PI3Kα has been identified as an ideal target to treat with PIK3CA gene mutation disease, including drugs such as Alpelisib and Copanlisib. Five purine analogues and four thiazole analogues were designed and synthesized. Their enzymaticactivity against PI3Ka/β/γ/δ were tested, respectively. All compounds showed excellent selectivity in modulating PI3Ka activity, and parts of the compounds showed good inhibition. Meanwhile, we used Autodock 4.2 to explore the binding mode of the most potential compound Tg with the target protein. In addition, DFT was used to calculate the HOMO-LUMO maps of the compounds Tf, Tg and positive control. This paper will provide some useful information for further drug design of PI3Kα inhibitors.
