Mechanism of Action

Features	Similar to its parent compound AG490, WP1066 inhibits the phosphorylation of JAK2, but unlike AG490, WP1066 also degraded JAK2 protein.
Targets/IC₅₀/Ki	JAK2 (HEL cells) 2.3 μM STAT3 (HEL cells) 2.43 μM
In vitro	WP1066 markedly inhibits the growth of HEL cells carrying the JAK2 V617F mutant isoform in a dose-dependent manner with IC20, IC50 and IC80 of 0.8, 2.3 and 3.8 μM. This compound at concentrations of 0.5, 1.0, 2.0, 3.0, or 4.0 μM inhibits the phosphorylation of JAK2, STAT3, STAT5, and ERK1/2 without affecting the phosphorylation of JAK1 and JAK3 in erythroid leukemia HEL cells that express the JAK2 V617F isoform. It at concentrations ranging from 0.5 to 3.0 μM inhibits the proliferation of AML colony-forming cells obtained from patients and that of the AML cell lines OCIM2 and K562 in a dose-dependent manner. This chemical at concentrations of 0.5, 1.0, 2.0, 3.0, or 4.0 μM dose-dependently decreases JAK2 and pJAK2 protein levels as well as downstream phosphorylation levels of STAT3, STAT5, and AKT in OCIM2 and K562 cells. It at concentrations of 2 μM inhibits OCIM2 cell multiplication by inducing accumulation of cells at the G0-G1 phase of the cell cycle. This compound at concentrations of 1, 2, or 3 μM induces apoptosis in both OCIM2 and K562 cells in a dose-dependent fashion by activating procaspase-3 and cleaving PARP. It at concentrations of 5 μM prevents the phosphorylation of STAT3, and at concentrations of 2.5μM it significantly inhibits cell survival and proliferation in Caki-1 and 786-O renal cancer cells. This chemical at concentrations of 5 μM suppresses HIF1α and HIF2α expression and VEGF production in Caki-1 and 786-O renal cancer cells.
In vivo	WP1066 orally administrated at dose of 40 mg/kg once daily for 19 days significantly inhibits the tumours growth in Caki-1 xenograft mice, with decreased immunostaining of phosphorylated STAT3 and reduced length of CD34-positive vessels.
