A cell-permeable tyrphostin compound that acts as a partially selective deubiquitinase (DUB) inhibitor and suppresses JAK-Stat signaling pathway. Reported to cause accumulation of polyubiquitinated p53, JAK2 and Bcr-Abl, and reduce c-Myc and MCL-1 protein levels in several tumor cells and downregulate Stat3 and NF-kB activities (IC50 < 1uM in MCL cells) leading to tumor cell apoptosis (IC50 ~1.2uM in Z138 cells). Suggested to modify active site cysteine of DUB and inhibit USP5, UCH-L1, USP9x, USP14, and UCH37 activities (80% inhibition at 5uM) without affecting 20S proteasome. Reported to exert stronger antiproliferative and antitumor properties than STAT3 Inhibitor III, WP1066 in xenograft mouse models of CML and melanoma. Formula: C19H18BrN3O Solubility: DMSO Molecular Weight: 384.3 Storage and Stability: Lyophilized powder may be stored at -20C. Stable for 12 months at -20C. Reconstitute with sterile buffer or dH2O. Aliquot to avoid repeated freezing and thawing. Store at -20C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
