Synthesis and pharmacological properties of TOAC-labeled angiotensin and bradykinin analogs
(Elsevier B.V., 2002-01-01)
Angiotensin II (AngII) and bradykinin (BK) derivatives containing the TOAC (2,2,6,6-tetramethylpiperidine-N-oxyl-4-amino-4-carboxylic acid) spin label were synthesized by solid phase methodology. Ammonium hydroxide (pH 10, ...

First synthesis of a fully active spin-labeled peptide hormone
(Elsevier B.V., 1999-03-05)
For the first time in the electron spin resonance (ESR) and peptide synthesis fields, a fully active spin-labeled peptide hormone was reported. the ESR spectra of this alpha-melanocyte stimulating hormone (alpha-MSH) ...
Fmoc-POAC: [(9-fluorenylmethyloxycarbonyl)-2,2,5,5-tetramethylpyrrolidine-N-oxyl-3-amino-4-carboxylic acid]: A novel protected spin labeled beta-amino acid for peptide and protein chemistry
(Pharmaceutical Soc Japan, 2001-08-01)
The stable free radical 2,2,6,6-tetramethylpiperidine-N-oxyl-4-amino-4-carboxylic acid (TOAC) is the only spin labeled amino acid that has been used to date to successfully label peptide sequences for structural studies. ...

Peptide-lipid interaction monitored by spin labeled biologically active melanocortin peptides
(Elsevier B.V., 2005-10-01)
The present work comparatively analyzes the interaction of alpha-MSH and its more potent and long-acting analog [Nle(4), D-Phe(7)]alpha-MSH (NDP-MSH) with lipid bilayers. the peptides were spin labeled with Toac ...
Comparative EPR and fluorescence conformational studies of fully active spin-labeled melanotropic peptides
(Elsevier B.V., 2001-05-25)
Similar to melanocyte stimulating hormone (alpha -MSH), its potent and long-acting analogue, [Nle(4), D-Phe(7)]alpha -MSH, when labeled with the paramagnetic amino acid probe 2,2,6,6-tetramethylpiperidine-N-oxyl-4-amino- ...
