Biological Activity

Description Sivelestat sodium tetrahydrate (ONO5046-Na, EI546, LY544349) is a competitive inhibitor of human neutrophil elastase, also inhibits leukocyte elastase obtained from rabbit, rat, hamster and mouse.
Targets
neutrophil elastase [1]
In vitro
In vitro Sivelestat suppresses both adhesion and transmigration of neutrophils to the endothelium[2].
Cell Research Cell lines human umbilical vein endothelial cell (HUVEC)
Concentrations 1, 10, and 50 μg/mL
Incubation Time 1 h
Method

HUVEC are grown to confluence on fibronectin (25 μg/mL) coated Falcon cell culture inserts. Neutrophils stimulated by PAF (0.1 mM) are added to the HUVEC monolayers (upper chamber). The upper chamber is exposed to 2 mL of HUMEDIA and rehydrated at 37 ℃ for 1 h in the absence or the presence (50 μg/mL) of sivelestat. Subsequently, the upper chamber is removed and the fluid in the lower chamber is collected.

In Vivo
In vivo Intraoperative administration of sivelestat effectively reduced neutrophil induction and activation in the lung and improved oxygenation after cardiopulmonary bypass in a piglet model[1].By inhibiting neutrophil elastase, sivelestat has a direct action to the accumulated and activated leucocytes, offering efficient protection against the production of oxygen radicals and cytokines[3].
Animal Research Animal Models Neonatal piglets
Dosages 2 mg/kg/h
Administration Intraoperative administration

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.
