celastrus orbiculatus/유방암

Celastrus paniculatus is a traditional medicinal plant with diverse pharmacological activities. To identify its bioactive constituents, three new β-dihydroagarofuranoid sesquiterpenes were isolated from the whole plant, of which the major constituent is

Three new sesquiterpene polyol esters with a beta-dihydroagarofuran skeleton, NW12 (1), NW27 (2), and NW31 (4), together with a known compound, NW30 (3), were isolated from the root bark of Celastrus angulatus. Their chemical structures were elucidated by analyses of MS and NMR spectral data.

Celastrol, a triterpenoid isolated from stem (caulis) of Celastrus orbiculatus Thunb. (Celastraceae), has been known to have various pharmacological effects, including anti-inflammatory, anticancer, and antioxidant activities. However, the mechanism of the intestinal absorption of celastrol is
