Chemical investigation of extracts from the Irish deep-sea soft coral revealed cadinene-like sesquiterpenes, anthoteibinenes A-E, bearing unusual dimethylamine substitution. Structure elucidation was accomplished using 1D/2D NMR spectroscopy and high-resolution mass spectrometry, while NOESY NMR experiments, gauge invariant atomic orbital (GIAO) NMR calculations coupled with DP4+ probabilities measures, and ECD comparisons were incorporated to propose their relative and absolute configurations. Anthoteibinene B () exhibited 49% inhibition of respiratory syncytial virus (RSV) at 3.1 μM with no cytotoxicity.
从爱尔兰深海软珊瑚中提取的化学成分研究表明,含有不寻常二甲胺取代基的卡杜烯型倍半萜烯、anthoteibinenes A-E。结构鉴定采用了 1D/2D NMR 光谱和高分辨率质谱,同时还进行了 NOESY NMR 实验、基于 Gauge Invariant Atomic Orbital (GIAO) NMR 计算结合 DP4+概率测量和 ECD 比较,以提出它们的相对和绝对构型。Anthoteibinene B () 在 3.1 μM 时对呼吸道合胞病毒 (RSV) 的抑制率为 49%,且无细胞毒性。
