Phytochemical investigation of the roots of Echinops latifolius led to the isolation of a new carbon skeleton dimeric sesquiterpene (1) and a new thiophene (2), along with six known compounds (3-8). Their structures and relative stereochemistry were elucidated by spectroscopic and spectrometric methods (H and C NMR, COSY, HSQC, HMBC, ROESY, and MS). All isolates were evaluated for their inhibition of LPS-induced NO production in RAW 264.7 cells. Compounds 4 and 5 exhibited the most potent inhibitory effects on NO production.
对宽叶蓝刺头根部进行植物化学研究，分离得到一个新的具有碳骨架的二聚倍半萜（1）和一个新的噻吩（2），以及六个已知化合物（3 - 8）。通过光谱和波谱方法（氢谱和碳谱核磁共振、COSY、HSQC、HMBC、ROESY和质谱）阐明了它们的结构和相对立体化学。评估了所有分离物对RAW 264.7细胞中脂多糖诱导的一氧化氮产生的抑制作用。化合物4和5对一氧化氮的产生表现出最有效的抑制作用。
