  • Patent number: 8853270
    Abstract: The present invention relates to stilbene and quinine compounds related to combretastatin A-4 and their use as anticancer compounds and prodrugs. The compounds include those with an alkyl group on the double bond of cis- or trans-stilbenes, compounds with one or more (and preferably 2 or 3) alkyl group substituents on the stilbene A ring, compounds with an alkoxy group other than methoxy at position 3, 4, and/or 5 of the stilbene A ring, compounds (or prodrugs) in which BBOC amino acid esters are formed with the phenolic hydroxyl at the 3-position of the B ring and compounds (or prodrugs) based on a benzoquinone B ring. The present invention further relates to the photochemical reactions of stilbene compounds, either the above compounds disclosed for the first time herein or compounds based on prior stilbenes.

  • Publication number: 20040143023
    Abstract: The present invention relates materials and methods for synthesizing stilbenes, and in particular to processes for the synthesis of substituted stilbenes such as combretastatin A4. The present invention relates in particular to methods which are stereoselective for either the cis or the trans isomer of the substituted stilbene, using a Perkin-type condensation of an arylacetic acid and a substituted benzaldehyde, followed by a decarboxylation reaction to produce the substituted cis-stilbenes or a Suzuki-type reaction involving a Z or E-ethenyl halide and a substituted boronic acid in the presence of a palladium catalyst to produce specifically either the Z or E-isomer of substituted stilbenes.
