Phaseollin Usage And Synthesis

Uses

Phaseollin is an isoflavonoid phytoalexin that can be isolated from Phaseolus vulgaris . Phaseollin is toxic to bean hypocotyl and endocarp cells, and causes a complete lysis of sheep erythrocytes[1].

Definition

ChEBI: A prenylated member of the class of pterocarpans and an organic heteropentacyclic compound that is 2,3,6b,12b-tetrahydro-1H,7H-chromeno[6',5':4,5]furo[3,2-c]chromen-10-ol in which both of the hydrogens at position 3 have been replaced by methyl groups (the R,R stereoisomer). It is found in found in the seeds of Phaseolus vulgaris (French bean) and in the stems of Erythrina subumbrans.
