phaseollidin

Phaseollidin, an antimicrobial phytoalexin, is produced by Phaseolus vulgaris (French bean).

Phaseollidin hydrate shows less antifungal activity than the original phytoalexin phaseollidin.

1-Methoxyphaseollidin exhibits anti-Helicobacter pylori activity against the CLAR and AMOX-resistant strain as well as four CLAR (AMOX)-sensitive strains. 1-Methoxyphaseollidin may show moderate cytotoxic activity against KB and L1210 cells. 1-Methoxyphaseollidin also shows inhibition of lysoPAF acetyltransferase activity.

3,9-Dihydroxypterocarpan and phaseollidin are all good precursors of the pterocarpan phytoalexin phaseollin.
