Biological Activity for Probenecid

Probenecid is an inhibitor of multidrug resistance-associated proteins (MRP). Probenicid inhibits OAT3, organic acid transport in the kidney and other organs and exhibits inhibitory activity against pannexin 1 channels (IC50 ~ 150 μM). Probenecid potently inhibits SARS-CoV-2 replication in NHBE and Vero E6 cells (IC50 = 1.3 nM and 750 nM, respectively) and reduces lung virus titers in vivo. Probenicid also inhibits influenza A virus replication in vitro and in vivo.

Compound Libraries for Probenecid

Probenecid is also offered as part of the Tocriscreen 2.0 Max, Tocriscreen Antiviral Library and Tocriscreen FDA-Approved Drugs. Find out more about compound libraries available from Tocris.

Programmed Cell Death Poster

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.
