Biological Activity

Description Sotrastaurin (AEB071) is a potent and selective pan-PKC inhibitor, mostly for PKCθ with Ki of 0.22 nM in a cell-free assay; inactive to PKCζ. Phase 2.
Targets
PKCθ [1]
(Cell-free assay)		 PKCβ1 [1]
(Cell-free assay)		 PKCα [1]
(Cell-free assay)		 PKCη [1]
(Cell-free assay)		 PKCδ [1]

In vitro

Sotrastaurin (< 10μM) treatment effectively abrogated at low nanomolar concentration markers of early T-cell activation, such as interleukin-2 secretion and CD25 expression, in primary human and mouse T cells. Sotrastaurin (200 nM) inhibits the CD3/CD28 antibody- and alloantigen-induced T-cell proliferation responses in the absence of nonspecific antiproliferative effects. Sotrastaurin (<3 μM) markedly inhibits lymphocyte function-associated antigen-1-mediated T-cell adhesion. [1]

Sotrastaurin(< 20 μM) selectively impair the proliferation of CD79 mutant ABC DLBCL cell lines, correlating with decreased NF-κB signaling avctivity. AEB071 at concentration of 5 μM induces G1 arrest and/or cell death in CD79 mutant cells. [2]
In vivo

Sotrastaurin (80 mg/kg) results in significant inhibition of in vivo tumor growth in a subcutaneous TMD8 xenograft model in SCID. [2]

Sotrastaurin orally administrated at 10 mg/kg and 30 mg/kg b.i.d. show a dose-dependent immunosuppressive effect leading to pronounced prolongation of heart allograft survival in rats. [3]
Features Unlike former PKC inhibitors, Sotrastaurin does not enhance apoptosis of murine T-cell blasts in a model of activation-induced cell death.

Protocol (from reference)

Kinase Assay:

[1]
  • Protein Kinase Assays

    Classical and novel PKC isotypes are assayed by scintillation proximity assay technology. In brief, the assay is performed in 20 mM Tris-HCl buffer, pH 7.4, and 0.1% bovine serum albumin by incubating 1.5 μM of the peptide substrate with 10 μM [33P]ATP, 10 mM Mg (NO3)2, 0.2 mM CaCl2, and PKC at a protein concentration varying from 25 to 400 ng/mL, and lipid vesicles containing 30 mol% phosphatidylserine, 5 mol% diacylglycerol (DAG), and 65 mol% phosphatidylcholine at a final lipid concentration of 0.5 μM. Incubation is performed for 60 min at room temperature. The reaction is stopped by adding 50 μl of a mixture containing 100 mM EDTA, 200 μM ATP, 0.1% Triton X-100, and 0.375 μg/well streptavidin-coated scintillation proximity assay beads in PBS without Ca2+ and Mg2+. Incorporated radioactivity is measured in a MicroBetaTrilux counter for 1 min.
