In Vitro
VLX1570 inhibits USP14 and UCHL5 activity of 19S regulatory particles, and the inhibition of USP14 is more pronounced. VLX1570 (1 μM) shows inhibitory activity against USP14 in KMS-11 myeloma cells. VLX1570 exhibits an IC50 of 0.58 μM on HCT116 cells[1]. VLX1570 binds to recombinant USP14 with Kd of 1.5-18?μM using two different sources of recombinant protein, and the Kd for recombinant UCHL5 is higher (14-18?μM) compared to that of USP14. VLX1570 has potent antiproliferative activities on multiple myeloma cells, with IC50s of 43?±?2 nM, 74?±?2 nM, 126?±?3 nM, and 191?±?1 nM for KMS-11, RPMI8226, OPM-2, and OPM-2-BZR cells, respectively[2]. VLX1570 suppresses the viability of BCWM.1 cells, with an EC50 of 20.22?nM. VLX1570 (100, 250, 500 nM) induces significant apoptosis by 12?h in a dose-dependent manner in all Waldenstrom macroglobulinemia (WM) cell lines tested, including BCWM.1/IR (IR) and BCWM.1/BR (BR) subclones. VLX1570 (100, 250, 500 nM) also causes ER stress machinery and mitochondrial damage in WM cells. VLX1570 (250?nM) downregulates BCR-signalosome components and their end effectors, as well as CXCR4 expression in WM cells[3].
