Latonduines A and B, new alkaloids isolated from the marine sponge Stylissa carteri: structure elucidation, synthesis, and biogenetic implications.

چکیده
[structure: see text] Latonduines A (6) and B (7), two new alkaloids with unprecedented heterocyclic skeletons, have been isolated from the Indonesian marine sponge Stylissa carteri. The structures of the latonduines were elucidated by analysis of spectroscopic data and confirmed by the total synthesis of latonduine A (6). It is proposed that ornithine is the biogenetic precursor to the aminopyrimidine fragment of the latonduines.

Oxocyclostylidol, an intramolecular cyclized oroidin derivative from the marine sponge Stylissa caribica.
Pyrrole-imidazole alkaloids are widely distributed in marine sponges of the orders Halichondrida and Agelasida. Chemical investigation of the Caribbean sponge Stylissa caribica has led to the isolation of the first brominated pyrrole-imidazole alkaloid containing an oxidized pyrrole moiety. The isolation and structure elucidation of oxocyclostylidol (1) are discussed in detail.

The sponge Stylissa carteri is known to produce a number of secondary metabolites displaying anti-fouling, anti-inflammatory, and anti-cancer activity. However, the anti-viral potential of metabolites produced by S. carteri has not been extensively explored. In this study, an S. carteri extract was HPLC fractionated and a cell based assay was used to evaluate the effects of HPLC fractions on pa...
متن کاملUnprecedented stylissazoles A-C from Stylissa carteri: another dimension for marine pyrrole-2-aminoimidazole metabolite diversity.
The pyrrole-2-aminoimidazole (P-2-AI) alkaloids have been exclusively reported to be isolated from marine sponges. The P-2-AIs are well known for their dense structures with a very low carbon/nitrogen (mainly nxC11N5) ratio. [1] Their intriguing dimeric polycyclic ring systems that were isolated during the last years revealed their elaborate structures and molecular diversity which arise from a...

A main goal of population geneticists is to study patterns of gene flow to gain a better understanding of the population structure in a given organism. To date most efforts have been focused on studying gene flow at either broad scales to identify barriers to gene flow and isolation by distance or at fine spatial scales in order to gain inferences regarding reproduction and local dispersal. Few...
متن کاملNew antifeedant bromopyrrole alkaloid from the Caribbean sponge Stylissa caribica.
In this first report on the chemistry of the sponge Stylissa caribica, two known bromopyrrole metabolites and a new compound, N-methyldibromoisophakellin (1), were isolated and identified. The structure of 1 was determined using spectroscopic methods and the computer program COCON. N-Methyldibromoisophakellin (1) was shown to be the only secondary metabolite in Stylissa caribica that, at its na...
