title: Synthesis of feruloyl-myo-insitol derivatives and their inhibitory effects on phorbol ester-induced superoxide generation and Esptein-Barr virus activation.
abstract: We prepared 14 feruloyl-myo-inositol derivatives, and evaluated the relationships between their stereostructure and inhibitory activity toward the 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced superoxide (O(2)(-)) generation. And further, their suppressive effect on the TPA-induced Epstein-Barr virus (EBV) activation was examined in order to estimate their anti-carcinogenic potentials. Among the derivatives tested, 1,6-O-bis[3-(4'-hydroxy-3'-methoxyphenyl)-2-propenoyl]-myo-inositol (6b) showed an excellent suppressive activity on the O(2)(-) generation at a concentration of 20 microM. For the suppressive effects on the EBV activation, 2,4,6-O-tris[3-(4'-hydroxy-3'-methoxyphenyl)-2-propenoyl]-myo-inositol 1,3,5-orthoformate (9b) showed the highest activity at a concentration of 100 microM among the derivatives tested. These results suggest that the inhibitory potencies of feruloyl-myo-inositol derivatives depend on the stereostructure of molecules rather than the hydrophobicity of molecules.
