Synthesis and biological activity of benzamide DNA minor groove binders

A range of di- and triaryl benzamides were synthesised to investigate the effect of the presence and nature of a polar sidechain, bonding and substitution patterns and functionalisation of benzylic substituents. These compounds were tested for their antiproliferative activity as well as their DNA binding activity. The most active compounds in all assays were unsymmetrical triaryl benzamides with a bulky or alkylating benzylic substituent and a polar amino sidechain.
