One new 6,7-seco-ent-kaurane diterpenoid, sculponin T （1）, was isolated from the aerial parts of lsodon sculponeatus, along with four known analogs, sculponeatin J （2）, sculponeatin K （3）, sculponeatin C （4）, and sculponeatin Q （5）. Their structures were elucidated by extensive spectroscopic analysis and by comparison with data reported in the literature. Significant cytotoxic activity was observed for compound 2 against five human tumor cell lines with IC50 values ranging from 1.8 μmol/L to 3.3 μmol/L, and it also inhibited NO production in LPS-stimulated RAW264.7 cells, with IC50 value of 3.3 μmol/L.

Constitutively active Wnt signaling frequently occurs in most colon ***,inhibitors of Wnt signaling pathway could provide rational therapeutic effects for colorectal *** this paper,we identified two inhibitors of Wnt signaling pathway,rabdoternin B and maoecrystal I from a natural ent-kauranoid library by a dualluciferase reporter gene *** two compounds inhibited Wnt signaling pathway in a concentration-dependent manner and exhibited selective cytotoxicity toward a number of colon carcinoma cell lines SW480,HCT116,and HT29,with only weak cytotoxicity towards the normal colonic epithelial cell line *** B and maoecrystal I treatment induced G2/M phase arrest efficiently in SW480 cells as revealed by flow cytometry analysis.A further study found that maoecrystal I decreased the expression of Wnt signaling target genes,including c-myc,cyclin D1,survivin and Axin2 in colon cancer *** our data suggests that rabdoternin B and maoecrystal I are novel inhibitors of canonical Wnt signaling pathway and may possess potentials for colon cancer therapy.
