Cytotoxic 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 کاملCytotoxic ent-kaurene diterpenoids from Isodon phyllostachys.
ent-Kaurene diterpenoids, phyllostachysins D-H (1-5), together with nine known compounds, rabdoloxins A-B (6-7), rabdoinflexin B (8), amethystoidin A (9), rabdokunmin D (10), macrocalyxin E (11), 5,7-dihydroxy-4'-hydroxylflavone (12), oleanolic acid (13) and daucosterol (14), were isolated from aerial parts of Isodon phyllostachys. Structures were elucidated on the basis of spectroscopic method...
متن کاملEnt-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...
