Fifteen new betulinic acid analogues were designed, synthesized, and tested for anti-inflammatory activity. Many of these analogues effectively suppress nitric oxide (NO) production in RAW cells stimulated with interferon-gamma. Analogue 10 is highly and orally active in vivo for induction of the anti-inflammatory and cytoprotective enzyme, heme oxygenase-1.
