title: Synthesis and evaluation of S-4-(3-thienyl)phenyl-alpha-methylacetic acid.
abstract: Herein we report an efficient procedure to synthesize S-4-(3-thienyl)phenyl-alpha-methylacetic acid, an enantiomerically pure intermediate of a recently approved nonsteroidal antiinflammatory cyclooxygenase inhibitor, atliprofen [methyl RS-4-(3-thienyl)phenyl-alpha-methylacetate]. The interactions of the active S-isomer of the acid were theoretically compared with those of S-ibuprofen through molecular docking studies using COX-1 and COX-2 protein structures. The results were corroborated by in vitro and in vivo studies.
