Pefabloc® TH, Inhibitor for Thrombin/NAPAP
Description:
The benzamidine moiety is a key structure for the development of inhibitors of trypsin-like enzymes. It mimics the protonated side-chain of the basic amino acids Arg and Lys which is hydrolysed by these enzymes. Pefabloc®TH (NAPAP) is one of the most potent and selective competitive inhibitors of thrombin.
Application:
Pefabloc®TH can be used in diagnostic systems, analytical applications, research and industrial purification processes to exclude undesired thrombin activity. It can also be used as a potent anticoagulant in in vitro test systems.
Formula: C27H31O4N5S · AcOH
MW: 581.7
Chem. name:
Nα-(2-Naphthylsulfonylglycyl)-4-amidino-(D,L)-phenylalanine piperidide acetate (NAPAP)
