Talabostat mesylate (Val-boroPro mesylate) inhibits dipeptidyl peptidases, such as FAP, resulting in the stimulation of cytokine and chemokine production and specific T-cell immunity and T-cell dependent activity[3].
Talabostat mesylate (Val-boroPro mesylate) competitively inhibits the dipeptidyl peptidase (DPP) activity of FAP and CD26/DPP-IV, and there is a high-affinity interaction with the catalytic site[4].

Activation of CARD8 inflammasome by HIV-1 in THP-1 cells. CARD8-KO THP-1 cells expressing wild-type or mutant CARD8 were exposed to HIV reporter virus NL4-3-ΔEnv-EGFP pseudotyped with the VSVG envelope for six hours before LDH. Talabostat mesylate (VbP, 5 μM) was used as a positive control, as it induces cell death and IL-1β secretion.

Mice: BLM (0.5mg/kg/day) is administered on days -7, -6, -5, -2, -1, 0 in the nostrils of male mice. Talabostat (40 µg/mouse) or vehicle (0.9% NaCl) is dosed per os twice daily from day 1-14. MRI is performed before BLM and at days 0, 7 and 14. After the last MRI acquisition, animals are euthanised and the lungs harvested for histological and quantitative real-time polymerase chain reaction (qRT-PCR) analyses[4].
