'''Genistein''' (C<sub>15</sub>H<sub>10</sub>O<sub>5</sub>) is a naturally occurring compound that structurally belongs to a class of compounds known as [[isoflavones]]. It is described as an [[angiogenesis inhibitor]] and a [[phytoestrogen]].<ref>{{Citation |last1=Sail |first1=Vibhavari |title=Chapter Eighteen - Notch Pathway Modulators as Anticancer Chemotherapeutics |date=2012-01-01 |url=http://www.sciencedirect.com/science/article/pii/B9780123964922000187 |volume=47 |pages=267–280 |editor-last=Desai |editor-first=Manoj C. |series=Annual Reports in Medicinal Chemistry |publisher=Academic Press |language=en |access-date=2020-09-14 |last2=Hadden |first2=M.

It was first isolated in 1899 from the [[Genista tinctoria|dyer's broom, ''Genista tinctoria'']]; hence, the chemical name. The compound structure was established in 1926, when it was found to be identical with that of '''prunetol'''. It was chemically synthesized in 1928.<ref>{{cite journal |last1=Walter |first1=E.

==Biological effects==
Besides functioning as an [[antioxidant]] and [[anthelmintic]], many [[isoflavone]]s have been shown to interact with [[animal]] and [[human]] [[estrogen receptor]]s, causing effects in the body similar to those caused by the [[estrogen|hormone estrogen]]. [[Isoflavone]]s also produce non-hormonal effects.{{Citation needed|date=April 2022}}

===Tyrosine kinase inhibitor===
The main known activity of genistein is [[tyrosine kinase inhibitor]], mostly of [[epidermal growth factor receptor]] (EGFR). Tyrosine kinases are less widespread than their ser/thr counterparts but implicated in almost all cell growth and proliferation signal cascades.{{citation needed|date=September 2014}}

===Cancer links===
Genistein and other [[isoflavone]]s have been identified as [[angiogenesis inhibitors]], and found to inhibit the uncontrolled cell growth of [[cancer]], most likely by inhibiting the activity of substances in the body that regulate [[cell division]] and cell survival ([[growth factors]]).

Genistein's chief method of activity is as a [[tyrosine kinase inhibitor]].

===Estrogen receptor&nbsp;— more cancer links===
Due to its structure similarity to 17β-estradiol ([[estrogen]]), genistein can compete with it and bind to [[estrogen receptor]]s.

''In vitro'' animal studies and clinical experiments suggest that the symptoms of the disease may be alleviated by adequate dose of genistein.<ref name="Piotrowska-2006">{{cite journal |last1=Piotrowska |first1=Ewa |last2=Jakóbkiewicz-Banecka |first2=Joanna |last3=Barańska |first3=Sylwia |last4=Tylki-Szymańska |first4=Anna |last5=Czartoryska |first5=Barbara |last6=Węgrzyn |first6=Alicja |last7=Węgrzyn |first7=Grzegorz |year=2006 |title=Genistein-mediated inhibition of glycosaminoglycan synthesis as a basis for gene expression-targeted isoflavone therapy for mucopolysaccharidoses |journal=European Journal of Human Genetics |volume=14 |issue=7 |pages=846–52 |pmid=16670689 |doi=10.1038/sj.ejhg.5201623 |doi-access=free}}</ref> Genistein was found to also possess toxic properties toward brain cells.<ref name="Jin-2007">{{cite journal |last1=Jin |first1=Ying |last2=Wu |first2=Heng |last3=Cohen |first3=Eric M. |last4=Wei |first4=Jianning |last5=Jin |first5=Hong |last6=Prentice |first6=Howard |last7=Wu |first7=Jang-Yen |year=2007 |title=Genistein and daidzein induce neurotoxicity at high concentrations in primary rat neuronal cultures |journal=Journal of Biomedical Science |volume=14 |issue=2 |pages=275–84 |pmid=17245525 |doi=10.1007/s11373-006-9142-2}}</ref> Among many pathways stimulated by genistein, [[autophagy]] may explain the observed efficiency of the substance as [[autophagy]] is significantly impaired in the disease.<ref name="Ballabio-2009">{{cite journal |last1=Ballabio |first1=A. |year=2009 |title=Disease pathogenesis explained by basic science: Lysosomal storage diseases as autophagocytic disorders |journal=International Journal of Clinical Pharmacology and Therapeutics |volume=47 |issue=Suppl 1 |pages=S34–8 |pmid=20040309 |doi=10.5414/cpp47034}}</ref><ref name="Settembre-2008">{{cite journal |last1=Settembre |first1=Carmine |last2=Fraldi |first2=Alessandro |last3=Jahreiss |first3=Luca |last4=Spampanato |first4=Carmine |last5=Venturi |first5=Consuelo |last6=Medina |first6=Diego |last7=de Pablo |first7=Raquel |last8=Tacchetti |first8=Carlo |last9=Rubinsztein |first9=David C. |last10=Ballabio |first10=Andrea |year=2007 |title=A block of autophagy in lysosomal storage disorders |journal=Human Molecular Genetics |volume=17 |issue=1 |pages=119–29 |pmid=17913701 |doi=10.1093/hmg/ddm289 |doi-access=free}}</ref>
