Synthesis of a PNA-encoded cysteine protease inhibitor library
摘要:
Peptide nucleic acids (PNAs) have been used to encode a combinatorial library whereby each compound is labeled with a PNA tag which reflects its synthetic history and localizes the compound upon hybridization to an oligonucleotide array. We report herein the full synthetic details for a 4000 member PNA-encoded library targeted towards cysteine protease. (C) 2004 Elsevier Ltd. All rights reserved.

Making the right signals: Reactions in which the DNA target acts as a catalyst allow amplifiedsignaling in the detection of DNA. The reactivity of the peptide nucleicacid (PNA) probes determines whether a given probe set provides high sensitivity or high selectivity. The careful adjustment of reactivity, probe affinity, and the use of a product‐selectivereadout method allows improvements in the

Pure and simple: A simple chimeric PNA (named chiPNA) was observed to selectively bind RNA in a 1:1 mixture of RNA and DNA with identical base sequences. This binding was assessed by chip‐based assay.
The reaction between maleimides and resin-linked diene–polyamides allows the latter to be used in the preparation of conjugates. Conjugation takes place by reacting the insoluble, hydrophobic diene component either with water-soluble dienophiles or with dienophiles requiring mixtures of water and organic solvents. Experimental conditions can be adjusted to furnish the target conjugate in good yield

hydrophobic and aromatic transmembrane peptide was covalently functionalized with a short peptide nucleicacid (PNA) used as specific outer-membrane recognition unit. The PNA sequences were chosen with high polarity to ensure localization within the aqueous phase. To estimate the impact of the membrane adjacent recognition on the TMD assembly by Förster resonance energy transfer (FRET), fluorescence probes were
