Journal ArticleDOI
The lycopodium alkaloids
TL;DR: This review covered the structure elucidation and biological activity of new Lycopodium alkaloids and total synthesis of some Lycop sodium alkaloid reported in the literature from 2004 to July in 2008.
Journal ArticleDOI
Amphidinolides, bioactive macrolides from symbiotic marine dinoflagellates
Jun'ichi Kobayashi,Masashi Tsuda +1 more
TL;DR: In this article, the structures, synthesis, biosynthesis, and bioactivity of a series of cytotoxic macrolides, named amphidinolides, isolated from symbiotic marine dinoflagellates of the genus Amphidinium which were separated from inside cells of marine flatworms.
Journal ArticleDOI
Celogentins A-C, new antimitotic bicyclic peptides from the seeds of Celosia argentea.
TL;DR: Structural-activity relationship study indicates that the bicyclic ring system including unusual non-peptide connections among beta(s)-Leu, Trp, and His residues characteristic of celogentins and moroidin, with ring size and conformations suitable for interaction with tubulin would be important for their biological activity.
Journal ArticleDOI
Calyciphyllines A and B, two novel hexacyclic alkaloids from Daphniphyllum calycinum.
TL;DR: Two types of Daphniphyllum alkaloids with unprecedented fused-hexacyclic ring systems have been isolated from the leaves and the structures and relative stereochemistry were elucidated on the basis of spectroscopic data.
Journal ArticleDOI

Masashi Tsuda,Takao Mugishima,Kazusei Komatsu,Teruo Sone,Michiko Tanaka,Yuzuru Mikami,Motoo Shiro,Manabu Hirai,Yasushi Ohizumi,Jun'ichi Kobayashi +9 more
TL;DR: A pentacyclic oxindole alkaloid, speradine A (1), was isolated from the cultured broth of a fungus Aspergillus tamarii, which was separated from driftwood at a seashore in Okinawa as mentioned in this paper.
