Common NameLuteoskyrin
DescriptionLuteoskyrin belongs to the class of organic compounds known as naphthols and derivatives. These are naphthalene derivatives carrying one or more hydroxyl (-OH) groups at any ring position. Luteoskyrin is an extremely weak basic (essentially neutral) compound (based on its pKa). Luteoskyrin is a potentially toxic compound. It is known to be a storage mold contaminant of rice and has been shown to be hepatotoxic and hepatocarcinogenic. Luteoskyrin is also hepatocarcinogenic, possibly a result of its ability to induce DNA fragmentation. It is thought that this is a result of its metabolic reduction to the semiquinone radical catalyzed by NADPH-dependent cytochrome reductases in the liver, leading to the generation of active oxygen species in redox systems. In the liver it is reduced to its semiquinone radical by NADPH-dependent cytochrome reductases. Luteoskyrin is a mycotoxin produced by the fungus Penicillium islandicum. Luteoskyrin accumulates selectively in the liver, with minor distribution to the serum and kidneys. It is able to bind to DNA, forming chelate-complexes with nucleic acids and select metal ions. cirrhosis and liver tumors. This causes the induction of lipid peroxidation, hepatocellular membrane damage, and elevation of serum transaminase activities, resultin in liver injuries. This compound has been identified in human blood as reported by (PMID: 31557052 ). Luteoskyrin is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Luteoskyrin is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources.
