PBB 169

Description:

PBB 169, or polybrominated biphenyl 169, is a member of the polybrominated biphenyl (PBB) family, which are brominated flame retardants. This compound is characterized by its chemical structure, which consists of two phenyl rings connected by a single bond, with multiple bromine atoms substituted on the rings. PBB 169 is known for its high thermal stability and effectiveness in reducing flammability in various materials, making it useful in plastics, textiles, and electronics. However, like other PBBs, it raises environmental and health concerns due to its persistence in the environment and potential bioaccumulation in living organisms. PBBs have been associated with various toxicological effects, including endocrine disruption and developmental issues in wildlife and humans. Regulatory measures in many countries have led to restrictions on the use of PBBs, including PBB 169, in consumer products. As a result, ongoing research focuses on understanding its environmental impact and exploring safer alternatives for flame retardancy.

3,3',4,4',5,5'-Hexabromobiphenyl is a brominated flame retardant that is used in the production of polymers and textiles. It has been detected in human adipose tissue at concentrations of up to 1.2 ng/g dry weight. 3,3',4,4',5,5'-hexabromobiphenyl has been shown to inhibit the production of uridine in mammalian cells. This inhibition may be due to its ability to form a complex with the enzyme uridine phosphorylase or it may be due to an indirect effect on cellular energy metabolism as it has been shown to enhance depression-like behavior in Sprague-Dawley rats and to inhibit liver cell proliferation. 3,3',4,4',5,5'-Hexabromobiphenyl also inhibits the growth of V79 cells and biphenyl uptake into these cells.
