General description

A selective cell-permeable protein kinase C inhibitor. Displays about 10-fold greater selectivity for PKCα (IC50 = 9 nM) and 4-fold greater selectivity for PKCβI (IC50 = 28 nM) over PKCε (IC50 = 108 nM). Also prevents T cell-driven chronic inflammatory responses in vivo.

Please note that the molecular weight for this compound is batch-specific due to variable water content.

Tau is a microtubule-associated protein, found at high levels in neurons, and its aggregation is associated with neurodegeneration. Recently, it was found that tau can be actively secreted from neurons, but the effects of extracellular tau on neuronal viability are unclear.
