The crossmetathesis of 1,2-epoxy-5-hexene (1) with methylacrylate and acrylonitrile was investigated as an entry to the synthesis of polyfunctional compounds. The resulting crossmetathesis products were hydrogenated in a tandem fashion employing the residual ruthenium from the metathesis step as the hydrogenation catalyst. Interestingly, the epoxide ring remained unreactive toward this hydrogenation

The present invention describes carbamic acid ester-derived and valeric acid ester-derived polyfunctional cross-linker molecules, and methods for their synthesis and use. The inclusion of polymeric moieties such as poly(alkylene oxide) in the cross-linkers of the present invention can provide advantageous solubility properties in aqueous environments. Such cross-linkers may be used to form conjugates for use in a variety of assay formats.

The present invention is generally drawn to novel isolated therapeutic agents, termed resolving, generated from the interaction between a dietary omega-3 polyunsaturated fatty acid (PUFA) such as eicosapentaenoic acid (EPA) or docosahexaenoic acid (DHA), cyclooxygenase-II (COX-2) and an analgesic, such as aspirin (ASA). Surprisingly, careful isolation of compounds generated from the combination of components in an appropriate environment provide di- and tri-hydroxy EPA or DHA compounds having unique structural and physiological properties. The present invention therefore provides for many new useful therapeutic di- or tri-hydroxy derivatives of EPA or DHA (resolvins) that diminish, prevent, or eliminate inflammation or PMN migration, for example. The present invention also provides methods of use, methods of preparation, and packaged pharmaceuticals for use as medicaments for the compounds disclosed throughout the specification.
