Lupinine is a bitter tasting quinolizidine alkaloid present in Lupinus species of the Family Fabaceae. It has been shown to lower the locomotion excitation brought on by ethanol anesthesia in mice. Lupinine has also shown some ability to inhibit human and rabbit cholinesterases.

PPACK is a synthetic peptide that irreversibly inhibits thrombin-mediated platelet activation by binding to the active site of thrombin with a Ki = 0.24 nM. PPACK competes with alpha-thrombin at the high-affinity site and is an antagonist of alpha-thrombin induced activation. PPACK is used as a tool for assessment of Platelet function.

N-(Fluorenyl-9-methoxycarbonyl)leucine (NPC 15199) is an organic compound that demonstrates antiinflammatory effects. NPC 15199 and other N-(9-fluorenylmethoxycarbonyl)-protected amino acids are demonstrated to block recruitment of neutrophils into inflammatory lesions and to inhibit T-cell activation in vitro, and are classified as leumedins. N-(Fluorenyl-9-methoxycarbonyl)leucine is described to act as a chemically distinct ligand and modulator of PPARγ (peroxisome proliferator-activated receptor γ). N-(Fluorenyl-9-methoxycarbonyl)leucine is demonstrated to increase intracellular Ca2+ and to mobilize Ca2+ stores in human bladder female transitional cancer (BFTC) cells.
