PKCε Inhibitor Peptide acetate is a selective PKCε inhibitor containing the site for its specific receptor for activated C kinase (RACK). PKCε Inhibitor Peptide acetate inhibits the translocation of PKCε, but not α-, β-, and δPKC.

PKCε Inhibitor Peptide acetate(1 µM; 24 hours) significantly inhibits Oleic acid-induced connexin 43 Ser368 phosphorylation and prevents Oleic acid-induced gap junction disassembly in cardiomyocytes[1].

In C57BL/6J mice transplanted the hearts of FVB mice, PKCε Inhibitor Peptide acetate (20 mg/kg/day; osmotic pumps s.c.) significantly improved the beating score throughout the treatment. PKCε Inhibitor Peptide acetate treatment almost abolished the rise in pro-fibrotic cytokine, TGF-β, and monocyte recruiting chemokine MCP-1 levels. PKCε Inhibitor Peptide acetate reduced the infiltration of macrophages and T cells into the cardiac grafts and decreased parenchymal fibrosis[2].
