Abstract
Thirty dihydroflavonol derivatives (D1–D30) were designed and synthesized, meanwhile the synthesized compounds were characterized on the basis of spectroscopic analyzes. Their inhibitory activity against the pro-inflammatory inducible interleukin-1β (IL-1β), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α) in lipopolysaccharide (LPS)-stimulated murine RAW 264.7 macrophages were evaluated and showed various efficiency. Compounds D1–D30 showed no toxic effects on RAW 264.7 cells at the concentration 20 μM; among them, compounds D9, D13, and D19 exhibited best anti-inflammatory activity through decreasing IL-1β, IL-6, and TNF-α. Furthermore, their structure–activity relationships were discussed preliminarily.
