General description

A potent, cell-permeable, reversible, ATP-competitive, and selective protein kinase C inhibitor (IC50 = 15 nM for rat brain PKC). Exhibits some degree of isozyme specificity (IC50 = 8 nM for PKCα, 8 nM for PKCβI, 14 nM for PKCβII, 13 nM for PKCγ, and 39 nM for PKCε). Shows slight selectivity for the conventional PKC isozymes PKCα, PKCβ, and PKCγ over the Ca2+-independent PKC isozyme PKCε. Upregulates CD11a expression and enhances mesenchymal stromal cell adhesion under flow.

Notch signaling dictates cell fate decisions in mammalian cells including megakaryocytes. Existence of functional Notch signaling in enucleate platelets remains elusive. Transcripts/peptides of Notch1 and Delta-like ligand (DLL)-4 were detected in platelets isolated from human blood by RT-qPCR, Western analysis
