Polyamide-Scorpion Cyclam Lexitropsins Selectively Bind AT-Rich DNA Independently of the Nature of the Coordinated Metal
Cyclam was attached to 1-, 2- and 3-pyrrole lexitropsins for the first time
through a synthetically facile copper-catalyzed “click” reaction.
The corresponding copper and zinc complexes were synthesized and characterized.
The ligand and its complexes bound AT-rich DNA selectively over GC-rich DNA, and
the thermodynamic profile of the binding was evaluated by isothermal titration
calorimetry. The metal, encapsulated in a scorpion azamacrocyclic complex, did
not affect the binding, which was dominated by the organic tail

Encoding microcarriers : present and future technologies
In answer to the ever-increasing need to carry out many assays simultaneously in drug screening and drug discovery, several microcarrier-based multiplex technologies have arisen in the past few years. The compounds to be screened are attached to the surface of microcarriers, which can be mixed together in a vessel that contains the target analyte. Each microcarrier has to be encoded to know which compound is attached to its surface. In this article, the methods that have been developed for the encoding of microcarriers are reviewed and discussed
