A successful kinetic resolution of a racemic mixture of delta-hydroxy esters 1 was obtained via lipase-catalyzed transesterification (E value up to 360). The combination of the enzymatic kinetic resolution with a ruthenium-catalyzed alcohol racemization led to an efficient dynamic kinetic resolution (ee up to 99% and conversion up to 92%). The synthetic utility of this procedure was illustrated by
The invention relates to nitric oxide donors of the formula (I) and pharmaceutically acceptable salts or stereoisomers thereof : wherein A and A' are independently selected from the group consisting of H and -(X)s-Y with the proviso that at least one of A or A' is not H; wherein s is 0 or 1; X is selected from the group consisting of : -CO-, -COO-, -CONH- and -SO2- or (A); Y is straight or branched C1-C20 alkyl chain, preferably C1- C10 alkyl chain, substituted with one or two -ONO2; or C1-C6 alkylenoxy- C1-C5 alkyl wherein the alkyl group is substituted by one or two -ONO2 groups. The invention also provides novel compositions comprising at least one compound of the invention and at least one therapeutic agent.
Nitroderivatives of prostaglandins having improved pharmacological activity and enhanced tolerability are described. They can be employed for the treatment of glaucoma and ocular hypertension.
