Bioactive Diterpenoids from Clerodendrum kiangsiense.
A new abeo-abietane diterpenoid, 12-methoxy-6,11,14,16-tetrahydroxy-17(15→16)-abeo-5,8,11,13-abietatetraen-3,7-dione (8), was isolated from the hydroalcoholic extract of the herb of Clerodendrum kiangsiense along with seven known diterpenoids (1-7). Their structures were identified on the basis of spectroscopic analyses including two-dimensional NMR and comparison with literature data. All of t...
متن کاملNeo-clerodane diterpenoids from Clerodendrum inerme.
Three neo-clerodane diterpenoids, inermes A, B and 14,15-dihydro-15 beta-methoxy-3-epicaryoptin, have been isolated from the hexane extract of the leaves of Clerodendrum inerme in addition to an epimeric mixture of 14,15-dihydro-15-hydroxy-3-epicaryoptin. Structures of these compounds have been elucidated on the basis of spectral studies.
متن کاملAframodial and other bioactive diterpenoids from Aframomum species
The biological activity of the potential therapeutic agent, 80,l 7-epoxy-1 2Elabdene-l5,16-dial (aframodial) 1, has been briefly reviewed. Ten other Cameroonian Aframomum species have been investigated as potentially improved sources for 1 and their aframodial content analyzed. In the course of these investigations three novel diterpenoids, aulacocarpinolide, aulacocarpin A, and aulacocarpin 6,...
متن کاملBioactive Eunicellin-Based Diterpenoids from the Soft Coral Cladiella krempfi
Four new eunicellin-based diterpenoids, krempfielins A-D (1-4), along with two known compounds (5 and 6) have been isolated from a soft coral Cladiella krempfi. The structures of the new metabolites were elucidated by extensive spectroscopic analysis and by comparison with spectroscopic data of related known compounds. Compounds 5 and 6 were shown to exhibit cytotoxicity against a limited panel...
متن کاملBioactive myrsinol diterpenoids from the roots of Euphorbia prolifera.
Ten myrsinol diterpenes, euphorbiaproliferins A-J (1-10), along with nine known analogues (11-19) were isolated from the roots of Euphorbia prolifera. Their structures were elucidated by spectroscopic data analysis (IR, ESIMS, HRESIMS, 1D and 2D NMR), and the structure of 1 was confirmed by X-ray crystallography. The diterpenes showed neuroprotective effects against MPP+-induced neuronal cell d...
