The Covalent Interaction Of Hepatic Metabolites Of The Insecticide Chlordane With Cellular Macromolecules In The Rat And Mouse In Vitro, Alan A. Brimfield

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This investigation addressed several aspects of the covalent interaction of metabolites of the insecticide chlordane with cellular macromolecules in vitro. Microsomal preparations from the liver of mice and rats were used and covalent binding to microsomal protein and RNA or to added calf thymus DNA was studied. Pure ¹⁴C-labelled cis- and trans-chlordane isomers as well as an isomeric mixture (¹⁴C-cis-chlordane plus ¹⁴C-trans-chlordane 3:1, w:w) were used as substrates for the in vitro system. Biochemical parameters investigated included inhibition of microsomal mixed-function oxidase and epoxide hydratase plus the induction of these enzymes by pretreatment with chlordane …
