KYP-2047 is a very potent, selective Prolyl oligopeptidase (POP) inhibitor.In cell lines, oxidative stress induced a robust aggregation of α-synuclein,and low concentrations of KYP-2047 significantly reduced the number of cells with α-synuclein inclusions while abolishing the colocalization of α-synuclein and PREP.

Fibrinogen-Binding Peptide (designed by anticomplementarity hypothesis) is a presumptive peptide mimic of the vitronectin binding site on the fibrinogen receptor. Fibrinogen, a soluble plasma protein, is a cofactor in platelet activation. It is converted to fibrin in a reaction catalyzed by thrombin.

RLX-33 is a potent and selective antagonist of relaxin family peptide 3 (RXFP3) that crosses the blood-brain barrier and also blocks relaxin 3-induced ERK1/2 phosphorylation.
