isoflavones
Isoflavones are a class of naturally occurring polyphenolic compounds found in plants, where they function as secondary metabolites involved in defense responses and stress signaling. In plant biology, they are of particular interest because they represent a key branch of the flavonoid biosynthesis pathway, and understanding their production helps researchers explore how plants regulate chemical defenses and respond to environmental pressures. Their dual role as plant defense compounds and bioactive molecules with hormonal activity in mammals makes them a focal point for research into plant biochemistry and crop improvement.

Compounds extracted from kudzu root improved heart function in mice with a common form of heart failure by reshaping gut bacteria and shifting their metabolic output toward heart-protective molecules. The findings position kudzu isoflavones as credible drug candidates for a condition that currently has few treatment options.
Kudzu isoflavone extract significantly improved left ventricular diastolic dysfunction and reduced hypertension in a high-fat-diet/L-NAME mouse model of heart failure
Treatment increased beneficial gut-derived metabolites (butyrate and S-equol) while reducing harmful heart-linked compounds trimethyllysine (TML) and phenylacetylglycine (PAGly)
Kudzu isoflavones activated estrogen receptor β and the downstream eNOS-cGMP-PKG cardioprotective signaling axis while simultaneously suppressing the pro-inflammatory MAPK pathway
