摘要:
Together with the previously described (18R)-variabilin (1a), its 13Z-isomer 2a, ircinin 1 (3a) and ircinin 2 (4a), the corresponding sulfates 1b-4b were isolated from sponges of the genusIrcinia, collected in the Northern Adriatic Sea. The structural elucidation and biological activity of these compounds are reported.

摘要:
The incubation ofent-16β-hydroxykaurane (kauranol) withGibberella fujikuroigave a 11β-hydroxy derivative, which had been isolated earlier from this fungus, pointing to kauranol as a new alternative to a previously postulated precursor.

摘要:
A new approach to the synthesis of the cytotoxic marine sesterterpenoid (−)-12-deacetoxyscalaradial (1) is described. The starting product has been the methyl 18αH-scalar-16-en-19-oate (2), obtained according to a known procedure from manool (4).

摘要:
A new sulfated flavonol glycoside isorhamnetin 3-O-(4″-sulfatyl-rutinoside) (1) was isolated from the aerial parts ofZygophyllum dumosum, and its structure was determined by spectroscopic analysis and comparison with data for isorhamnetin 3-O-rutinoside (2), a compound also obtained from the same plant.
