Nitrogen-Containing Diterpenoids, Sesquiterpenoids, and Nor-Diterpenoids from Cespitularia taeniata
Two new nitrogen-containing verticillene diterpenoids, cespilamides A and B (1 and 2), three new nitrogen-containing sesquiterpenoids, cespilamides C-E (3-5), and five new norverticillene and verticillene diterpenoids, cespitaenins A-E (6-10), were isolated from the Taiwanese soft coral Cespitularia taeniata. Compound 1 possesses an unusual oxazo ring system at C-10 while compound 2 displays an...
متن کاملBioactive 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 کاملMinor diterpenoids from Scutellaria galericulata
Three new neo-clerodane diterpenoids, one C-16 epimeric pair, scutegalerins C and D, and scutegalerin E, together with the known scutaltisin B, were isolated from the acetone extractof the aerial parts of Scutellaria galericulata. The chemical structures of the new compounds were elucidated by spectroscopic techniques and a comparison with data of similar compounds as (13S,16R,19S)-6a-acetoxy-2...
متن کاملNew diterpenoids from the aerial parts of Salvia reuterana
The genus Salvia is a valuable origin of structurally diverse terpenoids. In a project directed at structurally interesting bioactive metabolites from Iranian Salvia species, we studied Salvia reuterana. Two new labdane diterpene, 6β,14α-dihydroxy-15-acetoxysclareol (1), and 14α,15- dihydroxy sclareol (2), were isolated from the aerial part of the plant. Their structures were established mainly...
