(R)-(+)-Ketorolac

Chemical Properties

Off-White Solid

Uses

(R)-Ketorolac is the R-enantiomer of Ketorolac. The (S)-enantiomer is about 60 times more potent than (R)-enantiomer. Prostaglandin biosynthesis inhibitor. Analgesic; anti-inflammatory.

Definition

ChEBI: A 5-benzoyl-2,3-dihydro-1H-pyrrolizine-1-carboxylic acid that has R configuration. Unlike the S-enantiomer, it does not exhibit COX1 and COX2 inhibition, but does exhibit analgesic activity. Racemic keto olac, known simply as ketorolac, is used (mainly as a tromethamine salt) as a potent analgesic for the short-term management of post-operative pain, and in eye drops to relieve the ocular itching associated with seasonal allergic conjunctivitis.

Biochem/physiol Actions

R-Ketorolac is potent and selective Rho-family GTPases Cdc42 (cell division control protein 42) and Rac1 (Ras-related C3 botulinum toxin substrate 1) allosteric inhibitor that modulates downstream GTPase-dependent physiologic responses critical to tumor metastasis. R-ketorolac significantly inhibits ovarian cancer cell adhesion, migration, and invasion.
