Abstract: The present invention is broadly directed to treatment of an addictive disease or disorder. In particular, the invention relates to inhibiting or reversing the biochemical and neurophysiological changes that correlate with behavioral changes of addictive diseases or disorders. The method of the invention comprises administering to a subject suspected of suffering from an addictive disease or disorder an amount of brain-derived factor (BDNF) or neurotrophin-4 (NT-4), or both, effective to reverse behavioral changes that are associated with the addictive disease or disorder. In a specific Example, administration of BDNF or NT-4 inhibits or reverses increased expression of tyrosine hydroxylase and glial ibrillary acidic protein in the ventral tegmental area of the brain, and inhibits or reverses increased levels of cyclic-AMP-dependent protein kinase activity in the nucleus accumbens.

Abstract: An ester is caused to act on a 2-substituted-3-hydroxycarboxylic acid ester as a racemate in the presence of hydrolase under substantially anhydrous conditions to effect a transesterification resulting in the resolution.The compound thus resolved is converted to an optically active 2,6-cis-2,5,6-substituted-1,3-dioxan-4-one and the resulting compound is recrystallized to give optically active 5,6-anti-2,5,6-substituted-1,3-dioxan-4-one and 5,6-syn-2,5,6-substituted-1,3-dioxan-4-one. Thus an optically active compound having plural chiral centers.Further, an optically active 2,5,6-substituted-1,3-dioxan-4-one obtained by transesterification and recrystallization is reacted with an alcohol to produce an optically active 2-substituted-3-hydroxycarboxylic acid ester.
