Mechanism of Action

Features	WP1130 has an advantage in that its activity is not inhibited by a variety of Abl kinase mutations, including T315I.
Targets/IC₅₀/Ki	DUB (Cell-free assay) Bcr-Abl (Cell-free assay) 1.8 μM
In vitro	In addition to inducing rapid down-regulation of Bcr/Abl without affecting Bcr or c-Abl, Degrasyn (WP1130) also regulates the stability of Jak2 and c-Myc without affecting other kinases (HER1, HER2, c-Kit, FAK, ERK1, ERK2, Akt, Btk, Src and Src-related kinases) or transcription factors (wild-type p53, STAT1, STAT3, STAT5, c-Jun, NF-κB, and Max). Unlike adaphostin, this compound induces down-regulation of Bcr/Abl within 60 minutes. It is more effective in inducing apoptosis of myeloid and lymphoid tumor cells with IC50 of ~0.5-2.5 μM compared with normal CD34⁺ hematopoietic precursors, dermal fibroblasts, or endothelial cells with IC50 of ~5-10 μM. This chemical (5 μM) specifically and rapidly down-regulates both wild-type and T315I mutant Bcr/Abl protein without affecting bcr/abl gene expression or engaging the proteasomal degradation pathway in chronic myelogenous leukemia (CML) cells, accompanied by induction of apoptosis. It is more effective in reducing leukemic cell colony formation compared with normal progenitor cells, and effective against primary leukemic cells harboring the T315I mutation. This compound induces rapid proteasomal-dependent degradation of c-Myc protein in MM-1 multiple myeloma and other tumor cell lines, correlated with tumor growth inhibition. Unlike AG490, it acts as a partly selective deubiquitinase (DUB) inhibitor to induce a rapid and marked accumulation of polyubiquitinated (K48/K63-linked) proteins into juxtanuclear aggresomes without affecting proteasome activity. This chemical (5 μM) directly inhibits DUB activity of USP9x, USP5, USP14, UCH-L1, and UCH37, but not UCH-L3, resulting in downregulation of antiapoptotic and upregulation of proapoptotic proteins, such as MCL-1 and p53.
In vivo	Administration of WP1130 inhibits the growth of K562 tumors as well as both wildtype Bcr/Abl and T315I mutant Bcr/Abl-expressing BaF/3 cells transplanted into nude mice. Consistent with the down-regulation of c-Myc, this compound displays potent inhibitory activity against A375 melanoma tumors established in nude mice.
