The mechanism of the reaction of high temperature solid state catalytic isotope exchange (HSCIE) of hydrogen in peptides with spillover-tritium at 140-180 degrees C was analyzed. This reaction was used for preparing [(3)H]enkephalins such as [(3)H]DALG with specific activity of

Neurochemical research, 28(3-4), 599-606 (2003-04-05)
Comparative structure-function studies have been carried out for alpha-conotoxin GI acting on nicotinic acetylcholine receptors (AChR) from mammalian muscles and from the electric organ of the Torpedo californica ray and for alpha-conotoxin ImI, which targets the neuronal alpha7 AChR. A

Three homologous toxic peptides which cause postsynaptic inhibition at the vertebrate neuromuscular junction have been purified from the venom of the marine snail Conus geographus. Their amino acid sequences are: (formula see text) The biologically active peptides are monomeric, with

European journal of biochemistry, 268(13), 3664-3673 (2001-07-04)
Azidobenzoyl (AzBz) and benzoylbenzoyl (BzBz) derivatives of alpha-conotoxin MI and L-benzoylphenylalanine (Bpa) analogs of alpha-conotoxin GI were synthesized. All these compounds, similarly to native alpha-conotoxins, completely displaced the radioiodinated MI or GI from the membrane-bound nicotinic acetylcholine receptor (AChR) of

A bicyclic thioether analogue of alpha-conotoxin G1, a neurotoxin found in the venom of cone snails, was synthesized on solid phase. Two successive intramolecular on-bead cyclizations between a cysteine residue and a chloroacetylated reduced peptide bond are the key steps
