Hirullin, originally isolated from the leech Hirudinaria manillensis, is a hirudin-based fibrinogen recognition peptide inhibitor, which binds efficiently to thrombin (IC₅₀= 4.2 µM, in bovine).
H-His-Asp-OH is a histidine derivative that has been shown to have antimicrobial activity. It binds to DNA and inhibits the polymerase chain reaction. The drug also has structural similarities with phosphatases, which may be due to its ability to bind to DNA in an activated form. H-His-Asp-OH is a potent inhibitor of bacterial growth and has been shown to inhibit the growth of Eukaryotes.
