Conversions of deoxyradicinin to radicinin and of radicinin to 3-epi-radicinin in the phytopathogenic fungus Bipolaris coicis

Phytochemistry, 2012
Radicinin is a phytotoxic and antibiotic metabolite produced by some phytopathogenic fungi. Precursor administration and cell-free experiments with deoxyradicinin and radicinin were carried out in Bipolaris coicis H13-3. When deoxyradicinin was administered to the fungus, radicinin and 3-epi-radicinin formed.

Radicinin: A metabolite from Stemphylium radicinum. I. Chemistry and action

Archives of Biochemistry and Biophysics, 1955
Abstract The conditions for the growth of Sterad and isolation of radicinin are described. The formula C12H12O5 was established for this compound by preparation and analyses of several derivatives. Degradation and spectrophotometric studies were employed to establish the molecular formula.

An efficient synthesis of radicinin analogues

Tetrahedron, 1995
Abstract We describe herein an enantio- and diastereoselective total synthesis of two radicinin analogues 13 and 14. 13 has been subjected to biological tests, exhibiting the lowest toxicity of all radicinin analogues that have been investigated to date and it depresses the heart ventricular strip and histamine contraction.

Phytotoxins from Alternaria helianthi: radicinin, and the structures of deoxyradicinol and radianthin

Phytochemistry, 1985
Abstract A novel compound, radianthin, with phytotoxic activity was isolated from liquid cultures of Alternaria helianthi and identified as a pyrone related to radicinin. A second metabolite was identified as radicinin itself while deoxyradicinol is described for the first time as a natural product.

Radicinin from Cochliobolus sp. inhibits Xylella fastidiosa , the causal agent of Pierce’s Disease of grapevine

Phytochemistry, 2015
The fastidious phytopathogenic bacterium, Xylella fastidiosa, poses a substantial threat to many economically important crops, causing devastating diseases including Pierce's Disease of grapevine. Grapevines (Vitis vinifera L.) planted in an area under Pierce's Disease pressure often display differences in disease severity and symptom expression, with ...
