bulbophyllum careyanum/悪性腫瘍

Orchids of the genus Bulbophyllum have been reported to possess antitumor activity. Present study investigated the possible antitumor activity of the active fraction of bulb and root of Bulbophyllum sterile. Alcoholic extract along with petroleum ether, dichloromethane and ethyl acetate fractions

A total synthetic route of two new dihydrostilbenes 5-(2-benzo[1,3]dioxole-5-ylethyl)-6-methoxy benzo[1,3]dioxole-4-ol (1) and 5-(2-benzo[1,3]dioxole-5-ylethyl)benzo[1,3]dioxole-4,7-diol (2), which were isolated from Bulbophyllum odoratissimum Lindl. with significant cytotoxicity toward human cancer

A new flavone C-glycoside, apigenin 6-C-α-arabinofuranosyl 8-C-α-arabinopyranoside (1) and a new bibenzyl, bulbotetusine (2), were isolated from the tubers of Bulbophyllum retusiusculum. Their structures were established on the basis of extensive spectroscopic analyses. The absolute configuration of

Three new dihydrodibenzoxepins 7,8-dihydro-5-hydroxy-12,13-methylenedioxy-11-methoxyldibenz[ B,F]oxepin (1), 7,8-dihydro-4-hydroxy-12,13-methylenedioxy-11-methoxyldibenz[ B,F]oxepin (2), and 7,8-dihydro-3-hydroxy-12,13-methylenedioxy-11-methoxyldibenz[ B,F]oxepin (3), were isolated from Bulbophyllum

Two new dimeric phenanthrenes, bulbophythrins A (1) and B (2), were isolated from Bulbophyllum odoratissimum. Their structures were elucidated by HR-ESI-MS, 1D and 2DNMR spectroscopy. They were evaluated in vitro for their inhibitory ability against the growth of human leukemia cell lines K562 and

A total synthetic route for two natural dihydrostilbenes with significant cytotoxicity toward human cancer cell lines, (3-(2-(7-methoxybenzo[d][1,3]dioxol-5-yl)ethyl)phenol 1a and 6-(3-hydroxyphenethyl)benzo[d][1,3]dioxol-4-ol 1b), which were isolated from Bulbophyllum odoratissimum Lindl, was
