Protein Kinase C (PKC)

Staurosporine is a natural product originally isolated in 1977 from the bacterium Streptomyces staurosporeus. The main biological activity of staurosporine is the inhibition of protein kinases through the prevention of ATP binding to the kinase. This is achieved through the stronger affinity of staurosporine to the ATP-binding site on the kinase.

Sotrastaurin is a protein kinase C inhibitor for the prevention of transplant rejection and treatment of psoriasis.

Ruboxistaurin (LY333531) is a potent, selective inhibitor of Protein Kinase C isozymes, PKC β I(IC50=4.7 nM) and PKC β II (IC50=5.9 nM).

Go6976 is a potent PKC inhibitor with IC50 of 7.9 nM, 2.3 nM, and 6.2 nM for PKC (Rat brain), PKCα, and PKCβ1, respectively. Also a potent inhibitor of JAK2 and Flt3.

(-)-Indolactam V is a protein kinase C activator, which strongly directs human ES cell-derived definitive endoderm into pancreatic endoderm.

alpha-Amyloid Precursor Protein Modulator is a cell-permeable benzolactam derived PKC activator (Ki = 11.9 nM for PKCα) that efficiently enhances non-amyloidogenic α-processing of amyloid precursor protein (APP) even at 100 nM in human fibroblas.

GF 109203X is a potent and selective inhibitor of protein kinase C, selective for the α and β1 isoforms (IC50 values are 0.0084, 0.0180, 0.210, 0.132, and 5.8 μM for α, β1, δ, ε and ζ isoforms respectively). Selective over MLCK, PKG and PKA (IC50 values are 0.6, 4.6, and 33 μM respectively). Potent antagonist at the 5-HT3 receptor (Ki = 29.5 nM).

Ro 31-8220 mesylate is a PKC-inhibitor, which inhibits stimulated fluid pinocytosis of human PMNs induced by the PKC-activators phorbol myristate acetate (PMA, IC50 = 1.35 x 10(-6) M) or diacylglycerols (OAG, diC8) by 95%.

Valrubicin is a semisynthetic derivative of the antineoplastic anthracycline antibiotic doxorubicin.

12-O-tetradecanoyl phorbol-13-acetate is a diester of phorbol and is a tumor promoting compound extracted from croton oil. It is a reversible, highly potent protein kinase C (PKC) activator in vitro and in vivo at nM concentrations.

Protein Kinase C (19-31), this peptide derived from the pseudo-substrate regulatory domain of PKCa (residues 19-31) with a serine at position 25 replacing the wild-type alanine, it was used as protein kinase C substrate peptide for testing the protein kinase C activity.

Bisindolylmaleimide X hydrochloride (BIM-X hydrochloride) is a potent and selective protein kinase C (PKC) inhibitor.

HA-100 is an isoquinoline compound with an added piperazinylsulfonyl group that acts as an inhibitor of protein kinases (PKs), including PKA, PKC, and PKG (IC50s = 8, 12, and 4 ?M, respectively).

Decursinol angelate, a cytotoxic and protein kinase C (PKC) activating agent from the root of Angelica gigas, possesses anti-tumor and anti-inflammatory activities.
