DMU-212, a methoxylated resveratrol analog, has significant anticancer activity, and selectively
targets tumor cells. A library of E-diarylstilbenes structurally related to DMU-212 has been synthesized
and evaluated for anticancer activity against a large panel of 45 human cancer cell lines.
From this study, DMU-212 (3a) exhibited an average growth inhibitory effect (GI50) of 3.5 M
against all the human cancer cell lines in the panel, and was particularly effective against the four cancer
cell lines: SNB-75 (CNS), MDA-MB-435 (melanoma), A498 (renal), and MCF7 (breast), with
GI50 values of 1.88, 1.04, 0.74 and 1.66 µM, respectively. Also, the 4’-chloro analog of DMU-212, 3d,
exhibited 98 and 80 percent growth inhibition against MDA-MB-435 (melanoma) and K-562 (leukemia) cancer cell lines
at a concentration of 10 M. Further investigation of DMU-212 and its analogs may provide novel therapeutic avenues for
treatment of a variety of human cancers.
cis-Stilbenes were synthesized from trans-cinnamic acids, involving ethylenic-bond bromination and a subsequent one-pot microwave-promoted stereoselective debrominative decarboxylation-Suzuki cross-coupling strategy. This sequence represents a useful way to prepare a variety of combretastatin A-4 derivatives.

6-exo/endo-Trig intramolecular additions of aryl radicals to electron-rich, unsubstituted and electron-deficient arenes have all been shown to proceed efficiently to give the corresponding phenanthrenes in high yield.

(Z)-stilbenoid combretastatin A4, have been considered as promising lead compounds for the development of anticancer drugs. The antitumour properties of stilbenoids are known to be modulated by cytochrome P450 enzymes CYP1A1 and CYP1B1, which contribute to extrahepatic phase I xenobiotic and drug metabolism. Thirty-four methyl ether analogues of resveratrol were synthesised, and their anticancerproperties were
