AA IVa reacted with 2'-deoxyadenosine (dA) and 2'- deoxyguanosine (dG) to form three dA and five dG adducts as identified by high-resolution mass spectrometry , among which two dA and three dG adducts were detected in reactions of AA IVa with calf thymus DNA (CT DNA ). (bvsalud.org)
However, no DNA adducts were detected in the kidney , liver , and forestomach of orally dosed mice at 40 mg/kg/day for 2 days, and bone marrow micronucleus assay also yielded negative results . (bvsalud.org)
The competitive reaction of AA I and AA IVa with CT DNA , with adducts levels varying with pH of reaction revealed that AA IVa was significantly less reactive than AA I, probably by hydroxyl deprotonation of AA IVa, which was explained by theoretical calculations for reaction barriers, energy levels of the molecular orbits , and charges at the reaction sites.
