Cat. No. 2816
Chemical Name: (4β,5β,6β,22R)-5,6-Epoxy-4,22,27-trihy
Biological ActivitySteroid lactone that displays anti-inflammatory, antitumor and antiangiogenic activity. Inhibits endothelial cells (HUVEC) sprouting in vitro (IC50 = 12 nM) and in vivo. Prevents NF-κB activation by inhibiting activation of IKKβ. Also inhibits chymotrypsin-like activity of the 20S proteasome.
