Biological Activity

Description Degrasyn (WP1130) is a selective deubiquitinase (DUB: USP5, UCH-L1, USP9x, USP14, and UCH37) inhibitor and also suppresses Bcr/Abl, also a JAK2 transducer (without affecting 20S proteasome) and activator of transcription (STAT). Degrasyn (WP1130) induces apoptosis and blocks autophagy.
Features WP1130 has an advantage in that its activity is not inhibited by a variety of Abl kinase mutations, including T315I.
Targets
DUB [1]
(Cell-free assay)		 Bcr-Abl [1]
(Cell-free assay)
1.8 μM
In vitro
In vitro

In addition to inducing rapid down-regulation of Bcr/Abl without affecting Bcr or c-Abl, 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, WP1130 induces down-regulation of Bcr/Abl within 60 minutes. WP1130 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. WP1130 (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. WP1130 is more effective in reducing leukemic cell colony formation compared with normal progenitor cells, and effective against primary leukemic cells harboring the T315I mutation. [1] WP1130 induces rapid proteasomal-dependent degradation of c-Myc protein in MM-1 multiple myeloma and other tumor cell lines, correlated with tumor growth inhibition. [2] Unlike AG490, WP1130 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. WP1130 (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.

Cell Research Cell lines BV173, BV173R, K562, and BaF/3
Concentrations Dissolved in DMSO, final concentrations ~10 μM
Incubation Time 72 hours
Method

Cells are treated with increasing concentrations of WP1130 (0.08-10 μM) in 96-well plates. Plates are incubated at 37 °C for 72 hours, after which 20 μL of MTT reagent is added, and the plates are incubated at 37 °C for another 2 hours. Cells are lysed with 100 μL lysis buffer (20% sodium dodecyl sulfate [SDS] in 50% N, N-dimethylformamide adjusted to pH 4.7 with 80% acetic acid and 1 M hydrochloric acid; final concentration of acetic acid is 2.5% and hydrochloric acid is 2.5%) and incubated for 6 hours. The optical density of each sample at 570 nm is determined with a SPECTRA MAX M2 plate reader.
In Vivo
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. [1] Consistent with the down-regulation of c-Myc, WP1130 displays potent inhibitory activity against A375 melanoma tumors established in nude mice. [2]
Animal Research Animal Models Swiss Nu/Nu mice transplanted with K562 tumor cells, BaF/3wt cells, or BaF/3/T315I cells
