JW 642 (1416133-89-5) Usage

In laboratory procedures,for long term storage,we suggest that JW 642be stored assupplied at -20℃. It should be stable for at least one year.
JW 642 is supplied as a solution in methyl acetate. To change the solvent,simply evaporate the methyl acetate under a gentle stream of nitrogen and immediately addthe solvent of the choice. Solvents such asethanol,DMSO,and dimethyl formamide purged with an inert gas can be used. The solubility of JW 642 in these solvents isapproximately 13,5,and 11mg/ml,respectively.
JW 642 is sparingly soluble in aqueous buffers. For maximum solubility in aqueousbuffers,the ethanolic solution of JW 642should be diluted with the aqueous buffer ofchoice. JW 642 has a solubility of approximately 0.3 mg/ml in a 1:2 solution of ethanol:PBS(pH 7.2) using this method. We do not recommend storing the aqueous solution for more than one day.


What is the dosage of JW 642

DMSO to 100 mM
Ethanol to 100 mM
Stability and Solubility Advice: Some solutions can be difficult to obtain and can beencouraged by rapid stirring, sonication or gentle warming (in a 45-60°C water bath). Information concerning product stability, particularly in solution, has rarely been reported and in most cases we can only offer a general guide. Our standard recommendations are: SOLIDS: Provided storage is as stated on the product label and the vial is kept tightly sealed, the product can be stored for up to 6 months from date of receipt. SOLUTIONS: We recommend that stock solutions, once prepared, are stored aliquoted in tightly sealed vialsat -20°C or below and used within 1 month.Wherever possible solutions should be made up and used on the same day.


How JW 642 works

JW 642 is a potent and selective monoacylglycerol lipase (MAGL) inhibitor (IC = 3.7 nM). Displays >1000-fold selectivity for MAGL over fatty acid amidehydrolase (IC = 20.6 μM). Monoacylglycerol lipase (MAGL) isa serine hydrolase responsible for the hydrolysis of 2-AG to arachidonic acid and glycerol, thus terminating its biological function. Toxicological Effects may be caused like below: Methyl Acetate – Toxicity Data: Oral LD50 (rat): >5,000 mg/kg; Oral LD50 (rabbit): 3,705 mg/kg; Skin LD50(rabbit): >5,000 mg/kg; Inhalation TCLO (human): 15,000 mg/m3; Methyl Acetate – Irritation Data: Skin (rabbit): 500 mg (24h) mild; Eyes (rabbit):100 mg (24h)moderate.
