Highly Potent Fluorogenic Ligands for Triplex DNA: 5‐Substituted 2‐(Naphthalen‐2‐yl)‐4H‐Chromen‐4‐Ones

Chemistry – A European Journal, EarlyView.
5‐Substituted 2‐(naphthalen‐2‐yl)‐4H‐chromen‐4‐ones are reported as a novel class of highly potent and selective triplex DNA ligands. These ligands induce triplex formation at submicromolar concentrations and inhibit enzymatic activity via ligand‐mediated triplex formation.

Late‐Stage Modification of Halotryptophan‐Containing Peptides Via Negishi Cross‐Coupling

Chemistry – A European Journal, EarlyView.
Negishi cross‐coupling provides access to the late‐stage functionalization of bromotryptophan‐containing peptides under comparatively mild conditions and is applicable to a range of peptide substrates in the investigated model systems. The examined alkyl iodides and variation of N‐terminal residues demonstrate the feasibility of the transformation in a

Successive Azide and DNA Functionalization for Reversible and Controlled Association of Single‐Wall Carbon Nanotubes

Chemistry – A European Journal, EarlyView.
A newly synthesized bifunctional azide—diazonium linker allows robust one‐step introduction of azido groups to single‐wall carbon nanotubes. Versatility of the azido groups as reactive handles is demonstrated by further derivatization with 6‐carboxyfluorescein and oligonucleotides.
