• 개요

  Ibuprofen is a non-steroidal anti-inflammatory drug with diverse biochemical actions, most notably inhibiting COX-1 and COX-2 (IC₅₀s = 2.6 and 1.53 μM, respectively). It is commonly synthesized as a racemic mixture of (S) and (R) isomers (Item No. item 70280). (R)-Ibuprofen is an enantiomer that is generally not considered a COX inhibitor and is instead thought to be involved in pathways of lipid metabolism as it is incorporated into triglycerides along with fatty acids. The (R) enantiomer can, however, inhibit NF-κB activation (IC₅₀ = 121.8 μM) in response to T-cell stimulation as well as block superoxide formation, β-glucuronidase release, and LTB₄ generation by stimulated neutrophils (IC₅₀ values range from 40-100 μM). 50-60% of (R)-ibuprofen is inverted to (S)-ibuprofen in humans after oral administration.

  White Crystalline Solid

• Purification Methods

  Crystallise the (+) and (-) acids from EtOH or aqueous EtOH. The racemate which crystallises from pet ether with m 75-77o is sparingly soluble in H2O and has IR (film) 1705 (C=O), 2300—3700 (OH broad)cm-1. It is used as a non-steroidal anti-inflammatory.
