ABSTRACT
The duocarmycins belong to a class of agent which has great potential for use in cancer therapy. Their exquisite potency means they are too toxic for systemic use, and targeted approaches are required to unlock their clinical potential. In this study, we have explored seco-OH-chloromethylindoline (CI) duocarmycin-based bioprecursors for their potential for cytochrome P450 (CYP)-mediated cancer cell kill. We report on synthetic and biological explorations of racemic seco-CI-MI, where MI is a 5-methoxy indole motif, and dehydroxylated analogues. We show up to a 10-fold bioactivation of de-OH CI-MI and a fluoro bioprecursor analogue in CYP1A1-transfected cells. Using CYP bactosomes, we also demonstrate that CYP1A2 but not CYP1B1 or CYP3A4 has propensity for potentiating these compounds, indicating preference for CYP1A bioactivation.

Fabulous at five! When ChemistryOpen was launched in 2011, it was the first society-owned general chemistry journal to publish open-access articles exclusively. Five years down the line, it has featured excellent work in all fields of chemistry, leading to an impressive first full impact factor of 3.25. In this Editorial, read about how ChemistryOpen has grown over the past five years and made its mark as a high-quality open-access journal with impact.
