Two unique low molecular weight (531) compounds with both digoxin-like immunoreactivity and Na, K-ATPase inhibitory properties have been isolated from human plasma. One of these, digoxin-like substance 2, (DLIS-2), was studied by fast atom bombardment mass spectrometry and collisionally activated dissociation mass spectrometry/mass spectrometry. The fragment patterns were interpreted as being derived from a lysophosphatidyl serine containing a novel 19:4 fatty acid side chain. The molecular formula C25H42O9NP is consistent with these observations.
从人血浆中分离出两种具有地高辛样免疫反应性和钠钾 - 三磷酸腺苷酶抑制特性的独特低分子量（531）化合物。其中一种地高辛样物质2（DLIS - 2），通过快原子轰击质谱法和碰撞激活解离质谱法/质谱法进行了研究。碎片图谱被解释为源自含有新型19:4脂肪酸侧链的溶血磷脂酰丝氨酸。分子式C25H42O9NP与这些观察结果一致。
