4'-Amino-[1,1'-biphenyl]-4-ol

4-Hydroxy-4'-aminobiphenyl (4-OH-4'ABP) is a test compound that is an aromatic aminobiphenyl and has been shown to be carcinogenic. This compound has been found in the urine and serum of human subjects as well as in the liver, lung and brain of experimental animals. 4-OH-4'ABP has been shown to cause cancer in target organs such as the liver and lung. It is also considered a carcinogen due to its ability to bind to DNA, inhibit protein synthesis, and induce oxidative stress. 4-OH-4'ABP can be hydroxylated at position 3 or 4 by cytochrome P450 enzymes into reactive metabolites which are then able to bind covalently with cellular macromolecules like DNA, proteins, or lipids. This binding can lead to mutations or cell death.
