  Design, synthesis, and anti-inflammatory activity both in vitro and in vivo of new betulinic acid analogues having an enone functionality in ring A

  摘要：

  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. (c) 2006 Elsevier Ltd. All rights reserved.

  Synthesis and cytotoxic activity of a-ring modified betulinic acid derivatives

  摘要：

  New A-ring modified betulinic acid derivatives having small steric hindrance were prepared and tested for cytotoxic activity on 3 cancer cell lines: 10 compounds showed stronger cytotoxic activity than betulinic acid. Especially, the compounds bearing 1-ene-3-oxo with electron-withdrawing groups at C2 showed strong cytotoxicity. (C) 2003 Elsevier Ltd. All rights reserved.
