BAM-12P, an endogenous opioid peptide, is a novel pro-Met-enkephalin. BAM-12P can activate human κ-opioid receptor (hKOR) with an EC50 of 101 nM and a pEC50 of 6.99. BAM-12P is a ligand for CXCR7 with an EC50 of 175 nM.

SP-13786 is an inhibitor of fibroblast activation protein (FAP) (IC50 : 3.2 nM); also inhibits prolyl oligopeptidase (PREP) ( IC50 : 1.8 μM).

Isokaempferide shows hepatoprotective, antiproliferative, and anti-inflammatory effects, the anti-inflammatory effects can be explained, at least in part, by reducing neutrophil degranulation, myeloperoxidase activity, mediators as well as TNF-alpha secretion.
