Product Introduction

Bioactivity

Description	FK-448 Free base is a potent and specific chymotrypsin inhibitor, with an IC50 of 720 nM.
Targets&IC50	Chymotrypsin:720 nM
In vitro	FK-448 Free base slightly inhibits esterolysis of Trypsin and Thrombin, with IC50s of 780 and 35 μM, respectively, but shows no effects on esterolysis of plasmin, plasma kallikrein or pancreas kallikrein, with IC50s of all >1 mM. FK-448 moderately inhibits hydrolytic activities of cathepsin G with an IC50 of 15 μM. FK-448 Free base is an effective and specific inhibitor of chymotrypsin, with an IC50 of 720 nM.
In vivo	FK-448, administered orally (p.o.) at a dose of 20 mg/kg, not only reduces the blood glucose level but also elevates the plasma Insulin Release Inhibitor (IRI) level in dogs. Meanwhile, when delivered intraperitoneally (i.p.) at the same dosage, FK-448 leads to a decreased blood glucose level and prevents the breakdown of insulin by pancreatic enzymes in rats.

Please enter your animal experiment information in the following box and click Calculate to obtain the mother liquor preparation method and in vivo formula preparation method:

For example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . TargetMol | Animal experiments

A total of 10 animals were administered, and the formula you used is 5% TargetMol | reagent

DMSO+30% PEG300+5% Tween 80+60% ddH2O. So your working solution concentration is 2 mg/mL。

Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSO TargetMol | reagent

(mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.

Preparation method for in vivo formula: Take 50 μL DMSO TargetMol | reagent

main solution, add 300 μLPEG300 TargetMol | reagent

mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2O TargetMol | reagent

mix well and clarify
