BACKGROUND
Alocasia macrorrhiza has been used as a folk medicine for cancer treatment in the Southwest of China.
OBJECTIVE
The purpose of this study is to confirm the anticancer activity of aqueous extract of alocasia macrorrhiza against hepatic cancer and to elucidate its mechanism of
BACKGROUND
Alocasia cucullata (Lour.) G. Don was applied in traditional Chinese medicine for the treatment of cancer in Chinese Southwest area. Its antitumor effect was scrutinized in vitro and in vivo. And for the first time, the mechanism of extract of A. cucullata (EAC) against human gastric
Ten steroids and iridoids were isolated from the tubers of Alocasia cucullata (Lour.) G. Don. Among them, alocasgenin A (1) and alocasgenoside B-C (2-3) were new compounds and the aglycone of compound 1, obtained from the acid hydrolysis of 1, was named alocasgenol (1a). Also, for the first time,
Six previously undescribed piperidine alkaloids were isolated from the rhizomes of Alocasia macrorrhiza (L.) Schott. Their structures were elucidated based on 1D and 2D NMR, IR, HR-ESI-MS spectroscopic analysis and the application of a modified Mosher method. All isolated alkaloids were evaluated
Five new indole alkaloids, alocasins A-E (3-7), together with known hyrtiosin B (1) and hyrtiosulawesin (2) were isolated from Alocasia macrorrhiza (L.) SCHOTT; their structures were elucidated on the basis of spectroscopic data. Compounds 1-7 were in vitro tested for cytostatic activity on human
An indole alkaloid, 2-(5-hydroxy-1H-indol-3-yl)-2-oxo-acetic acid (1) isolated for the first time from nature, in addition to the nine known compounds 5-hydroxy-1H-indole-3-carboxylic acid methyl ester (2), alocasin B (3), hyrtiosin B (4), α-monopalmitin (5), 1-O-β-D-glucopyranosyl-(2S, 3R, 4E,
An N-acetyl-D: -lactosamine (LacNAc) specific lectin from tubers of Alocasia cucullata was purified by affinity chromatography on asialofetuin-linked amino activated silica. The pure lectin showed a single band in SDS-PAGE at pH 8.8 and was a homotetramer with a subunit molecular mass of 13.5 kDa
Five new lignanamides (1-5), and one new monoindole alkaloid (6), along with eight known compounds (7-14) were isolated and identified from the rhizomes of Alocasia macrorrhiza (giant taro). All purified compounds were evaluated for their inhibitory effects on lipopolysaccharide (LPS)-induced nitric
Models of transplanted tumour in mice and human cancer enograft in nude mice were used to evaluate the antitumour effect of water extract of Alocasia macrorrhiza. Results showed that the inhibitory rate against S180 in mice was 29.38%, and the inhibitory rate against transplantable humman
Chinese herbal medicines have long been used to treat various illnesses by modulating the human immune response. In this study, we investigate the immuno-modulating effect and antitumor activity of Alocasia Cucullata (AC), a Chinese herb traditionally used to treat infection and cancer. We found
Alocasia cucullata, a Chinese herb, has been used as an anticancer treatment in southern China. Phosphatase and tensin (PTEN), is a tumor suppressor gene and the loss of PTEN expression may activate the phosphoinositide-3-kinase (PI3K)/AKT signaling pathway which play a key role in tumors formation
