Key result
Synthesized phenylquinoline-containing peptide binds RNA with ~208 nM affinity, suggesting potential antibacterial utility.
Why the study?
A new class of RNA-binding molecules based on 4,8-disubstituted 2-phenylquinoline amino acids was synthesized to explore their potential for high-affinity RNA binding and antibacterial agent discovery.
Effect estimate: K(D) = 208 nM
A newly synthesized phenylquinoline-containing peptide demonstrates nanomolar binding affinity to an RNA target, suggesting potential utility in developing new antibacterial agents.
Provides route to tunable quinoline peptides; leaves open RNA-targeting or antibacterial applications.
[reaction: see text] A synthesis of 4,8-disubstituted 2-phenylquinoline amino acids is reported with the incorporation of one example into a peptide by solid-phase synthesis. The phenylquinoline-containing peptide binds an RNA target with nanomolar affinity (K(D) = 208 nM). The strategy can be used to prepare a variety of 2-substituted quinoline amino acids for alteration of affinity in intercalator peptides. Since quinolones represent an important class of antibacterials, these compounds may be useful in the discovery of new antibacterial agents.

Krishnamurthy et al. (2003) studied this question. Peptide quinoline conjugates was evaluated on RNA target binding affinity (K(D) = 208 nM). A synthesized phenylquinoline-containing peptide binds an RNA target with nanomolar affinity (K(D) = 208 nM), suggesting potential utility in discovering new antibacterial agents.
