Background

FK 3311, a cell-permeable and orally available sulfonanilide, is a highly selective inhibitor of cyclooxygenase (COX)-2 with IC 50 value of 1.6 μM.
Cyclooxygenase-2 (COX-2) is a membrane bound enzyme that transfers the electrons from cytochrome c to the catalytic subunit 1. The expression of COX-2 is tightly regulated and induced by different mediators such as cytokine, growth factor, and endotoxin.
FK3311 was shown to selectively inhibit consititutive and inducible COX-2 activity in human platelets and mononuclear cells [1].
The component has also been used extensively in various animal models to study the role of COX-2. In ischemia-reperfusion rat model, administration of FK 3311 via the penile vein can significantly reduce the serum levels of aspartate aminotransferase (AST), lactate dehydrogenase (LDH), alanine aminotransferase (ALT) and thromboxane (Tx) B2.  However, FK 3311 treatment did not reduce the 6-keto-PG F1a levels in these rats[2]. In addition, liver tissue blood flow was remarkably better in the FK3311 treated rat compared with their control group. Histological examination of the livers revealed that FK3311 treatment reduced the hepatic tissue damage and improved the liver graft function [3]. In the canine lung transplantation model, treatment of FK3311 reduced lung damage, neutrophil infiltration into lung, technetium-99m-albumin accumulation and thromboxane B2 level. The lung with FK3311 treatment had better pulmonary gas exchange and hemodynamics [4].

Calculation results:

Working concentration: mg/ml;

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.
3. All of the above co-solvents are available for purchase on the GlpBio website.
