Abstract
A previously undescribed spirodiketopiperazine-indole alkaloid, chevalierlin (1), two pairs of previously undescribed dihydroisocoumarin enantiomers eurotiumides H–I (2–3), as well as six related known compounds (4–9) were isolated from the culture of a hydrothermal vent associated fungus Aspergillus chevalieri TW132-65. Their structures were unambiguously determined by NMR, mass spectrometry, and ECD calculations. Chevalierlin (1) exhibits moderate cytotoxic activities with IC50 values of 6.20 ± 0.05 μM and 7.68 ± 0.01 μM against Namalwa and Raji cell lines.
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.
