Antiviral activity of animal venom peptides and related compounds [PDF]

open access: yes, 2017
Viruses exhibit rapid mutational capacity to trick and infect host cells, sometimes assisted through virus-coded peptides that counteract host cellular immune defense.

Enhanced Ohmyungsamycin A Production via Adenylation Domain Engineering and Optimization of Culture Conditions

open access: yesFrontiers in Microbiology, 2021
Ohmyungsamycins (OMSs) A and B are cyclic depsipeptides produced by marine Streptomyces strains, which are synthesized by a non-ribosomal peptide synthetase. Notably, OMS A exhibits more potent activity against Mycobacterium tuberculosis and human cancer

Two New Cyclic Depsipeptides from the Endophytic Fungus sp

open access: yesNatural Product Communications, 2015
Two new cyclic depsipeptides, W493 C (1) and D (2), along with two known derivatives W493 A (3) and B (4) were obtained from the endophytic fungus Fusarium sp. isolated from the Mangrove plant Ceriops tagal.

Unraveling the senses of Phytophthora; leads to novel control strategies? [PDF]

open access: yes, 2009
Oomycetes cause devastating diseases on plants and animals. They cause major yield losses in many crop plants and their control heavily depends on agrochemicals. This is certainly true for the potato late blight pathogen Phytophthora infestans.

Visible‐Light Sensitized Isomerization in the Lipid Bilayer Enables Activation of a Transmembrane Transporter

open access: yesAngewandte Chemie, EarlyView.
A stiff‐stilbene‐based transmembrane anion transporter is isomerized by energy transfer from a ruthenium tris(bipyridyl) photosensitizer in the lipid bilayer. This sensitized isomerization allows activation of chloride transport using visible instead of UV light, without the need to chemically modify the stiff‐stilbene photoswitch.

Biological activities of ethanolic extracts from deep-sea antarctic marine sponges [PDF]

open access: yes, 2013
We report on the screening of ethanolic extracts from 33 deep-sea Antarctic marine sponges for different biological activities. We monitored hemolysis, inhibition of acetylcholinesterase, cytotoxicity towards normal and transformed cells and growth ...

Cyclodepsipeptides from Marine Sponges: Natural Agents for Drug Research

open access: yesMarine Drugs, 2010
A number of natural products from marine sponges, such as cyclodepsipeptides, have been identified. The structural characteristics of this family of cyclic peptides include various unusual amino acid residues and unique N-terminal polyketide-derived ...
