      Steroid lactone that displays anti-inflammatory, antitumor and antiangiogenic activity. Inhibits endothelial cells (HUVEC) sprouting in vitro (IC50 = 12 nM) and in vivo. Prevents NF-?B activation by inhibiting activation of IKK?. Also inhibits chymotrypsin-like activity of the 20S proteasome. Tocris Bioscience 2816
