Diversity and biosynthetic potential of culturable microbes associated with toxic marine animals [PDF]

, 2013
Tetrodotoxin (TTX) is a neurotoxin that has been reported from taxonomically diverse organisms across 14 different phyla. The biogenic origin of tetrodotoxin is still disputed, however, TTX biosynthesis by host-associated bacteria has been reported.

ANTIMICROBIAL METABOLITES FROM A MARINE-DERIVED FUNGUS

Indonesian Journal of Pharmacy, 2013
A marine fungus was separated from the surface of a marine red algae. Ethyl acetate extract of the cultivated marine fungus inhibited the growth of the pathogenic bacteria E.coli and S.aureus, and the phytopathogenic fungus C. cucurbitarum. Separation of the EtOAc extract gave four compounds, which were identified as new anthraquinonederivatives 3 and ...

Extent, characteristics and policy applications of Key Biodiversity Areas

Biological Reviews, EarlyView.
ABSTRACT A global standard for the identification of Key Biodiversity Areas (KBAs) was published 10 years ago to provide a unified set of criteria for identifying ‘sites of significance for the global persistence of biodiversity’. We review the initiative's origins, the KBA identification process, characteristics of the current network, threats, policy

Chemical Ligation of Backbone N‐hydroxylated Peptides

Chemistry – A European Journal, EarlyView.
Peptide backbone N‐hydroxylation enables sequence‐agnostic fragment ligation via hydroxamate O‐acyl capture and O→N acyl transfer in water. Broad tolerance of sterically demanding nucleophilic residues is observed, and reductive N─O cleavage restores the native amide bond.

Petromurin C Induces Protective Autophagy and Apoptosis in FLT3-ITD-Positive AML: Synergy with Gilteritinib

Marine Drugs, 2020
Treatment of acute myeloid leukemia (AML) remains inefficient due to drug resistance and relapse, particularly in patients with FMS-like tyrosine kinase 3 (FLT3)-internal tandem duplication (ITD).

Chalasoergodimers A–E, heterodimers with multiple polymerization modes from a marine-derived Chaetomium sp. fungus

Natural Products and Bioprospecting
Five new heterodimers, chalasoergodimers A–E (1–5), and three known heterodimers (6–8), along with four chaetoglobosin monomers (9–12), were isolated from a marine-derived Chaetomium sp. fungus.

Cytotoxic and Antimicrobial Compounds from the Marine-Derived Fungus, Penicillium Species

Molecules, 2018
The organic extract of liquid cultures of the marine-derived Penicillium sp. was investigated. Fractionation of the extracts of the fungus led to the purification and identification of two new compounds, penicillatides A (1) and B (2), together with the ...

THE ECOLOGY OF MUTUALISM [PDF]

, 1982
Elementary ecology texts tell us that organisms interact in three fundamen­ tal ways, generally given the names competition, predation, and mutualism. The third member has gotten short shrift (264), and even its name is not generally agreed on.

Secondary metabolites from the marine-derived fungus Phaeosphaeria spartinae

Natural Product Research, 2019
Investigation of the marine-derived fungus Phaeosphaeria spartinae led to the isolation of a new enantiomer of tricinonoic acid, namely (–)-tricinonoic acid (1), and a new polyketide spartinol E (2), together with three known compounds (3–5).
