Description

1G244 (847928-32-9) is a potent and selective inhibitor of the prolyl dipeptidases DPP8 (IC50 = 14 nM) and DPP9 (IC50 = 53 nM).1,2? It does not inhibit DPP2, DPP4 or fibroblast activation protein (FAP) at 100 μM.1,2 1G244 is a slow binding competitive inhibitor of DPP8 but a competitive and reversible inhibitor of DPP9.2? Inhibition of DPP8/9 by 1G244 has been shown to cause pro-caspase-1-dependent pyroptosis in macrophages and monocytes.3 1G244 also induced cell death in DPP8/9 knockout cells at higher concentration indicating there may be some off-target effects.3 1G244 blocks adipogenesis in preadipocyte 3T3-L1 and 3T3-F422A cells.4? DPP8/9 inhibition attenuates PPARg2 induction during preadipocyte differentiation.4 Because of its inhibitory effects on pro-inflammatory macrophages, 1G244 inhibition of DPP8/9 has been examined as a potential therapy for reducing atherosclerosis and/or in the prevention of plaque rupture.5,6 Cell permeable.
