Sincalide ammonium (Cholecystokinin octapeptide ammonium) is a rapid-acting amino acid polypeptide hormone analogue of cholecystokinin (CCK) for intravenous use in postevacuation cholecystography.

Activator of protein kinase C; attached to cell permeabilization Antennapedia domain vector peptide. Consists of peptide derived from the C2 domain of PKC β linked by a disulfide 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 activator peptide. Once inside the cell, the disulfide bonds are subjected to reduction in the cytoplasm leading to release of the activator peptide.

Celosin L is a triterpenoid saponin with hepaprotective activity. Celosin L exhibits protective effects against APAP-induced hepatotoxicity in HepG2 cells.
