Publication: In vitro cytochrome P450 (CYP)- and transporter-mediated drug interaction potential of 6β-hydroxy-21-desacetyl deflazacort (6β-OH-21-desDFZ): A major human metabolite of deflazacort

This research article, published in Pharmacology Research & Perspectives, evaluates CYP- and transporter-mediated drug interaction potentials of 6β-OH-21-desDFZ 

  • Learn more about the pharmacokinetic drug interaction potential of 6 β-OH-21-desDFZ, a major circulating but not biologically active metabolite of deflazacort (DFZ)
  • The in vitro CYP- and transporter-mediated drug interaction potentials of 6β-OH-21-desDFZ is systematically evaluated
  • A novel approach to preparing radioactively labeled 14C-6β-OH-21-desDFZ using microbial biotransformation for transporter substrate assay is also presented
