Upon oral ingestion of MCPG (43 mg/kg), a 50% decrease in blood glucose compared with controls was observed after 4 h. The plasma concentrations of lactate and non-esterified fatty acids were substantially increased during this period. The activity of general acyl-CoA dehydrogenase from isolated rat liver mitochondria was not significantly changed. By contrast, the activity of 2-methyl-(branched-chain)-acyl-CoA dehydrogenase decreased by over 80%. The enzyme activity of enoyl-CoA hydratase (crotonase) from pig kidneys decreased by 80% on incubation with the hypothetically toxic metabolite of MCPG, methylenecyclopropylformyl-CoA. These results suggest that the inhibition spectrum of MCPG is quite different from that of hypoglycin A and that similar physiological effects might result from inhibition of different enzymes of β-oxidation, e.g. hypoglycaemia and lacticacidemia. Accumulation of medium-chain acyl-CoA thioesters is probably at the origin of disturbances in pyruvate metabolism.</dcterms:abstract> <dspace:isPartOfCollection rdf:resource=""/> <dcterms:bibliographicCitation>First publ. in: Biochemical Journal 259 (1989), 3, pp. 921-924</dcterms:bibliographicCitation> <dcterms:isPartOf rdf:resource=""/> <dc:contributor>Ghisla, Sandro</dc:contributor> <void:sparqlEndpoint rdf:resource="http://localhost/fuseki/dspace/sparql"/> <dc:date rdf:datatype="">2011-03-24T17:38:13Z</dc:date> <dc:creator>Boschert, Wolfgang</dc:creator> <dc:language>eng</dc:language> <dc:creator>Buettner, Hermann</dc:creator> </rdf:Description> </rdf:RDF>
