An Investigation Into The Adduct Forming Potential Of Drugs Of Abuse With Peptides And Proteins, Richard Allen Gilliland

FIU Electronic Theses and Dissertations

Hemoglobin and serum albumin, two prevalent proteins in human blood, contain unbound cysteine thiol moieties, creating a nucleophilic site with the potential for covalent modification by reactive chemical species. These covalent modifications, called “adducts”, are stable entities that accumulate during acute and chronic exposure and remain covalently bound for the life-span of the protein. Despite their current use as exposure markers for a variety of compounds, the use of adducts in assessing exposure to drugs of abuse has not yet been explored. The goal of this work was to examine the in vitro adduct forming capability of selected drugs of …
