WP1130 - Calbiochem (C15-1307-665)

General description

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-κB activities (IC₅₀<1 M in MCL cells) leading to tumor cell apoptosis (IC₅₀ ~1.2 M in Z138 cells). Suggested to modify active site cysteine of DUB and inhibit USP5, UCH-L1, USP9x, USP14, and UCH37 activities (≥80% inhibition at 5 M) 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.
