The structures of silver(I) complexes with cyclo(glycyl-l-histidyl), cyclo(l-methionyl-l-histidyl), and cyclo(l-histidyl-l-histidyl) were examined using 1H and 13C NMR. The NMR measurements suggest that the silver(I) ion links to the sulfur atom of thioether and the nitrogen atom of imidazole group of the above cyclic peptides, but not to their amide groups.
通过1H和13C NMR研究了银(I)与环状(甘氨酸-组氨酸)、环状(L-蛋氨酸-组氨酸)和环状(L-组氨酸-组氨酸)络合物的结构。NMR测量结果表明,银(I)离子与上述环状肽中的硫醚的硫原子及咪唑基团的氮原子相连接,但不与其酰胺基团结合。
