C₂₀H₂₈O₆

364.43

A cell-permeable inhibitor of NF-κB activity that displays antiproliferative (ED₅₀ ~ 2.7 µg/ml in lymphoid malignant cells) and antiangiogenic properties (significantly inhibits network formation of HMEC-1 cells at 2.5 µg/ml). Reported to affect DNA synthesis, induce apoptosis, and initiate cell cycle arrest. Shown to efficiently block both TNF-α and LPS-induced NF-κB activity in Jurkat and in RAW264.7 murine macrophages. Also inhibits p65 NF-κB transcriptional activity (IC₅₀ ~5 µg/ml in MT-1 cells) by disrupting NF-κB DNA-binding activity without interfering with its nuclear translocation.
