A series of trans- or cis-stilbenes have been synthesized in good to excellent yields via a functional group-dependent decarboxylation process from the corresponding 2,3-diaryl acrylic acids in a neutral CuI/1,10-phen/PEG-400 system under microwave conditions. The in situ generation of the recyclable catalytic complex, the use of environmentally benign solvent PEG-400, the operational simplicity, the short reaction times, as well as the functional group-dependent chemo- and stereo-selectivity have made the decarboxylation process a highly efficient and applicable protocol.

The substitutional effect in the selective synthesis of cis, trans stilbenes and 3-arylcoumarins has been described. The regio- and geometrical selectivity for synthesis of stilbene derivatives under the Perkin strategy strongly depends on the presence or absence of hydroxyl group as well as their positions in the phenyl ring. As a result, practical synthetic strategies were established for preparing various natural stilbenes including combretastatin A-4, pterostilbene, and resveratrol with satisfactory yields (49.2-63.7%).

A series of novel stilbene derivatives has been synthesized and studied with the main goal to investigate SAR of the amino compound 1a, as well as to improve its water solubility, a potentially negative aspect of the molecule that could be a serious obsta

Stilbene derivatives exhibit killing and suppression of growth activity against a variety of cancer cells, and are effective at suppressing tumor growth in vivo. The stilbene derivatives may be used in the treatment of diseases characterized by cell hyperproliferation including human malignancies and non-malignant diseases such as liver cirrhosis. Stilbenes may also disrupt abnormal vessels in tumor to achieve vascular disrupting effect to suppress tumor growth. Water soluble pro-drug forms of stilbene derivatives are particularly useful in suppressing tumor growth in vivo.

New carbon-11 and fluorine-18 labeled stilbene derivatives, cis-3,5-dimethoxy-4′-[11C]methoxystilbene (4′-[11C]8a), cis-3,4′,5-trimethoxy-3′-[11C]methoxystilbene (3′-[11C]8b), trans-3,5-dimethoxy-4′-[11C]methoxystilbene (4′-[11C]10a), trans-3,4′,5-trimethoxy-3′-[11C]methoxystilbene (3′-[11C]10b), cis-3,5-dimethoxy-4′-[18F]fluorostilbene (4′-[18F]12a), and trans-3,5-dimethoxy-4′-[18F]fluorostilbene (4′-[18F]13a), were designed and synthesized as potential PET probes for aryl hydrocarbon receptor (AhR) in cancers.

Resveratrol 1 (3,4′,5-trihydroxy-trans-stilbene), a phytoalexin present in grapes and other food products, has recently been suggested as a potential cancer chemopreventive agent based on its striking inhibitory effects on cellular events associated with cancer initiation, promotion, and progression. This triphenolic stilbene has also displayed in vitro growth inhibition in a number of human cancer cell lines. In this context, a series of cis- and trans-stilbene-based resveratrols were prepared with the aim of discovering new lead compounds with clinical potential. All the synthesized compounds were tested in vitro for cell growth inhibition and the ability to induce apoptosis in HL60 promyelocytic leukemia cells. The tested trans-stilbene derivatives were less potent than their corresponding cis isomers, except for trans-resveratrol, whose cis isomer was less active. The best results were obtained with compounds 11b and 7b, the cis-3,5-dimethoxy derivatives of rhapontigenin 10a (3,5,3′-trihydroxy-4′methoxy-transstilbene) and its 3′-amino derivative 10b, respectively, which showed apoptotic activity at nanomolar concentrations. The corresponding trans isomers 12b and 8b were less active both as antiproliferative and as apoptosis-inducing agents. Of interest, 11b and 7b were active toward resistant HL60R cells and their activity was higher than that of several classic chemotherapeutic agents. The flow cytometry assay showed that at 50 nM compounds 7b or 11b were able to recruit almost all cells in the apoptotic sub-G0-G1 peek, thus suggesting that the main mechanism of cytotoxicity of these compounds could be the activation of apoptosis. These data indicate unambiguously that structural alteration of the stilbene motif of resveratrol can be extremely effective in producing potent apoptosis-inducing agents.
