AMG900 is a highly sensitive and orally bioavailable inhibitor of Aurora Kinase with IC50 values of 5 nmol/L.
AMG900 is an inhibitor of all three aurora kinase family members. It was founded through the discovery of a new class of ATP-competitive phtha-lazinamine small molecule inhibitors of aurora kinases. AMG900 inhibits autophosphorylation of aurora-A and aurora-B in tumor cells, and also aborts cell division without a prolonged mitosis arrest and finally results cell death. It can inhibit 26 different tumor cell lines proliferation, meanwhile, it also has the ability to enhance other aurora kinase inhibitors' effective. [1, 2]
AMG900 had been tested in animal level using mice models. Mice bearing established HCT116 tumors and orally delivery AMG900. Comparing to the vehicle group, the experiment groups delivery AMG900 with different concentration showed an obvious smaller tumor volume. These results revealed that AMG900 has the ability to significantly inhibit tumor growth.
