Synthesis of 4′-ester analogs of resveratrol and their evaluation in malignant melanoma and pancreatic cell lines

4′-Ester analogs of the disease preventative agent resveratrol were synthesized and evaluated for their potential as anti-melanoma and pancreatic cancer agents. A decarbonylative Heck coupling was used to assemble the protected stilbene core structure. Th

Novel Sirtuin Activating Compounds and Methods for Making the Same

The present invention includes methods for preparing resveratrol, resveratrol esters and substituted and unsubstituted stilbenes of the formula given below; where each Y is —O or halogen, each Z is —O or halogen, each n and each m is independently the value of 0, 1, 2, 3, 4 or 5, each A and each B is independently selected from Pn, R or absent, each V and each W is independently selected from Pn, straight or branched alkyl of from (2) to (6) carbon atoms and cycloalkyl of from (3) to (8) carbon atoms, alkoxy, phenyl, benzyl or halogen, R is independently selected from the group comprising alkyl with at least one carbon atom, aryl and aralkyl, Pn is an alcohol protecting group and diastereoisomers of the foregoing. The compounds are made from a multi-step process including a N-heterocyclic carbon-type ligand coupling in the presence of a base with benzyol halide and styrene coupling partners. These compounds show increased stability for use in the food, cosmetic and pharmaceutical industries.

Synthesis of polyhydroxylated ester analogs of the stilbene resveratrol using decarbonylative Heck couplings

Protected 3,5-hydroxy-benzoyl chlorides 3 were coupled with styrenes 4 to give hydroxylated stilbenes, analogs of resveratrol, an important antioxidant disease preventative agent isolated from grape skins and other dietary sources. Levulinate and chloroacetate protecting groups allowed for the selective production of mono- and di-acetate variations under palladium-N-heterocyclic carbene (NHC) catalyzed decarbonylative coupling conditions. Fluorinated analogs were also produced using Heck conditions with bromofluorobenzenes. Human HL-60 cell assays showed the 4′-acetoxy variant 11 to have improved activity (ED50 17 μM) relative to resveratrol (24 μM).
