Biological Activity for Ceefourin 1

Ceefourin 1 is a selective MRP (multidrug resistance-associated protein) 4 inhibitor (IC50 = 2.6 μM). Selective for MRP4 over P-gp, MRP1 and ABCG2. Sensitizes MRP4 over-expressing cells to SN 38 (Cat. No. 2684). Ceefourin 1 inhibits cAMP efflux from acute myeloid leukemia cells (AML) and promotes apoptosis in combination with Histamine (Cat. No. 3545).

Programmed Cell Death Poster

There are two currently recognized forms of programmed cell death: apoptosis and necroptosis. This poster summarizes the signaling pathways involved in apoptosis, necroptosis and cell survival following death receptor activation, and highlights the influence of the molecular switch, cFLIP, on cell fate.
