Benzamidine is a reversible competitive inhibitor of trypsin, trypsin-like enzymes, and serine proteases. [4] It is often used as a ligand in protein crystallography to prevent proteases from degrading a protein of interest. The benzamidine moiety is also found in some pharmaceuticals, such as dabigatran.
Benzamide is an organic compound with the chemical formula of C 7 H 7 NO.It is the simplest amide derivative of benzoic acid.In powdered form, it appears as a white solid, while in crystalline form, it appears as colourless crystals. [5]
Acrosin active site residues, shown with competitive inhibitor benzamidine. An important structural element of β-acrosin is a highly charged patch (formed through both amino acids and post-translational modifications) on its surface region, that has been termed the "anion binding exosite."
Stock solutions are usually made up in anhydrous ethanol, isopropanol, or corn oil and diluted immediately before use. PMSF reacts specifically with the active site serine residue in serine hydrolases. It does not bind to any other serine residues in the protein.

Benzidine is prepared in a two step process from nitrobenzene.First, the nitrobenzene is converted to 1,2-diphenylhydrazine, usually using iron powder as the reducing agent.
A common route to primary amidines is the Pinner reaction.Reaction of the nitrile with alcohol in the presence of acid gives an iminoether.Treatment of the resulting compound with ammonia then completes the conversion to the amidine. [1]
Factor XI (FXI) is produced by the liver and circulates as a homo-dimer in its inactive form. [9] The plasma half-life of FXI is approximately 52 hours. The zymogen factor is activated into factor XIa by factor XIIa (FXIIa), thrombin, and FXIa itself; due to its activation by FXIIa, FXI is a member of the "contact pathway" (which includes HMWK, prekallikrein, factor XII, factor XI, and factor IX).
