New conceivable synthetic approach for the construction of nitrogen-rich 1,2,3-triazolo-pyrrolo[2,1-c] [1,4]benzodiazepine (TPBD, 3ac) trimers has been developed.The first example of a bis-1,2,3-triazolo-bridged unsymmetrical PBD trimer has been successfully synthesized by employing a CuAAC type 'click' chemistry protocol.This efficient route generates tri-imine functionality in a single molecule.It has been envisaged that such tri-imine functionalities could bring in efficient interaction with DNA in a sequence-selective manner in the minor groove of duplex DNA.One of the representative analogues 3c has shown improved DNA-binding ability (DTm 23.7 °C) by thermal denaturation studies using CT-DNA and this data is also supported by molecular modeling (MD) studies.
