(S)-(+)-Ketoprofen Usage And Synthesis

Chemical Properties

White Solid

Uses

COX inhibitor

Uses

Anti-inflammatory; analgesic

Definition

ChEBI: A monocarboxylic acid that is (S)-hydratropic acid substituted at position 3 on the phenyl ring by a benzoyl group. A cyclooxygenase inhibitor, it is used to relieve short-term pain, such as muscular pain, dental pain and dysmenorrhoea.

Biological Activity

(s)-ketoprofen, a dual cox1/2 inhibitor, can be used as a nonsteroidal anti-inflammatory drug to treat arthritis-related inflammatory pains. ketoprofen is photolabile and undergoes degradation when irradiated by sunlight to induce various skin diseases [1].

in vitro

the combination of uvb irradiation with ketoprofen dose-dependently induced the cytotoxicity and suppressed dna synthesis in hacat cells. uvb-irradiated kp inhibited the cell growth and induced g2/m cell cycle arrest by regulating the levels of cdc2, cyclin b1, chk1, tyr15-phosphorylated cdc2 and p21. the dapi staining results has revealed that kp accentuated the apoptotic response to uvb radiation in hacat cells [1].

in vivo

in a placebo-controlled, double-blind study in the rhesus monkeys macaca mulatta with periodontal disease, administeration of kp at 1% level in suitable topical vehicles to the gingiva once daily at a standard dose of 1.8 ml per monkey for 6 months effectively inhibited gcf-ltb4 and gcf-pge2 and positively altered alveolar bone activity [2]. ketoprofen at a dose of 3.63 mg/kg bwt (phenylbutazone equimolar dose) showed significant analgesic effects and reduced hoof pain and lameness to a greater extent [3]. treatment with ketoprofen (40 and 80 mg/kg diet) greatly reduced the incidence of transitional cell carcinoma of the urinary bladder by >70% from that seen in dietary mice [4].

Drug interactions

Potentially hazardous interactions with other drugs
ACE inhibitors and angiotensin-II antagonists: antagonism of hypotensive effect; increased risk of nephrotoxicity and hyperkalaemia
Analgesics: avoid concomitant use of 2 or more NSAIDs, including aspirin (increased side effects);avoid with ketorolac (increased risk of side effects and haemorrhage).
Antibacterials: possibly increased risk of convulsions with quinolones
Anticoagulants: effects of coumarins and phenindione enhanced; possibly increased risk of bleeding with heparins, dabigatran and edoxaban - avoid long term use with edoxaban
Antidepressants: increased risk of bleeding with SSRIs and venlaflaxine.
Antidiabetic agents: effects of sulphonylureas enhanced.
Antiepileptics: possibly increased phenytoin concentration.
Antivirals: increased risk of haematological toxicity with zidovudine; concentration possibly increased by ritonavir.
Ciclosporin: may potentiate nephrotoxicity.
Cytotoxics: reduced excretion of methotrexate; increased risk of bleeding with erlotinib.
Diuretics: increased risk of nephrotoxicity; antagonism of diuretic effect, hyperkalaemia with potassium-sparing diuretics.
Lithium: excretion decreased.
Pentoxifylline: increased risk of bleeding
Probenecid: excretion reduced by probenecid.
Tacrolimus: increased risk of nephrotoxicity

Metabolism

Dexketoprofen is the S-enantiomer of ketoprofen.The main elimination route for dexketoprofen is glucuronide conjugation in the liver followed by renal excretion.
