A new cycloheptapeptide, cordyheptapeptide A (1), was isolated from the insect pathogenic fungus Cordyceps sp. BCC 1788 along with four known bioxanthracenes (2-5). The structure was elucidated by spectroscopic data. The absolute configuration of amino acid residues was determined by HPLC and X-ray diffraction analyses.
从昆虫病原真菌虫草菌BCC 1788中分离出一种新的环庚肽,即虫草环庚肽A(1),同时还分离出四种已知的生物蒽醌(2-5)。通过光谱数据阐明了其结构。通过高效液相色谱法和X射线衍射分析确定了氨基酸残基的绝对构型。
