Abstract
The first total synthesis of quinaldopeptin (1) was accomplished. Our approach to the synthesis of 1 includes the solid-phase peptide synthesis of the linear decapeptide 4 followed by macrocyclization and introduction of the quinoline chromophores 2 at a late stage of the synthesis. As for the preparation of 4, a fragment coupling approach was applied considering the C2 symmetrical structure of 1. Chromophore analogues 22 and 23 and desmethyl analogue 27 were also prepared in a manner similar to the synthesis of 1. Synthetic 1 exhibits a strong cytotoxicity with the IC50 value of 3.2 nM. On the other hand, the activity of 23 and 27 was largely reduced.

Abstract
Echinomycin is the prototypical bisintercalator, a molecule that binds to DNA by inserting two planar chromophores between the base-pairs of duplex DNA, placing its cyclic depsipeptide backbone in the minor groove. As such, it has been the focus of an extensive number of investigations into its biological activity, nucleic acid binding and, to some extent, its structure-activity relationships. However, echinomycin is also the parent member of an extended family of natural products that interact with DNA by a similar mechanism of bisintercalation. The structural variety in these compounds leads to changes in sequence selectivity and and biological activity, particularly as anti-tumour and anti-viral agents. One of the more recently identified marine natural products that is moving close to clinical development is thiocoraline, and it therefore seems timely to review the various bisintercalator natural products.
