Abstract
Four 3-aminoindolizines were synthesized from the substituted 2-bromopyridines and propargyl amines with the aim of obtaining potential anti-inflammatory compounds, which were characterized by NMR, IR, ESI-MS and elemental analysis. Their biological activities were evaluated by the bacterial lipopolysaccharide (LPS) stimulation of mouse cells in the RAW264.7 inflammation model. The target compounds4a-4drevealed moderate anti-inflammatory effects with the inhibitions of 45%~61% at 50 μM. The bioactive 3-aminoindolizines might be used for further optimization as potential anti-inflammatory drugs.
