Descrição geral

Pefabloc^® SC is a potent, nontoxic and relatively easy to use, irreversible serine proteinase inhibitor. It is reported to efficiently inhibit the platelet activating factor (PAF)-degrading acetylhydrolase (acetylhydrolase) in both humans and rats.[1]

Pefabloc^® SC is a trypsin inhibitor, which can be used in the synthesis of its arginine-like analogue, 4-(2-guanidinoethyl)benzenesulfonyl fluoride.[2]

Aplicação

Pefabloc^® SC may be used as an analytical standard in determining the native oligomeric state and substrate specificity of rat NTPDase1 and NTPDase2 after heterologous expression in Xenopus oocytes.[3] It may also be used as an esterase inhibitor, which is added to the whole blood to improve the stability of ciclesonide for the determination of ciclesonide (CIC) and its active metabolite, desisobutyryl-ciclesonide (des-CIC), in human plasma using liquid chromatography-atmospheric pressure chemical ionization-tandem mass spectrometric (LC-APCI-MS/MS) method.[4]

Recommended concentrations for use are 0.1-1 mM.

Ações bioquímicas/fisiológicas

4-(2-Aminoethyl)benzenesulfonyl fluoride hydrochloride (AEBSF) is an irreversible serine protease inhibitor. Inhibition constants are similar to those of phenylmethanesulfonyl fluoride (PMSF) and diisopropylfluorophosphate (DFP). AEBSF has been shown to inhibit trypsin, chymotrypsin, plasmin kallikrein, and thrombin. As an alternative to PMSF and DFP, AEBSF offers lower toxicity, improved solubility in water, and improved stability in aqueous solutions. AEBSF can be used in cell culture in concentrations of up to 0.25 mM.

Outras notas

Potent and irreversible inhibitor of serine proteases; in contrast to PMSF, it is water soluble and non-toxic[5][6]; Unaffected by albumin[7]
