Low-molecular-weight dendrons for DNA binding and release by reduction-triggered degradation of multivalent interactions

Chemistry. 2009 Jun 2;15(23):5656-60. doi: 10.1002/chem.200900420.

Abstract

Losing the grip: The synthesis of multivalent low-molecular-weight dendrons with lysine branching units coupled to disulfide-linked spermine surface groups is described. It is furthermore demonstrated that the dendrons bind DNA with good affinity (see image), but are also able to release the DNA in a reductive environment.
