Stilbene is a versatile scaffold characterized by two aromatic rings linked by an ethylene bridge. Stilbenes are defense compounds produced by some plants in response to pathogen attack and other stresses. Stilbene-containing compounds, as resveratrol, are abundant in natural products, with a variety of important biological activities such as antioxidant, hypolipidemic, antiviral and antiinflammatory. In the last decade, natural compounds with stilbene backbone demonstrated to possess promising activity in cancer prevention, targeting a wide variety of intracellular pathways. In order to overcome the unfavorable pharmacokinetic of resveratrol, different substituents were introduced on one or both aromatic rings and numerous hybrid derivatives have been synthesized and tested on different biological targets. There are clinically used drugs featured by the presence of stilbene nucleus. Starting from these data, our studies explored the potential of synthetic compounds containing the stilbene scaffold (Figure) on crucial biological processes, such as the modulation of PPAR nuclear receptor activities. We further explored the effects of the above mentioned compounds on different pathological processes, including cancer. This talk focuses on the synthesis and biological activities of compounds that contain stilbene:- hybrids constituted by a 4-substituted stilbene moiety and different alkanoic chains, active as agonists on PPARs and antioxidant on mouse myoblast C2C12 and breast cancer MCF7 cell lines;- stilbene-phenols with different substitution patterns on aromatic rings, active on C2C12 and pancreatic tumor cell lines;- stilbene-sulfonates and sulfonamides potentially active as aromatase inhibitors.
