Outline
This study was conducted to design and synthetize highly efficient, specific, non-resistant small MEK inhibitors. Based on active small molecules which have been reported, we studied the action mode with MEK protein using Autodock 4.2, generated innovative and feasible design method, designed novel small MEK protein inhibitors with a reference to molecular modeling and docking. The anti-tumor activities of four kinds of cells including MCF-7, PANC-1, SY5Y, A549 were tested with MTT method in vitro. The structure of 10 new small molecules has been determined with 1H NMR and 13C NMR. The compounds 4, 6, 7, 8, 10 had high antitumor activities, the compounds 1, 3, 5 also showed good activity, and the compounds 2, 9 showed cell selectivity in killing tumor.
