Novel flavagline analogues were synthesized and examined with respect to their cytotoxicity Structural features critical to the potential of this class of anticancer natural products wet e unraveled We demonstrated, in particular, that the introduction of substituants at C-2 has a deleterious effect on multidrug resistance Replacement of the hydroxy at C-1 by an aminoformyl with the opposite configuration enhances the cytotoxicity and led to a compound that reduces tumors growth in an allograft model at nontoxic doses

Synthetic Analogue of Rocaglaol Displays a Potent and Selective Cytotoxicity in Cancer Cells: Involvement of Apoptosis Inducing Factor and Caspase-12
Flavaglines constitute a family of natural anticancer compounds. We present here 3 (FL3), the first synthetic flavagline that inhibits cell proliferation and viability (IC50 approximate to 1 nM) at lower doses than did the parent compound, racemic rocaglaol. Compound 3 enhanced doxorubicin cytotoxicity in HepG2 cells and retained its potency against. adriamycin-resistant cell lines without inducing cardiomyocyte toxicity. Compound 3 induced apoptosis of HL60 and Hela cells by triggering the translocation of Apoptosis Inducing Factor (AIF) and caspase-12 to the nucleus. A fluorescent conjugate of 3 accumulated ill endoplasmic reticulum (ER), suggesting that flavaglines bind to their target in the ER. where it triggers a cascade of events that leads to the translocation of AIF and caspase-12 to the nucleus and probably inhibition of eIF4A. Our studies highlight structural features critical to their antineoplastic potential and suggest that these compounds would retain their activity in cells refractory to caspase activation.
