The oxidation of chalcone 1 to optically active epoxide 2 [a precursor of (+)-clausenamide (+)-3] may be effected using a 15-mer or 20-mer of L-leucine bound to a PEG based support; poly-L-leucines of this type may be used as immobilised catalysts in a fixed-bed reactor.

The present invention provides compositions and methods for the treatment of central nervous system damage in a subject. More particularly, the invention provides a combination therapy for the treatment of a central nervous system ischemic condition or a central nervous system traumatic injury comprising the administration to a subject of a potassium ion channel modulator in combination with a cyclooxygenase-2 selective inhibitor.
