Biological Activity

Description Suprofen is a dual COX-1/COX-2 inhibitor, used as a non-steroidal anti-inflammatory analgesic and antipyretic.
COX-1 [1] COX-2 [1]
In vitro

Suprofen inactivates the diclofenac-4-hydroxylase activity of baculovirus-expressed P450 2C9 in a time- and concentration-dependent manner, which is consistent with mechanism-based inactivation. [1] Suprofen is a known generator of singlet oxygen whose participation in the reaction is supported by the effects of quenchers and scavengers. Suprofen photosensitizes the production of alkali-labile cleavage sites in DNA much more efficiently than direct strand breaks. [2] Suprofen sensitizes photo-oxidation of cholesterol, producing 7 alpha- and 7 beta-hydroperoxides but not 5 alpha-hydroperoxide of cholesterol. Suprofen-sensitized photo-oxidation of membrane lipids of liposomes increases leakage of trapped glucose, suggesting photosensitized destabilization of the membrane structure. [3] Suprofen incorporation in the phosphatidylcholine (PC) evaporation vesicles (REV) membrane leads to approximately 5% increase in the encapsulation efficiency (34%) in comparison to standard REV (29%). [4]

In vivo Suprofen combined with PGF2 alpha blocks induction of uterine contractions, suggesting the possibility that Suprofen also antagonizes PGF2 alpha receptor binding. [5] Suprofen are effective at preventing BAB disruption after paracentesis in dogs, indicating their potential usefulness for treatment of prostaglandin-mediated ocular disease. [6] Suprofen (3.7 mg/kg, i.v.) induces a marked decrease in the firing evoked in arthritic rats by ankle mobilization. [7]

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.
