Pentabromophenol  (Synonyms: PBP)

Pentabromophenol (PBP) is a brominated flame retardant (BFR) widely used in various consumer products to reduce the flammability of materials used in different utility items. Pentabromophenol can accelerate the degradation of transforming growth factor-β (TGF-β) receptors by promoting clathrin-mediated endocytosis, thereby inhibiting the TGF-β signaling pathway. Additionally, Pentabromophenol can also induce apoptosis in peripheral blood mononuclear cells (PBMCs)^[1][2].
