AZD5363 is a highly potent adenosine triphosphate (ATP)-competitive AKT inhibitor with
IC50<10nmol/l for all three AKT isoforms.
AZD5363 is well designed to inhibit the important main signal pathway in various human
cancer. AZD5363 is a specific inhibitor of the AKT pathway which is activated in a wide
spectrum of tumours.The combination of AZD5363 to standard chemotherapy, paclitaxel, might
improve the outcomes of 2nd line therapy in advanced gastric cancer patients .
