摘要：

Two new grayanoids, mollanol A (1) and rhodomollein XXV (2), were isolated from the fruits of Rhododendron molle. Their structures were elucidated by spectroscopic methods and X-ray diffraction analyses. Mollanol A (1) possesses a new C-nor-D-homograyanane carbon skeleton, while rhodomollein XXV (2) is the first example of an 11,16-epoxygrayanane and features a caged oxatricyclo[3.3.1.0(3.7)]nonane ring system. Plausible biogenetic pathways for 1 were proposed. Compound 1 exhibited transcriptional activation effects on the xbp1 upstream promoter in IEC-6, 293T, and RAW264.7 cells.
