摘要

New derivatives of 3-oxoolean-1-en-28-oic acid and 3-oxours-1-en-28-oic acid were synthesized. Nine of them showed significant inhibitory activity against interferon-γ-induced nitric oxide production in mouse macrophages when assayed at the 1 μM level. 3, 12- Dioxoolean-1, 9-dien-28-oic acid (3) had the highest activity (IC50, 0.9 μM).
