(S)-Flurbiprofen Chemical Properties,Usage,Production
Description
Marketed by Taisho Pharmaceutical Holdings Co., Ltd., and Teijin Pharma Ltd., the (S)-enantiomer of flurbiprofen (named Esflurbiprofen) was approved as a new drug by the PMDA of Japan in 2015. (S)- Flurbiprofen, a cyclooxygenase (COX)-inhibiting nonsteroidal anti-inflammatory (NSAID) drug, is formulated with mentha oil and administered by way of a patch as a treatment for osteoarthritis in the current invention. Interestingly, the (R)- enantiomer is responsible for minimal COX inhibition but has been implicated as a possible treatment for a variety of other diseases. Synthetic approaches to racemic flurbiprofen have been reported in the chemical literature as early as the 1960s, and the mixture was approved as a drug in the United States by the FDA in 1988, marketed by Pharmacia and Upjohn. Toward this end, the current patent estate defines the utility of the active S-enantiomer, and synthetic approaches therein apply to this enantiomer only.
Description
(S)-Flurbiprofen is the COX-active enantiomer of the non-selective COX inhibitor flurbiprofen with IC50 values of 0.48 and 0.47 μM for COX-1 and COX-2, respectively, in guinea pig whole blood. It inhibits the release of 6-keto prostaglandin F1α (6-keto-PGF1α; ) and thromboxane B2 (TXB2; ) from rat whole blood, gastric mucosa, lung, and jejunal tissue ex vivo in a dose-dependent manner. (S)-Flurbiprofen (1 nM) inhibits basal and bradykinin-, serotonin-, and histamine-stimulated prostaglandin E2 (PGE2) release from isolated skin flaps of rat lower hind paws. It also inhibits release of the neuroinflammatory marker calcitonin gene-related peptide (CGRP; Item Nos. 24405 | 24725 | 24728) when used at a concentration of 1 μM. In vivo, (S)-flurbiprofen reduces the number of flinches per minute in the formalin test in rats, indicating antinociceptive activity.
Uses
(S)-Flurbiprofen is the S-isomer of Flurbiprofen (F598700), an anti-inflammatory used as an analgesic.
Definition
ChEBI: (S)-flurbiprofen is a flurbiprofen. It is an enantiomer of a (R)-flurbiprofen.
Synthesis
The synthesis began with conversion of commercially available aniline 168 to racemic flurbiprofen (169) through a Sandmeyer reaction and subsequent phenyl group introduction through the use of sodium tetraphenylborate. A chiral resolution was then performed on the resulting stereogenic acid on multikilogram scale by treatment with (S)- 1-phenylethylamine in MeOH/toluene, which gave various yields of salt 170 as reported by the authors. Acidification with aqueous HCl delivered (S)-flurbiprofen (XXI). Importantly, with respect to green chemistry considerations, the (R)- enantiomer could be recycled by racemizing the undesired (R)- enantiomer 171 in refluxing methanolic sulfuric acid, improving the overall atom economy of the process and significantly reducing waste.
in vitro
it was found that the ic50 value of (s)-flurbiprofen was about 0.5 μm for both cox-1 and cox-2 in guinea pig whole blood [1].
in vivo
the efficacy of multiple applications of s(+)-flurbiprofen plaster (sfpp) was evaluated for the alleviation of inflammatory pain and edema in rat adjuvant-induced arthritis model. multiple applications of sfpp could exert a significant analgesic effect from the first day of application as compared to the other nsaid drugs. in terms of paw edema, sfpp could decrease edema from the second day after application. moreover, multiple applications of sfpp were found to be superior to those of other nsaid drugs in terms of the analgesic effect [2].
