Importance of the backbone conformation of (-)-ternatin in its fat-accumulation inhibitory activity against 3T3-L1 adipocytes

Abstract

Key relationships between the intramolecular H-bond-derived backbone conformation and the bioactivity of the novel fat-accumulation inhibitor (-)-ternatin are examined by analyses of the NMR spectroscopic data and CD spectra of designed analogues. The results reveal that the beta-turn structure of (-)-ternatin is responsible for its potent fat-accumulation inhibitory effect against 3T3-L1 murine adipocytes.
