Methoxyacrylates
Methoxyacrylates (more precisely β-methoxyacrylates) are a group of organic compounds primarily used as fungicides. They comprise an Acrylic acid, acrylic acid ester unit that also includes a methoxy group, making them a type of enol ether. Structure and effect The methoxyacrylate group is derived from strobilurins. Strobilurins feature a diene unit, which renders them only slightly photostable. In their synthetic analogs, this diene unit is typically replaced by other structural elements, usually aromatic rings. Methoxyacrylates inhibit cytochrome c oxidase, thereby blocking electron transport and the respiratory chain in the mitochondrion of fungi. Specifically, the active ingredients bind to the binding site for the oxidation of ubiquinol. The interruption of the respiratory chain prevents the biosynthesis of adenosine triphosphate, leads to energy deficiency and thus to the death of the fungi. The methoxyacrylate unit is critical to this inhibitory effect, which is why the a ...

Azoxystrobin
Azoxystrobin is a broad spectrum systemic fungicide widely used in agriculture to protect crops from fungal diseases. It was first marketed in 1996 using the brand name Amistar and by 1999 it had been registered in 48 countries on more than 50 crops. In the year 2000 it was announced that it had been granted UK Millennium product status. History In 1977, academic research groups in Germany published details of two new antifungal antibiotics they had isolated from the basidiomycete fungus '' Strobilurus tenacellus''. They named these strobilurin A and B but did not provide detailed structures, only data based on their high-resolution mass spectra, which showed that the simpler of the two had molecular formula C16H18O3. In the following year, further details including structures were published and a related fungicide, oudemansin A from the fungus '' Oudemansiella mucida'', whose identity had been determined by X-ray crystallography, was disclosed. When the fungicidal effects ...
