摘要:Itz-1 Is A Chondroprotective Agent That Inhibits Interleukin-1 Beta-Induced Matrix Metalloproteinase-13 (Mmp-13) Production And Suppresses Nitric Oxide-Induced Chondrocyte Death. Here We Describe Its Mechanisms Of Action. Heat Shock Protein 90 (Hsp90) Was Identified As A Specific Itz-1-Binding Protein. Almost All Known Hsp90 Inhibitors Have Been Reported To Bind To The Hsp90 N-Terminal Atp-Binding Site And To Simultaneously Induce Degradation And Activation Of Its Multiple Client Proteins. However,Within The Hsp90 Client Proteins,Itz-1 Strongly Induces Heat Shock Factor-1 (Hsf1) Activation And Causes Mild Raf-1 Degradation,But Scarcely Induces Degradation Of A Broad Range Of Hsp90 Client Proteins By Binding To The Hsp90 C Terminus. These Results May Explain Itz-1'S Inhibition Of Mmp-13 Production,Its Cytoprotective Effect,And Its Lower Cytotoxicity. These Results Suggest That Itz-1 Is A Client-Selective Hsp90 Inhibitor.
