A series of 4-aminoquinazolines derivatives containing hydrophilic group were designed and identified as potent Pan-PI3K inhibitors in this study. The results of antiproliferative assays in vitro showed that this series of compounds had strong inhibition of tumor growth, especially compound 7b for MCF-7 cells but weak inhibition to normal cells. PI3K kinase assay showed that 7b had high activity for three PI3K isoforms with the IC50 values of picomole. The western blot assay indicated that 7b could decrease the phospho-Akt (S473) in a dose-dependent manner. Further experiments showed that 7b could induce apoptosis in MCF-7 cells. Four key hydrogen bonding interactions were found in the docking of 7b with PI3K kinase. All these results suggested that 7b is a potent PI3K inhibitor and could be considered as a potential candidate for the development of anticancer agents.

This paper describes the discovery and development of a flexible route to two candidate drug molecules by a common intermediate approach. Key reactions include Negishi and Suzuki couplings to form biaryl bonds. Conditions for a Miyaura borylation of heteroaryl bromides were also developed. Heteroaryl trifluoroborates and aryl chlorides were used as coupling partners in the Suzuki reaction, thereby minimizing detrimental side reactions such as protodeboronation and oxidative homocoupling. A complementary set of reaction conditions using pinacolboronates with potassium bifluoride as an additive were also developed and used to make 5 kg of drug substance for use in early-phase clinical trials.
