AT9283 is a multikinase inhibitor, is also a small-molecule inhibitor of several kinases with potential antineoplastic activity. Multikinase inhibitor AT9283 binds to and inhibits Aurora kinases A and B, JAK2 (Janus kinase 2) and the kinase BCR-ABL, which may result in the inhibition of cellular division and proliferation and the induction of apoptosis in tumor cells that overexpress these kinases. Aurora kinases are serine-threonine kinases that play essential roles in mitotic checkpoint control during mitosis; JAK2 is a kinase that transduces signals from the single chain and IL-3 cytokine receptor families, and from the IFN-gamma receptors; BCR-ABL is a fusion protein with tyrosine kinase activity that is commonly found in CML.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
