SYNTHESIS OF AZA-HETEROCYCLIC MONOAMIDINES AS POTENTIAL DNA MINOR
Abstract
A series of combilexin-like monoamidines has been synthesized by linking an intercalative unit with the DNA minor groove binder DB 818 via “Click chemistry.” DB 818 is a dicationic minor groove binder that has shown strong binding affinity to AT sequences. The aim was to synthesize novel classes of DNA minor groove binders that are combilexin-like – minor groove binder / intercalator hybrid – as potential unique DNA binding agents and therapeutics against African Sleeping Sickness. Additionally, a series of novel benzo[d]1,3,2-diazaboroles DAPI derivatives were also synthesized and investigated. These boron compounds ave the potential to be strong DNA minor groove binders because of their lower pKa and act as potential chromophores for Boron Neutron Capture Therapy.
