ABSTRACT
Aim To explore the novel anti-fatigue a-gents targeting AMPA receptor. Methods Three ben-zoic acids of different methoxy substitutions were em-ployed, including piperonylic acid, 3,4,5-trimethoxy benzoic acid and 3,4-dimethoxy benzoic acid, which as mother nucleus and cyclic aliphatic amine or pheny-lpiperazine derivatives were introduced to modify the nitrogen atoms connecting to amino bonds. Forty-three compounds were synthesized and identified by 1 H-NMR. MTT assay, then pentobarbital induced hypno-sis experiment and mice burden swimming experiment were applied respectively to evaluate the new synthesized compounds’ cytotoxicity, CNS excitability and anti-fatigue activity. Results Compound 2j had low cytotoxicity,presenting certain central excitability and significant advantages on anti-fatigue. Conclusion The further development of compounds 2j with good anti-fatigue activities could be cultivated in further study.
ABSTRACT
[Objective] To observe the effects of Yun-Pi Prescription of different doss on endurance of rats with splenic asthenia and to explore the mechanism of Yun-pi Prescription in treatment of children apositia.[Methods] To set up the animal model of splenic asthenia with reserpine.Experimental rats were randomly divided into six groups:the control group,the model group,the positive control group.Xiao Shi Jian Er Syrup,and Yun-Pi Prescription treatment groups including high,middle and low dose.Changes of body weight,food intake and swimming time were measured to determine the endurance of rats.[Results] Yun-Pi Prescription could increase body weight and food intake,prolong the swimming time of splenic asthenia rats.[Conclusion] Yun-Pi Prescription could effectively counteract fatigue and improve endurance of rats with splenic asthenia and it is useful in treatment rats with splenic asthenia.
