The coumarin–pterocarpan conjugate – a natural product inspired hybrid molecular probe for DNA recognition

Abstract

Thermally induced cascade sigmatropic rearrangement of a butynyloxycoumarin derivative has led to a quick access to the coumarin–pterocarpan hybrid molecule. Biophysical studies together with molecular modeling show that this nature-inspired hybrid molecule is capable of binding to the minor groove of DNA as a non-conventional entity.
