Modifications of the GSK3β substrate sequence to produce substrate-mimetic inhibitors of Akt as potential anti-cancer therapeutics

Amplification, overexpression, and elevated activation of Akt have been detected in many human malignancies making it an important target for cancer therapy. The Akt substrate-binding site offers a large number of potential interactions to an appropriately designed small molecule and can form the basis for the development of selective inhibitors. Here, we report the progression of GSK3β substrate-mimetic inhibitors towards the development of a potent, small molecule substrate-mimetic inhibitor of Akt.
