Effect of cultural conditions on the production of radicinin, a specific fungal phytotoxin for buffelgrass (Cenchrus ciliaris) biocontrol, by different Cochlioboulus australiensis strains

Natural Product Research, 2019
Radicinin is a phytotoxic fungal dihydropyranopyran-4,5-dione under evaluation for the development of a target-specific bioherbicide for invasive buffelgrass (Cenchrus ciliaris) control. It has already demonstrated high toxicity on host plants, low toxicity to native plants and no negative effects on zebrafish embryos.

Metabolic products of Stemphylium radicinum. Part III. Biosynthesis of radicinin and pyrenophorin

Journal of the Chemical Society C: Organic, 1970
Incorporation of [1-14C]acetate and [2-14C]malonate by the plant pathogenic fungus Stemphylium radicinum into the phytotoxic pyranopyrone radicinin gives a labelling pattern consistent with its formation by the condensation of two chains assembled from acetate-malonate-derived two-carbon units.

[Electrocardiographic changes induced by various analogs of radicinin].

Bollettino della Societa italiana di biologia sperimentale, 1983
The action of some radicinin analogues has been studied on the ECG in the rat. The most active compound is 2,3-dihydro-2, 7-dimethyl-4H,5H-pyrano [4,3-b]pyran-4,5-dione (II) which induced a significant increase of the heart rate (HR) and an evident prolongation of the PR interval, especially at the highest dose.
