General description
Antipain is known for regulating the number of chromosomal aberrations caused by the S-phase-dependent alkylating agent N-methyl-N′-nitro-N-nitrosoguanidine. It can also diminish the nuclear binding of the estrogen-receptor complex in MCF-7 breast tumor cells.
Application
Antipain has been used in microfluidic chip assay.
Biochem/physiol Actions
Inhibitor Type: Protease Inhibitors
Quality
pH 1% aqueous solution: 5.2
Physical form
Lyophilized no preservatives.
Properties: Soluble in H2O, methanol and DMSO (Stock solution: 10 mM). Stable at -20° C.
Mechanism of action: Formation of a hemicetal adduct between the aldehyde group of the inhibitor and the active serine of the proteinase.
Inhibition spectrum: Inhibits papain, trypsin and plasmin to a lesser extent. More specific for papain and trypsin than leupeptin. The inhibitory potency of antipain is 100-fold higher than that of elastatinal.
Pale yellow powder; material is isolated from cultured media of microorganisms. As with many of these compounds, they are too inherently unstable to allow for high standards of purity. The homogeneity of these compounds cannot be guaranteed except for their specific inhibitory activities.
