CP 100356 hydrochloride
High affinity P-glycoprotein (P-gp) inhibitor (Ki values are 58 and 94 nM for mouse Pgp1a and Pgp1b isoforms). Inhibits calcein-AM uptake in MDR1-transfected MDCKII cells (IC50 = 0.5 μM) and prazosin transport in BCRP-transfected MDCKII cells (IC50 = 1.5 μM). Displays weak or no inhibitory activity against MRP1, OATP1B1 and several major human P450 enzymes (IC50 > 50 μM).
Sold for research purposes under agreement from Pfizer Inc.

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.
