Tetrahydropyridine derivatives with inhibitory activity on the production of proinflammatory cytokines: Part 2

We previously reported a novel pyrrole derivative 1 which possesses a tetrahydropyridine group at the β-position with a proinflammatory cytokine TNFα production inhibitor. Herein, we report the synthesis and biological activity of N- and α-position substituted tetrahydropyridine derivatives. In this series, we found that compound 3o showed good inhibitory activity in vitro (inhibition of lipopolysaccharide (LPS)-induced TNFα production in human whole blood, IC50 = 0.44 μM) and compound 3i demonstrated potent inhibitory activity in vivo (inhibition of LPS-induced TNFα production in mice, ID50 = 1.42 mg/kg).
