title: The interaction between resistance modifiers such as pyrido[3,2-g]quinoline, aza-oxafluorene and pregnane derivatives with DNA, plasmid DNA and tRNA.
abstract: Various resistance mechanisms such as complex formation with DNA, tRNA and MDR1 p-glycoprotein were modified in bacteria and cancer cells in presence of pregnane, pyridoquinoline, and aza-oxafluorene derivatives. Interaction between the compounds, plasmid DNA and tRNA was shown and compared to the interaction with calf thymus DNA. Complex formation with MDR1 p-glycoprotein and drug accumulation increased in cancer cells. Both plasmid DNA and p-gp complex formation were related to the chemical structures of the resistance modifiers.
