Ent-kaurane diterpenoids from Isodon rubescens var. lushanensis.
Four new ent-kaurane diterpenoids lushanrubescensins F-I (1-4), together with 11 known ones, lasiodonin (5), oridonin (6), ponicidin (7), isodonoiol (8), isodonal (9), rabdosin B (10), rabdoternins A and B (11 and 12), enmenol (13), epinodosin (14), and inflexusin (15), were isolated from Isodon rubescens var. lushanensis, and the structures were elucidated by spectroscopic analysis. The inhibi...
متن کاملCytotoxic ent-kaurane diterpenoids from Isodon henryi.
Five new ent-kaurane diterpenoids, isodonhenrins A-E (1-5), together with thirteen known ones were isolated from the aerial parts of Isodon henryi. Their structures were identified by means of extensive spectroscopic analysis, and the absolute configurations of 1 were determined by single-crystal X-ray diffraction. Most of the diterpenoids were evaluated for their cytotoxicity against HL-60, SM...
متن کاملent-Atisane and ent-kaurane diterpenoids from Isodon rosthornii.
A new ent-atisanoid (1) and three new ent-kauranoids (2-4) belonging to different types, along with four known compounds were isolated from Isodon rosthornii. Their structures were established by means of extensive spectroscopic analysis. The absolute configuration of 1 was further determined by X-ray diffraction. Compounds 1 and 5 are the first example of atisane-type diterpenoid from this plant.
متن کاملNew ent-abietane and ent-kaurane diterpenoids from Isodon rubescens.
Five new ent-abietane diterpenoids, ent-abierubesins A-E (1-5), and two new ent-kauranoids, hubeirubesins A and B (6, 7), together with three known diterpenoids (8-10), were isolated from the aerial parts of Isodon rubescens. Their structures were identified by means of extensive spectroscopic analysis, and the absolute stereochemistry of 1 was determined by single-crystal X-ray diffraction exp...
متن کاملIsolation, structural elucidation, and cytotoxicity of three new ent-kaurane diterpenoids from Isodon japonica var. glaucocalyx.
Three new ENT-kaurane diterpenoids, glaucocalyxin H ( 1), glaucocalyxin I ( 2), and glaucocalyxin J ( 3), together with four known diterpenoids ( 4- 7), were isolated from the leaves of Isodon japonica Hara var. glaucocalyx. Their structures were elucidated by spectroscopic analysis, and the structures of compounds 2 and 3 were further confirmed by X-ray crystallographic analysis. Compounds 1, ...
