Ro 31-8220 methanesulfonate

Ro 31-8220 Mesylate is a protein kinase C (PKC) inhibitor.

ChEBI: Ro 31-8220 is an imidothiocarbamic ester, a member of indoles and a member of maleimides. It has a role as an EC 2.7.11.13 (protein kinase C) inhibitor. It is functionally related to a maleimide.

Protein kinase C inhibitor, with activity at other protein kinases (IC 50 values are 33, 3, 8, 15 and 38 nM for PKC α , MAPKAP-K1b, MSK1, GSK3 β and S6K1 respectively). Activates JNK and glycogen synthase, and inhibits MAPK and ERK2, in rat adipocytes and L6 myotubes. Also inhibits voltage-dependent Na + channels in the micromolar range.

PKC-α: 5 nM (IC₅₀); PKC-βII: 14 nM (IC₅₀); PKC-βI: 24 nM (IC₅₀); PKC-ε: 24 nM (IC₅₀); PKC-γ: 27 nM (IC₅₀); Rat Brain PKC: 23 nM (IC₅₀); MAPKAP-K1b: 3 nM (IC₅₀); MSK1: 8 nM (IC₅₀); S6K1: 15 nM (IC₅₀); GSK3β: 38 nM (IC₅₀)
