title: [Novel conformational peptide antigen, which simulates an immunodominant epitope of the 2nd extracellular loop of β1-adrenoceptor. Computer simulation, synthesis, spatial structure].
abstract: By means of computer simulation has been built polypeptide antigen conformational structure that imitates the immunodominant epitope of the 2nd extracellular loop of β1-adrenoreceptor. A linear 25-membered peptide corresponding to calculated sequence was synthesized by means of solid-phase methoyd using Fmoc-technology, then directed by the closure ofdisulfide bridges was obtained original bicyclic polypeptide corresponding to the proposed structure of the conformational antigen. With the help of high-resolution NMR spectroscopy 3D structure of synthetic conformational antigen was investigated. It was shown that the structure of the bicyclic polypeptide similar to that of building computer model. Bicyclic conformational antigen was suitable for the detection of autoantibodies in the blood serum of patients with rhythm and conductivity violation without evidence of organic disease of the cardiovascular system.
