Novel actinobacteria from marine sponges

Antonie van Leeuwenhoek, 2005
Actinobacteria exclusively within the sub-class Acidimicrobidae were shown by 16S rDNA community analysis to be major components of the bacterial community associated with two sponge species in the genus Xestospongia. Four groups of Actinobacteria were identified in Xestospongia spp., with three of these four groups being found in both Xestospongia ...

Marine Sponge Metagenomics

2015
The sponge is one of the oldest multicellular invertebrates in the world. Because of its special pore canal structure and characteristics of filter feeding, a large amount of microorganisms adhere to it. After hundreds of thousands of years’ evolution, they form a kind of symbiosis relationship.

Antimicrobial Activity of some Marine Sponges

Nature, 1969
THE evaluation of marine plants and animals for potential use in chemotherapy poses problems of procurement of materials and of techniques of screening for significant drug activity1. We have been studying antimicrobial activity in marine sponges both from the viewpoint of marine ecology and in an effort to develop new drugs, and report on our methods ...

Anticancer agents from marine sponges

Journal of Asian Natural Products Research, 2014
Marine sponges are currently one of the richest sources of anticancer active compounds found in the marine ecosystems. More than 5300 different known metabolites are from sponges and their associated microorganisms. To survive in the complicated marine environment, most of the sponge species have evolved chemical means to defend against predation. Such

[Bioactive compounds from marine sponges and cell culture of marine sponges].

Sheng wu gong cheng xue bao = Chinese journal of biotechnology, 2002
Presented a survey of bioactive compounds discovered from marine sponges in the recent five years, including the classes, distribution and their potential pharmaceutical uses. In particular, the compounds with antitumor, antivirus and antibacteria activity were discussed with their originating marine sponge species.

New tetrahydropyrans from a marine sponge

Tetrahedron, 1982
Two new tetrahydropyrans were isolated from the sponge Haliclona sp. From chemical and spectroscopic evidence they are shown to be (1''R,2S,2''E,5R,6R)-2-(1''-bromomethyl)-2,5-dimethyl-6-(penta-2'',4''-dienyl)tetrahydropyran and (1''R,2S,5R,6R)-2-(1''-bromomethyl)-2,5-dimethyl-6-(pent-4''-enyl)-tetrahydropyran.

NATURAL PRODUCT CHEMISTRY OF THE MARINE SPONGES

Pure and Applied Chemistry, 1976
A systematic search for constituents of marine sponges has yielded over one hundred new compounds, most of them with unique structural features. A broad survey of the field is presented and certain topics, particularly those closely related to recent work done in our own laboratory on sesquiterpenoids, are discussed in more detail.
