Tetrahydroalstonine is an indole alkaloid extracted from the fruit of Rhazya stricta and is a selective α2-adrenoceptor antagonist. tetrahydroalstonine has shown antipsychotic activity in Rauwolfia tetraphylla.

SC-52012 is a novel and potent fibrinogen receptor antagonist, an RGD mimetic, which inhibits platelet aggregation.

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.
