产品描述:
Dicoumarol is a competitive inhibitor of NADH:quinone oxidoreductase (NQO1) with IC50 values of 2.6 and 404 nM in the absence and presence of 2 μM BSA, respectively.{38128} It has antiproliferative activity against MIA PaCa-2 pancreas and HCT116 colon carcinoma cells (IC50s = 52 and 19 μM, respectively, after a 96 hour incubation). Dicoumarol inhibits stress-activated protein kinase (SAPK) in HEK293 cells (IC50 = 19-33 μM) at a point upstream of MEKK1 and downstream of TNF receptor-associated factor 2 (TRAF2), and it inhibits TNF-α and LPS-induced NF-κB activation in HeLa cells.{38129} It also has antiproliferative activity against FL5.12 lymphocytic and MCF-7 breast carcinoma cells (100 μM) by suppressing JNK activation.{38130}
