A Mononuclear Scenario for the Copper‐Catalyzed Monooxygenation of Phenolic Substrates

Chemistry – A European Journal, EarlyView.
ABSTRACT Whereas a dinuclear pathway applies to the monooxygenation of phenols by the type 3 copper enzyme tyrosinase, a mononuclear pathway has been identified for the same reaction in corresponding small‐molecule systems. DFT calculations of five copper model complexes reveal that the latter mechanism is energetically feasible, identifying all ...

Streptomyces sp. VN1, a producer of diverse metabolites including non-natural furan-type anticancer compound

Scientific Reports, 2020
Streptomyces sp. VN1 was isolated from the coastal region of Phu Yen Province (central Viet Nam). Morphological, physiological, and whole genome phylogenetic analyses suggested that strain Streptomyces sp. VN1 belonged to genus Streptomyces. Whole genome

The Squalene Oil‐in‐Water Nanoemulsion Vaccine Carrier AddaVax Potentiates TLR‐Induced B‐Cell Responses

Cytometry Part A, EarlyView.
ABSTRACT For vaccination, the mechanisms of action of antigens and of immunostimulatory pathogen‐associated molecular pattern (PAMP) adjuvants are better understood than the roles of the depot, carrier, and other formulation‐related influences. Here, we carried out cytometric studies of vaccine formulations and the effect of adjuvant formulations on B ...

Streptomyces-derived nano-doxorubicin: Clinical status and patents granted [PDF]

Scripta Medica
Streptomyces have been presented as a great source of antibiotics and anti-cancer drugs over the past century. Especially Streptomyces living in adverse conditions produce certain metabolites with cytolytic and anti-microbial activities, which have been ...

A mutualistic interaction between Streptomyces bacteria, strawberry plants and pollinating bees

Nature Communications, 2019
Microbes can establish mutualistic interactions with plants and insects. Here we track the movement of an endophytic strain of Streptomyces bacteria throughout a managed strawberry ecosystem.
