Description

(R)-Flurbiprofen is a COX-inactive enantiomer of the racemic non-selective COX inhibitor flurbiprofen that has diverse biological activities. It inhibits γ-secretase activity in vitro and, in vivo, it reduces formation of amyloid-β peptide 1-42 (Aβ42) and improves axonal transport in young Aβ-plaque free mice but not old mice with existing Aβ plaques in the Tg2576 transgenic model of Alzheimer''s disease. (R)-Flurbiprofen inhibits NF-kB activation and DNA binding as well as AP-1 DNA binding in RAW 264.7 macrophages and reduces paw edema in a rat model of zymosan-induced inflammation via COX-independent inhibition of NF-κB and AP-1 activation when administered at doses of 1, 3, and 9 mg/kg. It also suppresses prostate tumor cell growth in vitro by inducing p75NTR protein expression and reduces tumor growth and metastasis in multiple mouse models of intestinal neoplasia.

Uses

(R)-2-Flurbiprofen is the R-isomer of Flurbiprofen (F598700), an anti-inflammatory used as an analgesic.

Biochem/physiol Actions

gamma secretase inhibitor; amyloid Abeta 42 lowering agent

Check Digit Verification of cas no

The CAS Registry Mumber 51543-40-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,5,4 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 51543-40:
(7*5)+(6*1)+(5*5)+(4*4)+(3*3)+(2*4)+(1*0)=99
99 % 10 = 9
So 51543-40-9 is a valid CAS Registry Number.

An efficient method for the synthesis of (S)-flurbiprofen by 1,2-rearrangement of the aryl group

Chen, Hua,Dai, Yuhao,Liu, Yu,Luo, Kaihong,Zhang, Yi

, (2022/03/15)

(S)-Flurbiprofen (1) is a nonsteroidal anti-inflammatory drug (NSAID) used to relieve pain and inflammation associated with osteoarthritis. Herein a new and practical method for the preparation of 1 from 4-bromo-2-fluorobiphenyl (2) is reported, which achieves a good overall yield (20%) and high enantioselectivity (96%). This method avoids the use of expensive catalysts and affords the possibility of large-scale manufacturing with simple operations.

Enantioselective Synthesis of Chiral Carboxylic Acids from Alkynes and Formic Acid by Nickel-Catalyzed Cascade Reactions: Facile Synthesis of Profens

Fu, Kaiyue,Ma, Yu,Sun, Yaxin,Tang, Bo,Yang, Guang,Yang, Peng,Yue, Jieyu,Zhang, Li,Zhou, Jianrong Steve

supporting information, (2021/11/22)

We report a stereoselective conversion of terminal alkynes to α-chiral carboxylic acids using a nickel-catalyzed domino hydrocarboxylation-transfer hydrogenation reaction. A simple nickel/BenzP* catalyst displayed high activity in both steps of regioselective hydrocarboxylation of alkynes and subsequent asymmetric transfer hydrogenation. The reaction was successfully applied in enantioselective preparation of three nonsteroidal anti-inflammatory profens (>90 % ees) and the chiral fragment of AZD2716.

Palladium-Catalyzed Asymmetric Markovnikov Hydroxycarbonylation and Hydroalkoxycarbonylation of Vinyl Arenes: Synthesis of 2-Arylpropanoic Acids

Guan, Zheng-Hui,Ren, Zhi-Hui,Wang, Yuan,Yang, Hui-Yi,Yao, Ya-Hong,Zou, Xian-Jin

supporting information, p. 23117 - 23122 (2021/09/18)

Asymmetric hydroxycarbonylation is one of the most fundamental yet challenging methods for the synthesis of carboxylic acids. Herein, we reported the development of a palladium-catalyzed highly enantioselective Markovnikov hydroxycarbonylation of vinyl arenes with CO and water. A monodentate phosphoramidite ligand L6 plays vital role in the reaction. The reaction tolerates a range of functional groups, and provides a facile and atom-economical approach to an array of 2-arylpropanoic acids including several commonly used non-steroidal anti-inflammatory drugs. The catalytic system has also enabled an asymmetric Markovnikov hydroalkoxycarbonylation of vinyl arenes with alcohols to afford 2-arylpropanates. Mechanistic investigations suggested that the hydropalladation is irreversible and is the regio- and enantiodetermining step, while hydrolysis/alcoholysis is probably the rate-limiting step.
