Our findings support the mechanism of lapatinib CYP3A4 inactivation as MI complex formation with the nitroso metabolite formed through the secondary hydroxylamine and nitrone pathway , rather than by N - dealkylation to the primary amine followed by N - hydroxylation and dehydrogenation as is usually assumed .
 Chemical: lapatinib; Chemical: nitroso; Chemical: secondary hydroxylamine; Chemical: nitrone; Chemical: N; Chemical: primary amine; Chemical: N
