Design and synthesis of marine fungal phthalide derivatives as PPAR-γ agonists
摘要:
On the basis of a marine fungal phthalide (paecilocin A) skeleton, we synthesized 20 analogs and evaluated them for peroxisome proliferator-activated receptor gamma (PPAR-gamma) binding and activation. Among these analogs, 6 and 7 had significant PPAR-c binding activity, and 7 showed further PPAR-gamma activation in rat liver Ac2F cells. In docking simulation, 7 formed H bonds with key amino acid residues of the PPAR-gamma binding domain, and the overall positioning was similar to rosiglitazone. This new phthalide derivative is considered an interesting new molecular class of PPAR-gamma ligands. (C) 2012 Elsevier Ltd. All rights reserved.
