12a-Hydroxyamorphigenin

Isoflavonoids are also compounds that should be bom in mind for future cytotoxic studies with flavonoids. Isoflavones (aglycones with a 2-3 double bound, a 4 oxo group and the B-ring at C3 position) with the association of substituents mentioned above are not studied and could be. Besides, rotenoids are very cytotoxic isoflavonoids that are not well studied although one of them, 12a 3-hydroxyamorphigenin, is the most cytotoxic flavonoid found in our review, with values of less than 0.001 pg/mL on the six human cancer cell lines tested by Li et a/. [78].
