摘要
Hyphenrones R–X(1–7), seven new polyprenylated acylphloroglucinols derivatives, were isolated from the fruits of Hypericum henryi, together with eight know analogues. Compounds 1 and 2 were elucidated to possess complex caged skeleton, while compounds 3–6 shared a common 3,9-epoxy moiety deriving from the normal polyprenylated acylphloroglucinols with a bicyclo[3.3.1]nonane-2,4,9-trione core. The new structures were elucidated on the basis of the interpretation of nuclear magnetic resonance(NMR) data, circular dichroism(CD) comparison, and single-crystal X-ray diffraction. In the bioassay, several compounds exhibited inhibitory activities against human tumor cell lines in vitro.
