Descrizione

Descrizione generale

Antipain is a protease inhibitor isolated from actinomycetes. It inhibits thrombokinase and blood coagulation.

Applicazioni

Concentrations for 50% inhibition (μg/ml):
papain, 0.16
trypsin, 0.26
cathepsin A, 1.19
cathepsin B, 0.59
cathepsin D, 125
plasmin, >93
chymotrypsin and pepsin, >250
It also has been reported to inhibit calpain I, (porcine) with K_i = 1.4 μM

Azioni biochim/fisiol

Reversible inhibitor of serine/cysteine proteases and some trypsin-like serine proteases. Its action resembles leupeptin; however, its plasmin inhibition is less and its cathepsin A inhibition is more than that observed with leupeptin. Chronic administration of antipain can reduce the frequency of chemically induced transformation in BALB/c-/3T3 cells.

Formula: C₂₇H₄₄N₁₀O₆ x 2 HCl

Nota sulla preparazione

Working concentration: 50 μg/ml

Working solution: Soluble in water, methanol, or DMSO to 20 mg/ml. Sparingly soluble in ethanol, propanol, or butanol. Insoluble in benzene, chloroform (CHCl₃), hexane, or petroleum and ethyl ethers.
Storage conditions (working solution): -15 to -25 °C
Dilute solutions should be stored frozen in aliquots at -15 to -25 °C. Growth of microorganisms and repeated freezing should be avoided. Stable for approximately one month.

Solubility testing at 50 mg/ml in water yields a clear to slightly hazy yellow solution. It is reportedly soluble in methanol, water, and DMSO; less soluble in ethanol, butanol, and propanol; insoluble in benzene, hexane, and chloroform.⁸ A stock solution in water or buffer is stable for about a month at -20 °C.

Dilute solutions should be stored on ice and kept for only a day because of the terminal aldehyde, which is subject to oxidation and racemization.

Ricostituzione

Soluble in water, methanol, or DMSO to 20 mg/ml. Sparingly soluble in ethanol, propanol, or butanol. Insoluble in benzene, chloroform (CHCl₃), hexane, or petroleum and ethyl ethers. Dilute solutions should be stored frozen in aliquots at -15 to -25 °C. Stable for approximately one month.
CAUTION: DMSO (Dimethyl sulfoxide) will permeate the skin, carrying solubilized protease inhibitors. Always wear appropriate protection for eyes, skin, etc.
