LDN192960 (LDN 192960) is a highly potent and selective DYRK2 inhibitor with IC50 of 13 nM toward DYRK2 at 50 uM ATP.LDN192960 suppresses Thr25 RPT3 phosphorylation in a dose-dependent manner in HEK293T cells transiently overexpressing DYRK2-FLAG, with maximal effects at 1-10 uM.LDN192960 does not inhibit any of the 130+ kinases including other CMGC kinase family members that are closely related to the DYRKs.LDN192960 binds to the ATP-binding pocket of DYRK2, also potently inhibits DYRK1A, DYRK3 and Pim with IC50 of <3, 122 and 10 nM, respectively.LDN192960 perturbs proteasome activity, induces cell death, and impedes proliferation and invasion on MDA-MB-468 cells.LDN192960 impedes MM progression and delays myeloma-mediated bone degeneration.LDN192960 induces cytotoxicity in bortezomib-resistant MM, both in cells and in vivo. significantly alleviates tumor burden in standard and PDX TNBC models.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
