Structural basis for G•C recognition in the DNA minor groove
Small molecules that target specific DNA sequences offer a potentially general approach for the regulation of gene expression. Pyrrole–imidazole polyamides represent the only class of synthetic small molecules...

Recognition of the four Watson–Crick base pairs in the DNA minor groove by synthetic ligands
The design of synthetic ligands that read the information stored in the DNA double helix has been a long-standing goal at the interface of chemistry and biology1,2,3,4,5. Cell-permeable small molecules that targe...

Regulation of gene expression by small molecules
Small molecules that target specific DNA sequences have the potential to control gene expression. Ligands designed for therapeutic application must bind any predetermined DNA sequence with high affinity and pe...

Recognition of DNA by designed ligands at subnanomolar concentrations
SMALL molecules that specifically bind with high affinity to any predetermined DNA sequence in the human genome would be useful tools in molecular biology and potentially in human medicine. Simple rules have b...

Faster rates with less catalyst in template-directed reactions
We have recently shown that the polycytidylic acid-directed polymerization of guanosine 5′-monophosphate 2-methylimidazolide (2-McImpG) is amenable to kinetic study and that rate determinations as a function o...

Affinity of guanosine derivatives for polycytidylate revisited
Evidence is presented for complexation of guanosine 5′-monophosphate 2-methylimidazolide (2-MeImpG) with polycytidylate (poly(C)) at pH 8.0 and 23°C in the presence of 1.0 M NaCl and 0.2 M MgCl2 in water. The ass...
