Description
A cell-permeable and reversible inhibitor of protein kinase C δ (PKCδ, IC50 = 3-6 µM) and PKCΘ isozymes. Also inhibits PKCα, PKCβ, and PKCγ isoforms, but with significantly reduced potency (IC50 = 30-42 µM). Has reduced inhibitory activity on PKCε, PKCη, and PKCξ (IC50 = 80-100 µM). Also known to inhibit CaM kinase III (IC50 = 5.3 µM)
