VLX1570
CAS No. : 1431280-51-1
MCE 国际站：VLX1570
产品活性：VLX1570是蛋白酶体脱泛素酶 (DUBs) 的竞争性抑制剂，IC50 约10 μM。
研究领域：Cell Cycle/DNA Damage
作用靶点：Deubiquitinase
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. 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. 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.
In Vivo: VLX1570 (3 mg/kg) significantly decreases tumor growth in mice bearing KMS-11 multiple myeloma cells. VLX1570 (4.4 mg/kg, i.p.) markedly suppresses tumor growth, without obvious weight loss and other signs of systemic toxicity in the Waldenstrom macroglobulinemia (WM)-bearing mice.
