The present invention provides peptide-based phosphorylation catalysts (PBPC's)
for the asymmetric monophosphorylation of cyclitols, particularly myo-inositols.
The PBPC's of the invention effect a regio and enantioselective phosphorylation
of a myo-inositol in a manner analogous to enzymatic kinases, thereby functioning
as effective "kinase mimics." Although orders of magnitude less complex in terms
of structure than macromolecular proteins, the PBPC's of the invention control
product formation with high enantioselectivity (98% ee). The synthetic (+)-myo-inositol-1-phosphate
is optically and spectroscopically equivalent to naturally occuring compound. The
ability of the low molecular weight PBPC's of the present invention to mimic stereoselective
enzymes represents a powerful approach toward catalytic asymmetric synthesis of
biologically important molecules, and for mechanistic modeling of biochemical transformations
to enable their use in drug applications.
