Cell lines | HEL cells carrying the mutant JAK2 V617F isoform |
Preparation method | The solubility of this compound in DMSO is >17.8 mg/mL. General tips for obtaining a higher concentration: Please warm the tube at 37 ℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below - 20 ℃ for several months. |
Reacting condition | 0 ~ 6 μM; 72 hrs |
Applications | In HEL cells carrying the mutant JAK2 V617F isoform, WP1066 markedly inhibited cell growth in a dose-dependent manner, with the IC20, IC50 and IC80 values of 0.8, 2.3 and 3.8 μM, respectively. At the concentrations of 0.5, 1.0, 2.0, 3.0 and 4.0 μM, WP1066 inhibited phosphorylation of JAK2, STAT3, STAT5 as well as ERK1/2, without affecting phosphorylation of JAK1 and JAK3. |
Animal models | Nude mice bearing Caki-1 cells |
Dosage form | 40 mg/kg; p.o.; q.d., 5 days on and 2 days off for 19 days |
Applications | In nude mice bearing Caki-1 cells, WP1066 significantly inhibited tumor growth. The immunohistochemical analysis results of Caki-1 xenograft tumors showed that there was little p-STAT3 immunostaining in the WP1066 treatment group which had similar total STAT3 immunostaining as the vehicle group. The results suggested that WP1066 inhibited STAT3 phosphorylation without altering STAT3 expression. |
Other notes | Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |

| 产品描述 | WP1066, an analogue of AG490, is a novel and potent inhibitor of janus kinase 2 (JAK2), which inhibits the phosphorylation of JAK2 and degrades JAK2 protein consequently blocking JAK2’s downstream signal transducer and activator of transcription (transcription-3 and transcription-5) as well as phosphoinositide-3-kinase pathways in a dose- and time-dependent manner. Results of preliminary studies suggest that WP1066 inhibits the growth of xenograft tumors generated from Caki-1 renal carcinoma cells (RCC) suppressing tumor angiogenesis and exhibits antiproliferative activity in AML colony-forming cells from newly diagnosed AML patients as well as in AML cell lines OCIM2 and K562, which potentiates it to treat RCC, acute myeloid leukemia (AML) and other hematologic maglignancies.
