General description

Genistein is an isoflavonoid present among Leguminosae family of plants. It is structurally similar to estrogen (estradiol-17β).

Application

Genistein has been used:
  • as a test compound to access its estrogeniic acivity
  • as an oestrogenic ligand to carry out identical reporter gene activation assays and also used to examine the binding of genistein to hERβ
  • as an endocytosis inhibitor to test the possible effect of endocytosed advanced glycation end - bovine serum albumin (AGE-BSA) on lysosomes

Biochem/physiol Actions

Genistein is essential for plant-microbe interaction. It acts as a natural chemoprotectant and helps in preventing tumor progression and heart disorders. Genistein functionally shares estrogen′s action. It is useful in evaluating nutraceuticals and functional foods. Genistein exhibits antimicrobial action and can serve as a phytoalexin and phytoanticipin.
Inhibitor of tyrosine protein kinase; competitive inhibitor of ATP in other protein kinase reactions. Antiangiogenic agent, down-regulates the transcription of genes involved in controlling angiogenesis.
