A convenient and scalable synthesis of ethyl N-[(2-Boc-amino)ethyl]glycinate and its hydrochloride. Key intermediates for peptide nucleic acid synthesis
Viirre, Russell D.,Hudson, Robert H. E.
, p. 1630 - 1632 (2003)
An improved synthesis of ethyl N-[(2-Boc-amino)ethyl]glycinate and its hydrochloride salt is reported. The synthesis is based on the reductive alkylation of Bocethylenediamine with ethyl glyoxylate hydrate and furnishes the title compound in near quantitative yield and high purity without chromatography. This compound is suitable, as is, for the synthesis peptide nucleic acid monomers. Further, conversion to the hydrochloride salt provides a stable, nonhygroscopic solid that is a convenient form for handling and storage.
Pharmaceuticals for enhanced delivery to disease targets

Page/Page column 10, (2010/02/14)
Pharmaceuticals for enhanced delivery to a disease target comprises a pair of compounds. The first compound comprises a first oligopeptide conjugated to a first moiety for coupling with a diagnostic or therapeutic active agent. The second compound comprises a second oligopeptide conjugated to a targeting species having a targeting moiety capable of binding to a target. The second oligopeptide has a sequence that is complementary to a sequence of the first oligopeptide. The first and second oligopeptides can be complementary PNA sequences. The pharmaceuticals are administered into a subject in methods for diagnosing or treating a disease condition, or assessing the effectiveness of a treatment of the disease condition.

The present invention discloses an improved synthesis of ethyl N-[(2-Boc-amino)ethyl]glycinate and its hydrochloride salt. The synthesis is based on the reductive alkylation of Boc-ethylenediamine with ethyl glyoxylate hydrate and furnishes the title compound in near quantitative yield and high purity without chromatography. This compound is suitable, as is, for the synthesis peptide nucleic acid monomers. Further, conversion to the hydrochloride salt provides a stable, non-hygroscopic solid that is a convenient form for handling and storage.

A novel class of peptide nucleic acids are described which include a conjugate attached thereto. The peptide nucleic acids generally comprise ligands such as naturally occurring DNA bases attached to a peptide backbone through a suitable linker.
Backbone modifications of aromatic peptide nucleic acid (APNA) monomers and their hybridization properties with DNA and RNA
Fader,Boyd,Tsantrizos
, p. 3372 - 3379 (2007/10/03)
Aromatic peptide nucleic acid (APNA) monomers containing N-(2-aminobenzyl)-glycine, N-(2-aminobenzyl)-(R)- or -(S)-alanine, and N-(2-aminobenzyl)-β-alanine moieties as part of their backbone were synthesized. These novel analogues were incorporated as a single "point mutation" in PNA hexamers, and their physicochemical properties were investigated by UV thermal denaturation and CD experiments. Destabilization in triplex formation between the PNA-APNA chimeras and complementary DNA or RNA oligomers was observed, as compared to the PNA control. The APNA monomer composed of the N-(2-aminobenzyl)-glycine backbone led to the smallest decrease in the thermal stability of the triplexes formed with DNA and RNA, while maintaining selectivity for base-pairing recognition. Since the PNA-APNA chimeras are more lipophilic than the corresponding PNA homopolymers, these oligomers may also exhibit better cell membrane permeability properties.
Multicomponent synthesis of novel amino acid-nucleobase chimeras: aA versatile approach to PNA-monomers
Maison, Wolfgang,Schlemminger, Imre,Westerhoff, Ole,Martens, Juergen
, p. 1343 - 1360 (2007/10/03)
This paper describes a multicomponent approach to novel totally protected precursors of PNA-monomers via Ugi 4CC. The obtained bisamides are converted into several partially protected PNA-monomers or derivatives thereof using three different procedures. Methods for hydrolysis are shown to be dependent on the nature of the isocyano component required for Ugi 4CC. Several novel monomers suitable for oligomer synthesis are prepared demonstrating the high versatility of the reaction sequence. Copyright (C) 2000 Elsevier Science Ltd.
Synthesis and photochemical behavior of peptide nucleic acid dimers and analogues containing 4-thiothymine: Unprecedented (5-4) photoadduct reversion
