Objective To design and synthesize diphenylmethyl sulfinyl acetamides with anti-fatigue activities.Methods The structures of target compounds,which were synthesized from diphenylmethylthio-acetic acid via condensation and oxidation,were designed with modafinil as the lead compound.The extent to which target compounds ameliorated exercise-induced fatigue in mice was evaluated by means of a mouse rotary rod fatigue meter.Results Target compounds C_(1)-C_(10) were synthesized and their structures were confirmed by ^(1)H-NMR,^(13)C-NMR and HRMS.C_(1),C_(3),C_(5) and C_(8) showed significant anti-fatigue activities compared to blank control.Conclusion The synthesis method of target compounds requires easily available materials,mild conditions and simple procedures,and four compounds show significant anti-fatigue activities,which provides reference for further study on the design,synthesis and anti-fatigue activities of molecules with similar structures.
