Abstract

The synthesis and biochemical characterization of AX4697, a fluorescent, bisindolylmaleimide-derived probe for PKCalpha and beta, is described. AX4697 was able to quantify changes in PKC expression in drug-treated Jurkat cells and was shown to covalently label PKCalpha on C619, a residue that sits just outside the active site.
