title: Design, synthesis and bioactivities of novel diarylthiophenes: inhibitors of tumor necrosis factor-alpha (TNF-alpha) production.
abstract: The design, synthesis and SAR of novel diarylthiophene derivatives were performed. These compounds were designed by structural hybridization of TNF-alpha production inhibitors bearing 4-fluorophenyl and 4-pyridyl groups such as FR133605, FR167653 and SB210313, and 6-acetyl-3-ethoxycarbonyl-4,5,6,7-tetrahydrothieno[2,3-c]pyridine (1) found previously by us. As a result, several compounds were more potent in vitro than FR133605 against TNF-alpha production stimulated with lipopolysaccharide (LPS).
