Mechanism of Action

Targets/IC₅₀/Ki	PKCβ ^[1] (Cell-free assay) 6 nM PKCα ^[1] (Cell-free assay) 39 nM PKCγ ^[1] (Cell-free assay) 83 nM PKCε ^[1] (Cell-free assay) 110 nM
In vitro	Enzastaurin application results in a marked dose-dependent inhibition of growth in all MM cell lines investigated, including MM.1S, MM.1R, RPMI 8226 (RPMI), RPMI-Dox40 (Dox40), NCI-H929, KMS-11, OPM-2, and U266, with IC50 from 0.6-1.6 μM. This compound direct impacts human tumor cells, inducing apoptosis and suppressing proliferation in cultured tumor cells. It also suppresses the phosphorylation of GSK3β^ser9, ribosomal protein S6S240/244, and AKTThr308 while having no direct effect on VEGFR phosphorylation. ^[1] This chemical increases apoptosis in malignant lymphocytes of CTCL. When combined with GSK3 inhibitors, it demonstrated an enhancement of cytotoxicity levels. Treatment with a combination of this compound and the GSK3 inhibitor AR-A014418 led to increased levels of β-catenin total protein and β-catenin-mediated transcription. Blocking of β-catenin-mediated transcription or small hairpin RNA (shRNA) knockdown of β-catenin induced the same cytotoxic effects as that of it plus AR-A014418. Additionally, treatment with it and AR-A014418 decreased the mRNA levels and surface expression of CD44. ^[2]
Kinase Assay	Kinase inhibition assays
Kinase Assay	The inhibition of PKCβII, PKCα, PKCε, or PKCγ activity by enzastaurin is determined using a filter plate assay format measuring ³³P incorporation into myelin basic protein substrate. Reactions are done in 100 μL reaction volumes in 96-well polystyrene plates with final conditions as follows: 90 mM HEPES (pH 7.5), 0.001% Triton X-100, 4% DMSO, 5 mM MgCl₂, 100 μM CaCl₂, 0.1 mg/mL phosphatidylserine, 5 μg/mL diacetyl glyerol, 30 μM ATP, 0.005 μCi/μL ³³ATP, 0.25 mg/mL myelin basic protein, serial dilutions of this compound (1-2,000 nM), and recombinant human PKCβII, PKCα, PKCε, or PKCγ enzymes (390, 169, 719, or 128 pM, respectively). Reactions are started by addition of the enzyme and incubated at room temperature for 60 minutes. They are then quenched with 10% H₃PO₄, transferred to multiscreen anionic phosphocellulose 96-well filter plates, incubated for 30 to 90 minutes, filtered and washed with 4 volumes of 0.5% H₃PO₄ on a vacuum manifold. Scintillation cocktail is added and plates are read on a Microbeta scintillation counter. IC50 values are determined by fitting a three-variable logistic equation to the 10-point dose-response data using ActivityBase 4.0.
In vivo	Treatment of xenografts with Enzastaurin and radiation produced greater reductions in density of microvessels than either treatment alone. The decrease in microvessel density corresponded to delayed tumor growth. ^[3]
