Early Oxidative Transformations During the Biosynthesis of Terrein and Related Natural Products
Heterologous expression of two related biosynthetic gene clusters from Aspergillus terreus and Roussoella sp. DLM33 confirmed a conserved flavin‐dependent monooxygenase that initiates the oxidative decarboxylation of the key intermediate (dichloro‐) 6‐hydroxymellein. Further in vitro studies imply that both pathways diverge after this initial oxidation,

Photoactivated perylenequinone toxins in fungal pathogenesis of plants [PDF]
Several genera of plant pathogenic fungi produce photoactivated perylenequinone toxins involved in pathogenesis of their hosts. These toxins are photosensitizers, absorbing light energy and generating reactive oxygen species that damage the membranes of the host cells.

Perylenequinone Natural Products: Total Synthesis of Hypocrellin A [PDF]
An efficient and stereoselective total synthesis of the perylenequinone natural product hypocrellin A (1) is described. The key features include a potentially biomimetic 1,8-diketone aldol cyclization to set the centrochiral C7,C7'-stereochemistry, bis(trifluoroacetoxy)iodobenzene mediated oxygenation, a palladium-catalyzed decarboxylation, and an ...

Heterologous biosynthesis of elsinochrome A sheds light on the formation of the photosensitive perylenequinone system. [PDF]
Perylenequinones are a class of aromatic polyketides characterised by a highly conjugated pentacyclic core, which confers them with potent light-induced bioactivities and unique photophysical properties.

Despite sharing common global forcing factors, regional palaeoenvironmental conditions are perhaps more important in determining the sedimentary expression of OAE 1a. Pulses of fluvial fluxes associated with climate fluctuations played a key role in the development of intermittent, OM‐rich intervals in the Organyà Basin during carbon isotope segment C5

In this review, the authors summarize recent advances in theranostic agents for natural products categorized as porphyrins, perylenequinone, curcumin, and others. Some representative examples of disease diagnosis in fluorescence/photoacoustic imaging and disease treatment in PDT/SDT are introduced. Potential limitations and future perspectives of these

Cercospora beticola: The intoxicating lifestyle of the leaf spot pathogen of sugar beet
The hemibiotrophic fungus Cercospora beticola applies various virulence strategies to infect sugar beet and is currently only managed in‐field through integrated practices. Abstract Cercospora leaf spot, caused by the fungal pathogen Cercospora beticola, is the most destructive foliar disease of sugar beet worldwide. This review discusses C.
