【Abstract】 Objective:To explore the artificial synthesis of 2-amino-3-phenylpropanehydrazide on semicarbazide sensitive amine oxidase(SSAO)inhibitory effect. Methods:2-amino-3-phenylpropanehydrazide was synthesized,and identified by IR,MS and 1H-NMR. According to the inhibition curve of 2-amino-3-phenylpropanehydrazide against SSAO,the IC50 was calculated. Dialysis experiment was performed to determine the inhibition type of 2- amino-3-phenylpropanehydrazide against SSAO. Concentration of 2-amino-3-phenylpropanehydrazide was analyzed by high performance liquid chromatography. Results:IC50 of 2-amino-3-phenylpropanehydrazide against SSAO was 0.76 μmol/L. The concentration of 2-amino-3-phenylpropanehydrazide in dialysis liquid after dialysis was 0.07 μmol/L,with inhibitory ratio of 78.0%. Conclusion:2-amino-3-phenylpropanehydrazide is an irreversible inhibitor of SSAO.更多还原
