1Enzymatic activity characterization of SARS coronavirus 3C-like protease by fluorescence resonance energy transfer technique显示文摘Aim: To characterize enzymatic activity of severe acute respiratory syndrome (SARS) coronavirus (CoV) 3C-like protease (3CL^pro) and its four site-directedmutants. Methods: Based on the fluorescence resonance energy transfer (FRET)principle using 5-[(2'-aminoethyl)-amino] naphthelenesulfonic acid (EDANS) and4-[[4-(dimethylamino) phenyl] azo] benzoic acid (Dabcyl) as the energy transferpair, one fluorogenic substrate was designed for the evaluation of SARS-CoV3CL^pro proteolytic activity. Results: The kinetic parameters of the fluorogenicsubstrate have been determined as Kin=404μmol·L^-1, kcat=1.08min^-1, and kcat/Km=2.7mmol^-1·L·min^-1. SARS-CoV 3CL^pro showed substantial pH and temperature-triggered activity switches, and site-directed mutagenesis analysis of SARS-CoV3CL^pro revealed that substitutions of His^41, Cys^145, and His^163 resulted in complete loss of enzymatic activity, while replacement of Met^162 with Ala caused strongly increased activity. Conclusion: This present work has provided valuable information for understanding the catalytic mechanism of SARS-CoV 3CL^pro. This FRET-based assay might supply an ideal approach for the exploration SARS-CoV 3CL^pro putative inhibitors.ShuaiCHEN Li-liCHEN Hai-binLUO TaoSUN,JingCHEN JingCHEN FeiYIE Jian-huaCAI Jing-kangSHEN XuSHEN Hua-liangJIANG 2005Acta Pharmacologica Sinica2005,26,1:3

7Activation of astroglial group Ⅱ and Ⅲ metabotropic glutamate receptors protects midbrain neurons against LPS or MPP^+ -induced neurotoxicity显示文摘AIM: Activation of glial metabotropic glutamate receptors (mGluRs) may be proved to play a critical role for neuroprotection in neurodegenerative diseases. Excess glutamate induced-excitoxicity is implicated in the initiation or progression of the neurodegenerative process.
