l-β,β-Dimethylmethionine S-oxide is a unique amino acid found in polytheonamides. Four designed hexapeptides containing the sulfide, (SR)-sulfoxide, (SS)-sulfoxide, and sulfone derivatives of l-dimethylmethionine were synthesized and functionally analyzed. Our results indicate that the sulfoxide stereochemistry of the peptides controls their overall physicochemical properties.
1 -β,β-二甲基甲硫氨酸S-氧化物是一种在聚乙酰胺中发现的独特氨基酸。合成了四个设计的六肽,它们含有硫化物,(S R)-亚砜,(S S)-亚砜和1-二甲基甲硫氨酸的砜衍生物,并对其功能进行了分析。我们的结果表明,肽的亚砜立体化学控制着它们的整体物理化学特性。
