| 摘要 | Investigation of the 95% EtOH extract of stems of Dendrobium findlayanum afforded four new seco-dendrobines, findlayines A-D (1-4); two known dendrobines, dendrobine (5) and 2-hydroxydendrobine (6); and four new phenolic compounds, dendrofindlaphenols A-C (7, 9, and 10) and 6 ''-de-O-rnethyldendrofindlaphenol A (8). Compounds 1 and 2 are the first seco-dendrobines possessing a seven membered lactam moiety, with 3 and 4 derived from the oxidative cleavage of the C-2-C-3 bond of dendrobine. The structures were established using spectroscopic methods and by comparison with literature data. The absolute configurations of 1-4 were confirmed via single-crystal X-ray diffraction data. Cytotoxic activity assays against HL-60, SMMC-7721, A-549, MCF-7, and SW480 human cancer cell lines revealed IC50 values ranging from 2.3 to 5.3 mu M for compound 7, from 19.4 to 34.4 mu M for 8, and from 49.4 to 96.8 mu g/mL for the EtOAc extract. An assay of the inhibition of NO production with RAW 264.7 cells indicated that 8 had an IC50 value of 21.4 mu M, and the EtOAc extract, 10.5 mu g/mL. The EtOAc extract possessed DPPH radical scavenging activity of 69.93% at 100 mu g/mL. |
