Product Describtion:
PDM 2 is an analog of resveratrol acting as a potent and selective Aryl Hydrocarbon Receptor (Ah Receptor, AhR) antagonist. The Ah Receptor is a ligand-dependent intracellular transcription factor whose ligands include some of the most infamous xenobiotics, including dioxin, benzo[a]pyrene, and numerous polyaromatics from soot and coal tar.
PDM2 is a selective, high-affinity aryl hydrocarbon receptor (AhR) antagonist with an Ki of 1.2±0.4 nM.

| Description | This compound belongs to the class of organic compounds known as stilbenes. These are organic compounds containing a 1,2-diphenylethylene moiety. Stilbenes (C6-C2-C6 ) are derived from the common phenylpropene (C6-C3) skeleton building block. The introduction of one or more hydroxyl groups to a phenyl ring lead to stilbenoids. |
