Synthesis and bioactivities of novel 4,5,6,7-Tetrahydrothieno[2,3-c]pyridines as inhibitors of tumor necrosis factor-α (TNF-α) production

Novel 4,5,6,7-tetrahydrothieno[2,3-c]pyridine derivatives were synthesized and evaluated for their abilities to inhibit lipopolysaccharide (LPS)-stimulated production of TNF-α in rat whole blood. Several of these compounds exhibited potent inhibitory activity.
