Abstract
Artemyriantholidimers A-G (1–7), seven undescribed guaiane-type sesquiterpenoid dimers (GSDs), and 27 known compounds (8–34) were isolated from Artemisia myriantha (Asteraceae). Their structures and relative configurations were elucidated based on the comprehensive analyses of UV, IR, MS, NMR data, quantum chemical NMR calculations with DP4+ probability analyses, and the absolute configurations were elucidated by ECD calculations. The undescribed GSDs (1–7) were presumably formed via Diels-Alder reactions, and compounds 5–7 were rare GSDs with α-configuration of H-6'. Compounds 4–7 showed significant inhibition on HepG2, Huh7, and SK-Hep-1 cells with IC50 values ranging from 6.9 to 13.0 μM by antihepatoma assay. The best active compound 5 was deduced to be targeted on the protein AURKA of the p53 signaling pathway by network pharmacological analysis with a high bind affinity of AURKA (total score: −8.98) by molecular docking, and had a KD value of 62.4 μM by surface plasmon resonance assay.
期刊介绍：
Phytochemistry is a leading international journal publishing studies of plant chemistry, biochemistry, molecular biology and genetics, structure and bioactivities of phytochemicals, including ''-omics'' and bioinformatics/computational biology approaches. Phytochemistry is a primary source for papers dealing with phytochemicals, especially reports concerning their biosynthesis, regulation, and biological properties both in planta and as bioactive principles. Articles are published online as soon as possible as Articles-in-Press and in 12 volumes per year. Occasional topic-focussed special issues are published composed of papers from invited authors.
