145317-11-9

Ro 31-8425 (145317-11-9) is a selective, reversible, ATP-competitive inhibitor of protein kinase C. Inhibits PKCα, β1, β2, γ and ε, IC50= 8, 8, 14,13 and 39 nM respectively.1? Extremely useful tool for probing PKC-dependent physiology2 or signaling pathways3. Increases MSC adhesion to an ICAM-1 coated substrate in vitro and enables targeted delivery of systematically administered MSCs to inflamed sites in vivo in a CD11a-dependent manner.4? Cell permeable.

Bisindolylmaleimide X hydrochloride is a potent and selective cell-permeable protein kinase C (PKC) inhibitor. Studies reveal that inhibition of PKCα by Bisindolylmaleimide X and other similar PKC inhibitors has been associated with enhanced cardiac contractility and protection from heart failure.
