AZD1480 (AZD-1480) is a selective, orally bioavailable and ATP-competitive inhibitor of JAK2 (Janus-associated kinase) with potential antitumor activity. It inhibits JAK2 with an IC50 of 0.26 nM in a cell-free assay. It shows potent in vitro antiproliferative activity and high in vivo antitumor efficacy, because JAK2 is upregulated/mutated in a variety of cancer cells, mediating STAT3 activation and playing a key role in tumor cell proliferation and survival.

Biological Activity
| ln Vitro | By blocking Aurora kinase, AZD-1480 (5 μM) causes G2/M arrest and cell death [1]. Strongly inhibiting proliferation, survival, FGFR3 and STAT3 signaling, as well as downstream targets such cyclin D2, in human multiple myeloma cells is AZD-1480. In myeloma cell lines, AZD-1480 causes apoptosis and inhibits cell proliferation at low micromolar doses [2]. In human and mouse glioma cells, AZD-1480 can efficiently inhibit constitutive and stimulus-induced phosphorylation of JAK1, JAK2, and STAT-3, which reduces cell proliferation and induces apoptosis [3]. As a strong competitive small molecule inhibitor of JAK1/2 kinase, AZD-1480 reduces tumor development and STAT3 phosphorylation in a manner that is dependent on STAT3. By altering the tumor microenvironment, AZD-1480 partially prevents tumor angiogenesis and metastasis [4]. |
| ln Vivo | In multiple myeloma xenograft models and human solid tumors, AZD-1480 suppresses STAT3 phosphorylation [1]. AZD-1480 prolongs mouse life in vivo by preventing subcutaneous tumors from growing. By suppressing STAT-3 activity, it prevents intracranial glioblastoma (GBM) tumors, indicating AZD-1480's impact on the JAK/STAT-3 pathway. In research involving patients with GBM tumors, pharmacological inhibition must to be taken into account [3]. AZD-1480 prevents myeloid cell infiltration into the lungs and the development of lung metastases in models of spontaneous metastasis and syngeneic experimental mice. In addition, AZD-1480 decreases metastasis and angiogenesis in tumor models derived from human xenografts [4]. Human solid tumor xenografts with prolonged Stat3 activation are not able to grow when exposed to AZD-1480 [5]. |

| Additional Infomation |
AZD1480 has been used in trials studying the treatment of Solid Malignancies, Post-Polycythaemia Vera, Primary Myelofibrosis (PMF), and Essential Thrombocythaemia Myelofibrosis. JAK2 Inhibitor AZD1480 is an orally bioavailable inhibitor of Janus-associated kinase 2 (JAK2) with potential antineoplastic activity. JAK2 inhibitor AZD1480 inhibits JAK2 activation, leading to the inhibition of the JAK/STAT (signal transducer and activator of transcription) signaling including activation of STAT3. This may lead to induction of tumor cell apoptosis and a decrease in cellular proliferation. JAK2, often upregulated or mutated in a variety of cancer cells, mediates STAT3 activation and plays a key role in tumor cell proliferation and survival. |
