SINOACUTINE is a natural product isolated from Stephania epigaea Lo.Sinoacutine has protective effects against hydrogen peroxide-induced cell injury.

Inhibitor of protein kinase C (PKC) ζ; attached to cell permeabilisation Antennapedia domain vector peptide. Consists of amino acids 113 - 129 of PKC ζ pseudosubstrate domain linked by a disulphide bridge to the Antennapedia domain vector peptide. The Antennapedia peptide is actively taken up by intact cells, at 4 or 37°C, ensuring rapid and effective uptake of the inhibitor peptide. Once inside the cell, the disulphide bonds are subjected to reduction in the cytoplasm leading to release of the inhibitor peptide. Induces mast cell degranulation by a PKC ζ-independent pathway.

Sapienic acid sodium is a fatty acid commonly. It has variable antimicrobial activities against Gram-positive and Gram-negative bacteria found on the skin and in the oral cavity.
