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.

[Effects of various radicinin analogs on pulse amplitude and arterial blood pressure].

Bollettino della Societa italiana di biologia sperimentale, 1983
The action of some radicinin analogues on the pulse amplitude in urethane anesthetized rats has been studied. The compounds used are:2,7-dimethyl-4H,5H-pyrano[4,3-b]pyran-4,5-dione (I); 2,3-dihydro-2,7-dimethyl-4H,5H-pyrano[4,3-b]pyran-4,5-dione (II) 7,8-dihydro-2,7-dimethyl-4H,5H-pyrano[4,3-b]pyran-4,5-dione (III) 2,3,7,8-tetrahydro-2,7-dimethyl-4H,5H-
