ISOFLAVONES FROM LUPINUS ANGUSTIFOLIUS ROOT

Tow novel isoflavones, 5,7,2'-trihydroxy-6-(3,3-dimethylallyl)--isoflavone and 5,2',4'-trihydroxy-3'-(3,3-dimethylallyl)-isoflavone, have been isolated from the roots of Lupinus angustifolius cv.Uniharvest.Structures were established by analysis of 13C NMR and other spectral data, and by chemical conversion of one of the compounds to a coumaronochromone. Key Word Index--Lupinus angustifolius; Leguminosae; isoflavones; 13C NMR; coumaronochromone.

Coumarin Antifungal Lead Compounds from Millettia thonningii and Their Predicted Mechanism of Action

Fungal pathogens continue to pose challenges to humans and plants despite efforts to control them. Two coumarins, robustic acid and thonningine-C isolated from Millettia thonningii, show promising activity against the fungus Candida albicans with minimum

SYNTHESIS OF ALPINUM ISOFLAVONE, DERRONE AND RELATED PYRANOISOFLAVONES

Reaction of phenacylchroman 1 with ethoxyalyl chloride in pyridine followed by hydrolysis of the resulting esters 2 and 3 and decarboxylation of the acids 4 and 5, gave dihydro-4'-O-methyl alpinum isoflavone 6 and 4'-O-methylderrone 7 respectively.Similarly 8 gave 11 which was selectively demethylated to 7.DDQ, dehydrogenation of 6, 7 and 11 gave 14, 15 and 17.Demethylation of 6 and 7 followed by dehydrogenation gave alpinum isoflavone 18 and derrone 19.

A PYRANO-ISOFLAVONE FROM SEEDS OF MILLETIA THONNINGII

Extraction of the seeds of Milletia thonningii gave alpinumisoflavone, its monomethyl and dimethyl derivatives, robustic acid and a new pyrano-isoflavone.The structure of the latter was established by chemical transformation and spectroscopic means. - Key
