However,The Requirement Of High Concentrations Warrants Chemical Optimization For Clinical Use. In This Study,Novel Naphthalene Derivatives With A Greater Chemical Chaperone Activity Than 4-Pba Were Synthesized With Analogy To The Benzene Ring. All Novel Compounds Showed Chemical Chaperone Activity,And 2 And 5 Possessed High Activity. In Subsequent Experiments,The Protective Effects Of The Compounds Were Examined In Parkinson'S Disease Model Cells,And Low Toxicity Of 9 And 11 Was Related To Amphiphilic Substitution With Naphthalene.
