一种Akt的变构抑制剂。SC66 is an allosteric inhibitor of Akt that prevents binding of PIP3 to the PH domain. The compound prevents activation of Akt by PIP3, and also facilitates ubiquination and degradation of Akt. SC66 inhibition is maintained against a cancer relevant Akt mutation (E17K) that is resistant to the actions of PIP3K inhibitors. SC66 is active in vivo, and significantly inhibits the ability of HEK293T cells to form colonies in soft agar and tumor growth in nude mice.
