摘要：
Japonicones A-C (1-3), three new dimeric lindenane-type sesquiterpenoids featuring a rare 12-membered ring framework, were isolated from the whole plants of Chloranthus japonicus Sieb. Their structures and absolute configurations were unequivocally established by a combination of spectroscopic data, ECD calculation, and X-ray crystallography. Compounds 1-3 were evaluated for their DNA Topoisomerase I (Top1) inhibitory, cytotoxic, and antibacterial activities. (C) 2019 Elsevier Ltd. All rights reserved.
