IC50: 30-60 nM for thyroid cancer cells

KP372-1 is a specific Akt inhibitor.

The phosphatidylinositol 3' kinase (PI3K)/phosphatase, which is a key regulator of cell proliferation and survival, is mutated or activated in various cancers. Akt seems to be a key central node in this pathway and therefore is an promising target.

In vitro: A previous study found that KP372-1 could block signalling downstream of Akt in thyroid tumour cells, resulting in inhibition of cell proliferation and increased apoptosis [1]. Another study showed that KP372-1 directly inhibited the kinase activity of AKT, FLT3, and PDK1concentration-dependently. Western blot analyses indicated KP372-1 decreased the phosphorylation of AKT on both Ser(473) and Thr(308). Moreover, the treatment of AML cell lines with KP372-1 led to rapid generation of reactive oxygen species and stimulation of oxygen consumption. In addition, KP372-1 was able to induce pronounced apoptosis in AML cell lines and primary samples irrespective of their FLT3 status, but not in normal CD34(+) cells [2].

In vivo: Up to now, there is no animal in vivo data reported.

Clinical trial: So far, no clinical study has been conducted.
