Description: KP372-1 is a synthetic small molecule AKT inhibitor. KP372-1 is consisted of two isomers: KP372-1 A and KP372-1B. KP372-1 showed activities to block signalling downstream of Akt in thyroid tumour cells, leading to inhibition of cell proliferation and increased apoptosis. KP372-1 has also been shown to suppress cell proliferation and induce apoptosis in gliobastoma.
