متن کاملCytotoxic abietane diterpenes from Hyptis martiusii Benth.
From roots of Hyptis martiusii Benth. two tanshinone diterpenes were isolated, the new 7beta-hydroxy-11,14-dioxoabieta-8,12-diene (1) in addition to the known 7alpha-acetoxy-12-hydroxy-11,14-dioxoabieta-8,12-diene (7alpha-acetoxyroyleanone) (2). Structures of 1 and 2 were established by spectroscopic means. The cytotoxic activity against five cancer cell lines was evaluated. Compounds 1 and 2 d...
متن کاملNew abietane and seco-abietane diterpenes from the roots of Taiwania cryptomerioides.
Four new diterpenes, 3-oxosaprorthoquinone (1), 3-oxomicrostegiol (2), 3-oxoisotaxodione (3), and taiwaninal (4), together with two known compounds, 3-oxosapriparaquinone (5) and 6-dehydrohinokiol (6), were isolated from the roots of Taiwania cryptomerioides. The structures of 1-4 were principle elucidated based on spectral evidence.

Five new abietanes, three of them isolated as the corresponding acetate derivatives, i.e., 9alpha,13alpha-epidioxiabiet-8(14)-en-18-ol, 7alpha,18-diacetoxy, 9beta,13beta-epidioxiabiet-8(14)-ene, 7alpha,18-diacetoxyabiet-8(14)-en-13beta-ol, 7alpha,18-diacetoxy-13beta-methoxyabiet-8(14)-ene, and 13beta-hydroxyabiet-8(14)-en-7-one, were isolated from the neutral part of the hexane extract of the c...
متن کاملThree new abietane-type diterpenes from the bark of Cryptomeria japonica
Three new abietane-type diterpenoids, 7a-butoxyabieta-8,12-diene-11,14-dione (1), 6a,7a-dihydroxyabieta-8,12-dien-11,14-dione (2), and 6a,7b-dihydroxyabieta8,12-diene-11,14-dione (3) were isolated from the bark of Cryptomeria japonica D. Don. Their structures were established by means of 1D and 2D NMR, IR, UV, and HR-EI-MS spectra and comparison with the data of known analogues. ã 2016 Publishe...
