主 题：Giant taro Alocasia macrorrhiza Piperidine alkaloids Antiproliferative Apoptosis
摘 要：The rhizome of giant taro(Alocasia macrorrhiza(L.)Schott),which is a highly adaptable wild plant,is a traditional Chinese herbal *** the current study,the antiproliferative constituents of giant taro were investigated and six new(1−6)and four known piperidine alkaloids(7−10)were isolated from its *** chemical structures and absolute configurations were elucidated using various spectroscopic methods and the Mosher ester *** isolated alkaloids were screened for the antiproliferative activity through MTT *** results indicated that piperidine alkaloids exerted potential antiproliferative activity against HepG2,AGS and MCF-7 tumor *** researches showed that compounds 3−5 dose-dependently decreased the colony formation rate and induced the apoptosis of AGS cells,while compound 4 induced AGS cell death via the proapoptotic *** study demonstrates that the piperidine alkaloids isolated from giant taro exhibit significant antitumor activity,which provides phytochemical evidence for further development and utilization.
