Results and discussion
Any other information on results incl. tables
RM-Freetext:
Sulofenur is suggested to undergo bioactivation in vivo to
the reactive p-chlorophenyl isocyanate which, in turn, is
trapped in the form of GSH adduct and processed further to
the corresponding N-acetyl-L-cysteine conjugate.
