ABSTRACT
Objective To design and synthesize schisandrone derivatives for the therapy of disease like AD,and to meas-ure their anti-oxidation activity.Methods Ten compounds were synthesized,and seven of them were first reported.The influ-ence all the compounds on SOD from the mouse serum were measured to evaluate anti-oxidation activity.Structure-activity rela-tionship(SARs)were also discussed.Results Compounds 2,3,5 and 8 could increase the activity of SOD in mouse serum.Fur-thermore,Compounds 2,3 and 5 showed better activities than schisandrone.Conclusion Synthesized schisandrone derivatives showed anti-oxidation activity.The SARs demonstrated the carbonyl of C-1 position and the methyls of C-2 and 3 had no influ-ences to the anti-oxidant activity.
