What is the Meaning of Enterolactone?

Enterolactone is a clinically relevant phytoestrogen, specifically a lignan metabolite, produced in the colon through the fermentation of dietary precursors by the gut microbiota. This compound possesses weak estrogenic activity and significant antioxidant properties, enabling it to interact with estrogen receptors, particularly Estrogen Receptor Beta, to subtly modulate hormonal signaling pathways. Its measurable concentration in the bloodstream serves as a valuable biomarker for dietary lignan intake and the functional status of the intestinal microbiome, linking nutrition directly to endocrine balance.

What is the Origin of Enterolactone?

The name is a combination of "entero-," referring to the intestinal tract where the metabolic conversion occurs, and "lactone," a chemical designation for a cyclic ester structure. The discovery of enterolactone was part of a broader research effort in nutritional science to understand the biological activity of plant-derived compounds and their potential protective effects against hormone-sensitive conditions like certain cancers.

What is the Mechanism of Enterolactone?

Dietary lignans, such as secoisolariciresinol diglucoside, are ingested and then efficiently converted by specific anaerobic bacteria in the large intestine into the biologically active form, enterolactone. Once absorbed into the circulation, enterolactone acts as a selective estrogen receptor modulator (SERM)-like agent, binding to estrogen receptors to influence the transcription of estrogen-responsive genes. This interaction can subtly influence cellular proliferation, differentiation, and overall hormonal homeostasis in target tissues.
