Design of granulatimide and isogranulatimide analogues as potential Chk1 inhibitors: Study of amino-platforms for their synthesis.

The two marine alkaloids granulatimide and isogranulatimide have been shown to inhibit the checkpoint kinase 1 (Chk1), a promising target for cancer treatment. A molecular docking study allowing the design of new potential Chk1 inhibitors based on the natural products skeleton and the synthetic work to an amino-target platform to prepare them are described.
