Biological Activity

Description Fudosteine is a cysteine derivative and a MUC5AC mucin hypersecretion inhibitor, used as a muco-active agent with indications for chronic respiratory diseases.
In vitro
In vitro Fudosteine (FDS), a unique mucolytic antioxidant, shows a stronger scavenging effect of Peroxynitrite than N-acetyl-cysteine on DCDHF oxidation in vitro and in sputum macrophages, and also on Peroxynitrite-induced BSA nitration. Fudosteine (0.1 mM) reduces Peroxynitrite-enhanced interleukin (IL)-1beta-induced IL-8 release and restores corticosteroid sensitivity defected by Peroxynitrite more potently than those induced by H(2)O(2) in A549 airway epithelial cells. [1] Fudosteine significantly inhibits increases in GRO/CINC-1 at 10-100 mg/kg, and neutrophils and goblet cells at 30 and 100 mg/kg. Fudosteine inhibits goblet cell hyperplasia by inhibiting GRO/CINC-1 production and/or neutrophil migration. [2] Fudosteine treatment reduces the expression levels of p-p38 MAPK and p-ERK in vivo and of p-ERK in vitro. Fudosteine inhibits MUC5AC mucin hypersecretion by reducing MUC5AC gene expression and the effects of fudosteine are associated with the inhibition of extracellular signal-related kinase and p38 mitogen-activated protein kinase in vivo and extracellular signal-related kinase in vitro. [3] Fudosteine significantly suppresses blood flow of tracheal microvasculature increased by SO(2) exposure. Fudosteine scavenges superoxide anion generated from rat neutrophils, and enzymatically generated from xanthine oxidase-acetaldehyde reaction. [4]
In Vivo
In vivo Fudosteine (500 mg/kg, p.o.) significantly increases the amount of dye excreted into the respiratory tract. Fudosteine increases chloride ion concentration in broncho-alveolar lavage of rats. [5]

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
