Ketorolac ((rac)-5-benzoyl-1,2-3H-pyrrolo[1,2a] pyrrole1-carboxylic acid) is a non-steroidal anti-inflammatory drug (NSAID). It is used as a racemic mixture that contains a 1:1 ratio of the R(+) and S(?) stereoisomers. It is broadly used off-label as a parenteral analgesic in children. Ketorolac serves as a non-narcotic analgesic. It prevents the synthesis of prostaglandins, peripheral to the central nervous system.
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.
