Ro-31-8220

A cell-permeable, competitive, reversible, and selective inhibitor of protein kinase C (PKC; IC₅₀ = 10 nM) over CaM kinase II (IC₅₀ = 17 µM) and protein kinase A (IC₅₀ = 900 nM). Potently inhibits GSK-3 in primary adipocytes (IC₅₀ = 6.8 nM) and in GSK-3β immunoprecipitates (IC₅₀ 2.8 nM). An inhibitor of MAP kinase phosphatase-1 expression and an activator of JNK1. Inhibits the phosphorylation of Raf-1 and induces apoptosis, independent of its effects on PKC, in HL-60 cells. Also inhibits sirtuin in a NAD-competitive manner (IC₅₀ = 3.5 µM and 0.8 µM for SIRT1 and SIRT2, respectively), and induces hyperacetylation of tubulin in A549 cells.
