PPACK (hydrochloride)

PPACK is a synthetic peptide derivative that irreversibly and specifically inhibits thrombin-mediated platelet activation by binding with high affinity to the active site of thrombin (Ki = 0.24 nM). It has been used as an anticoagulant (100 µM) and to study thrombin-mediated fibrin deposition, angiogenesis, and proinflammatory processes.Formal Name: D-phenylalanyl-N-[(1S)-4-[(aminoiminomethyl)amino]-1-(chloroacetyl)butyl]-L-prolinamide, dihydrochloride.
