Metabolon Study Reveals Mechanisms of High Dosage Pentamethyl-6-Chromanol (PMCol) Toxicity in Liver Damage and Dysfunction

RESEARCH TRIANGLE PARK, N.C.--(BUSINESS WIRE)--Dec 8, 2011 - Metabolon, Inc., the leader in metabolomics, biomarker discovery and biochemical analysis, announced today the publication of “Toxicogenomics and Metabolomics of Pentamethylchromanol (PMCol)-Induced Hepatotoxicity” in the journal Toxicological Sciences. The study was conducted by the Biosciences Division of SRI International in conjunction with Metabolon scientists.

The study integrated classical toxicology, toxicogenomics, and metabolomic approaches to determine the mechanism of toxicity and identify sensitive early markers of target organ injury by PMCol.

Metabolomic evaluation of the liver and plasma samples found dose- and time-dependent effects, including depletion of total glutathione and glutathione conjugates, decreased methionine and cofactors FAD and NAD(P)+, and increased S-adenosylhomocysteine, cysteine, and cystine. Chronic exposure to high doses of PMCol induced liver damage and dysfunction that is likely due to two factors: the direct inhibition of glutathione synthesis and the modification of drug metabolism pathways.
