Background:

WP1130, also known as degrasyn, is a second-generation tyrphostin derivative initially identified as a Janus-activated kinase (JAK)-signal transducer and activator of transcription (STAT) pathway inhibitor that reduces STAT activation stimulated by cytokines (such as IL-6 and IL-3) through the rapid down-regulation of upstream JAK kinases. WP1130 has also been identified as a selective deubiquitinating enzyme (DUB) inhibitor that directly inhibits DUB activity of USP9x, USP5, USP14 and UCH37 leading to rapid accumulation of polyubiquitinated proteins into juxtanuclear aggresomes and tumor cell apoptosis. WP1130-induced apoptosis and anti-proliferation in tumor cells have been implicated in the treatment of chronic myelogenous leukemia (CML), melanoma, glioblastoma and myeloproliferative disorders.
