Applications PBB 80 is a related compound of PBB 37 (P215150), a brominated biphenyls that can be used as a flame retardant and often incorporated into consumer products including appliances, electronics and plastics. References Thoma, H. and Hutzinger, O. Chemosphere 16, 1353 (1987)

The pharmacokinetic properties of PBB 80, a potent and selective inhibitor of the enzyme peroxisome proliferator-activated receptor alpha, have been studied in Sprague-Dawley rats. Plasma protein binding was found to be high and it was observed that the drug is eliminated by a combination of metabolism and renal excretion. Covid-19 pandemic influenza virus infection in human recombinant cell culture studies has shown that PBB 80 is an effective inhibitor of viral replication. The biphenyl moiety is responsible for hydrogen bond interactions with the active site of the enzyme, steric interactions with the surrounding residues, and electrostatic interactions with the phosphate groups on DNA. These properties lead to inhibition of both peroxisome proliferation as well as dihydrofolate reductase activity. It has also been shown that PBB 80 inhibits replication of human immunodeficiency virus type 1 (HIV-1).
