Biological Activity

Description FSLLRY-NH2 TFA (FSY-NH2) is a selective protease-activated receptor 2 (PAR2) inhibitor with an ic50 of 50 µM in PAR2-KNRK cells.
Targets
PAR2 [1]
(in PAR2-KNRK cells)
50 µM
In vitro
In vitro

FSLLRY-NH2 blocks the ability of trypsin to activate PAR(2) either in PAR(2)-expressing Kirsten virus-transformed kidney (KNRK) cell lines or in a rat aorta ring preparation. The mechanism of this activity does not involve a simple inhibition of trypsin proteolytic activity, but possibly by interacting with a tethered ligand receptor-docking site.<sup><a class="sref"href="#s_ref">[1]</a></sup>
Cell Research Cell lines Kirsten virus-transformed kidney (KNRK) cells
Concentrations 200 μM
Incubation Time 1 h
Method

KNRK cells are incubated with 10 nM trypsin  at 37°C for 10 to 60 min in the presence or absence of 200 μM FSLLRY-NH2. The absorbance of the released resorufin, reflecting proteolytic activity, is measured using a Beckman DU 640B Spectrophotometer at 574 nm for assay of proteolytic activity of trypsin.
In Vivo
In vivo

Treatment with FSLLRY-NH2 significantly improves neurological outcome and reduces the number of degenerating hippocampal neurons after ACA (asphyxial CA).<sup><a class="sref"href="#s_ref">[2]</a></sup>

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.
