Abstract:
Ten new diarylheptanoids (1-10), including five diarylether-type (1-5), three biaryl-type (6-8), and two linear type (9-10), along with eighteen known ones, were isolated from the fresh pericarps of Juglans hopeiensis Hu. Their structures were settled by integrated spectroscopic techniques, and their absolute configurations were determined by a combination of circular dichroism analysis, optical rotations, and NOESY experiments. Screening results showed that some isolated diarylheptanoids exhibited moderate neuroprotective effects on H2O2-induced or CoCl2-induced cellular damage in human neuroblastoma SH-SY5Y cells.
