Four New 7,8-epoxycembranoids from a Chinese soft coral Lobophytum sp.
Four new 7,8-epoxycembranoids, namely (2S*,7S*,8S*,12R*,1Z,3E,10E)-7,8:2,16-diepoxycembra-1(15),3,10-trien-12-ol (1), (2S*,7S*,8S*,11R*,1Z,3E)-7,8:2,16-diepoxycembra-1(15),3,12(20)-trien-11-ol (2), (4S*,7S*,8S*,1Z,2E,11E)-16-acetoxy-7,8-epoxycembra-1(15),2,11-trien-4-ol (3), and (7S*,8S*,15S*,1E,3E,11E)-7,8-epoxycembra-1,3,11-trien-15,16-diol (4) were isolated from a Chinese soft coral Lobophytum sp., together with eleven known analogues 5-15. The structures of the new compounds were determined by extensive spectroscopic data analysis. All compounds were tested for the inhibitory effect on lipopolysaccharide (LPS)-induced nitric oxide (NO) production in mouse peritoneal macrophages (PEMΦ).
