Timosaponin A1 is a coprostane type steroidal saponin isolated from Rhizoma Anemarrhenae.

Suriclone (RP 31264) is a selective cyclic pyrrolidone analog with sedative and anxiolytic activity, but not significant sedative effects.Suriclone shows its effects by modulating GABA-A receptors.

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.
