| Hazard Information | Back Directory | [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. | [Uses]
1G244 is a potent DPP8/9 inhibitor with IC50s of 12 nM and 84 nM, respectively. 1G244 does not inhibit DPPIV and DPPII. 1G244 induces apoptosis in multiple myeloma cells and has anti-myeloma effects[1][2]. | [in vivo]
1G244 (30 mg/kg; subcutaneous injection; once-a-week; for 3 weeks; NOG female mice) treatment apparently suppresses the subcutaneous growth of MM.1 S cells in murine xenograft model[1]. | Animal Model: | NOD/Shi-scid IL-2Rγnull (NOG) female mice (6-7 weeks; 19-21?g) injected with MM.1?S cells[1] | | Dosage: | 30 mg/kg | | Administration: | Subcutaneous injection; once-a-week; for 3 weeks | | Result: | Apparently suppressed the subcutaneous growth of MM.1?S cells in murine xenograft model.
