Shrnutí:(Chemical Equation Presented) What goes around... Cyclic mini-DNA duplexes, as shown in the scheme, have been synthesized in high yield on the multimicromole scale by using click chemistry. These B-like duplexes are very stable and bind to drugs, such as distamycin A and 7-aminoactinomycin D. Circular dichroism indicates that the bases are stacked, and UV melting and NMR spectroscopy showed that the interbase hydrogen bonds are very stable, even in a dimer. © 2008 Wiley-VCH Verlag GmbH and Co.
