Abstract:
Six bifunctional molecules containing biotin and various inositol phosphates were synthesized. These compounds were designed on the basis of X-ray structures of the complexes of D-myo-inositol 1,4,5-triphosphates (IP(3)) and phospholipase C delta pleckstrin homology domain (PLCdelta PH) considering the application to the biotin-avidin techniques. The building blocks of the inositol moiety were synthesized starting with optically resolved myo-inositol derivatives and assembled to the biotin linker through a phosphate linkage.
