Background
AZD1480 is a novel small-molecule JAK inhibitor. It is able to block cell proliferation and induce apoptosis of myeloma cell lines. It can effectively inhibit tumor angiogenesis and metastasis mediated by STAT3 in stromal cells as well as tumor cells. AZD1480 has broad efficacy on a wider variety of myeloma cells, such as RPMI 8226, OPM-2, NCI-H929, Kms.18, MM1.S and IM-9, as well as primary myeloma cells. AZD1480 induces cell death of Kms.11 cells grown in the presence of HS-5 bone marrow (BM)-derived stromal cells and inhibits tumor growth in a Kms.11 xenograft mouse model, accompanied with inhibition of phospho-FGFR3, phospho-JAK2, phospho-STAT3 and Cyclin D2 levels. AZD1480 also demonstrates important Jak2 selectivity over Jak3, in particular at high ATP concentrations and marginal selectivity over Jak1 at Km ATP.

Applications
|
In the AZD1480 combined with cisplatin treatment groups, cisplatin could inhibit the proliferation of SKOV3 cells with dose dependent (P<0.05).There was no significant difference between 1 μmol/L AZD1480 group and control group (P >0.05) butwas statistically significant difference 5 μmol/L and 10 μmol/L AZD148 groups compared with the control group (P<0.05). The Coefficient ofdruginteraction (CDI) values were (0.902, 0.914, 0.95, 0.893, 0.848, 0.974, 0.923,0.767, 0.372) <1, which confirmed that these two drugs were synergistic. CDI value was 0.372 when the concentration was80μg/ml cisplatin + 10 μmol/L AZD1480,which showed that their synergistic effects were very significant.

Applications
|
The tumor growth in AZD1480-treated group was significantly depressed compared to control in each cell line. Tumors from mice treated with AZD1480 had decreased levels of tyrosine phosphorylated STAT3 as well as of STAT3 downstream targets (CyclinD1,-3, Bcl-2 and Survivin) compared to the levels in tumors from mice receiving vehicle. This shows that AZD1480 treatment induces the inhibition of STAT3 activity and its target gene expression in vivo.

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.
