Several substituted cinnamylphenol (1,3-diphenylpropene) derivatives were synthesized and tested for their inhibitory activities against in vitro Epstein-Barr virus early antigen activation induced by 12-O-tetradecanoylphorbol-13-acetate in Raji cells. The prenylated cinnamylphenols were found to show remarkably potent activity. Furthermore, prenylated cinnamylphenols (19 and 25) exhibited a marked inhibitory effect on mouse skin tumor promotion in an in vivo two-stage carcinogenesis test. These results indicate that some prenylated cinnamylphenols might be valuable as potential cancer chemopreventive agents (anti-tumor promoters). (c) 2007 Elsevier Masson SAS. All rights reserved.

The synthesis of the racemates (±_-4-methoxydalbergione (IIIa) and (±)-3,4-dimethoxydalbergione (IIIb) has been achieved by Claisen rearrangements of the corresponding cinnamyl ethers (Ia and Ib) followed by Fremy's salt oxidation. These syntheses are based upon the biosynthetic schemes examined in Part II of this series.
