The structures of 1-7 were elucidated on the basis of spectroscopic data analysis. Compounds were evaluated for their antiproliferative activities against A549 and MCF-7 cancer cells, and among the substances tested, only 16-oxo-cleroda-3,13-dien-15-oic acid (8) exhibited cytotoxicity. ------>tmu_sno=None ------>sno=22752 ------>authors2=Wang MJ ------>authors3=Chen PY ------>authors4=Wu TY ------>authors5=Wen WT ------>authors6=Tsai FY, Lee CK ------>authors6_c= ------>authors=Lee TH ------>delete_flag=0 ------>SCI_JNo=None ------>authors2_c= ------>publish_area=0 ------>updateTitle=Constituents of Polyalthia longifolia var. pendula. ------>language=2 ------>check_flag=None ------>submit_date=None ------>country=None ------>no=12 ------>patent_SDate=None ------>update_bywho=None ------>publish_year=2009 ------>submit_flag=None ------>publish_month=12 |
