BIOLOG
ical Activity

Inhibits DNA-dependent ATPase activity of XBP and induces inhibition of RNA polymerase II (RNAPII)-mediated transcription (IC
50
= 200 nM). Selective for RNAPII over RNAPI and RNAPIII. Blocks RNA synthesis in HeLa cells (IC
50
= 62 nM); exhibits potent antiproliferative activity in 60 cancer cell lines (average IC
50
= 12 nM) and induces apoptosis by blocking TNF-
α
-mediated c-IAP1 and c-IAP2 induction. Also displays immunosuppressive and anti-inflammatory activity.
