Dipeptidylpeptidase9 (DPP9) is a proline-selective serine protease that plays a key role in NLRP1- and CARD8-mediated inflammatory cell death (pyroptosis). No selective inhibitors have hitherto been reported for the enzyme: all published molecules have grossly comparable affinities for DPP8 and 9 because of the highly similar architecture of these enzymes’ active sites.

Two series of nonpeptide turn mimetics were designed by analysis of the solution NMR structure of the 385-411 sequence of the gamma-chain of fibrinogen. These compounds, based on the KQAGD (Lys-Gln-Ala-Gly-Asp, 406-410) sequence, were synthesized and studied in vitro. The most interesting compound from our study, RWJ 50042 (25), exhibits potent inhibition of fibrinogen binding to GPIIb/IIIa (IC50 = 0.009 mu M), as well as thrombin- or collagen-induced platelet aggregation (IC50 = 0.76, 0.14 mu M). Since the 400-411 sequence is required for gamma-chain bioactivity and is a unique recognition sequence among ligands for integrins, vis-a-vis other RGD (Arg-Gly-Asp)-presenting proteins, these turn mimetics may represent a new, selective approach to antagonism of the fibrinogen receptor.
