2-Benzyl and 2-phenyl-3-hydroxypropyl pivalates as protein kinase C ligands

A series of 2-benzyl and 2-phenyl-3-hydroxypropyl pivalates designed to incorporate the principal pharmacophores of phorbol esters have been synthesized and tested as PKC-α ligands. Among the analogues, 13c exhibited the most potent binding affinity with a Ki = 0.7 μM. The synthesized analogues were subjected to molecular modeling analysis based on two alternative models of the phorbol pharmacophore and a docking study of 13c was carried out.
