Benzosceptrin C, a new dimeric bromopyrrole alkaloid from sponge Agelas sp.
A new dimeric bromopyrrole alkaloid possessing a benzocyclobutane ring, benzosceptrin C (1), has been isolated from an Okinawan marine sponge of the genus Agelas (SS-956), and the structure andExpand
Brianodins A-D, briarane-type diterpenoids from soft coral Pachyclavularia sp.
Four new briarane-type diterpenoids, brianodins A-D ( 1- 4), were isolated from a soft coral, Pachyclavularia sp., and the structures and relative stereochemistry of 1- 4 were elucidated on the basisExpand
Bromopyrrole alkaloids from marine sponges of the genus Agelas.
TLDR
Four new bromopyrrole alkaloids were isolated from three collections of Okinawan marine sponges of the genus Agelas and the structures and stereochemistry of 1-4 were elucidated on the basis of their spectroscopic data. Expand
Agesamides A and B, bromopyrrole alkaloids from sponge Agelas species: application of DOSY for chemical screening of new metabolites.
TLDR
Diffusion-ordered NMR spectroscopy was applied for constituent analysis of crude bromopyrrole fractions separated from an Okinawan marine sponge Agelas sp. Expand
