Urolithin M5 CAS NO.91485-02-8
<p><strong>Urolithin M5</strong> (CAS NO. 91485-02-8) is a high-purity, gut microbiota-derived metabolite belonging to the <strong>urolithin</strong> family (dibenzo-α-pyrones). It is a structural isomer of the more common Urolithin A, differing in the position of hydroxyl groups. Like other urolithins, it is formed via microbial transformation of ellagitannins. Urolithin M5 is a research compound of growing interes…

1.MECHANISM OF ACTION
- Estrogen Receptor Modulation (Potential Key Activity): Due to its specific hydroxylation pattern, Urolithin M5 is hypothesized to interact with estrogen receptors (ERα and ERβ). It may act as a phytoestrogen or selective estrogen receptor modulator (SERM), influencing estrogen-responsive tissues. This differentiates it from Urolithin A, which is not primarily known for estrogenic activity.
- Anti-inflammatory Action: Like other polyphenol metabolites, it likely exhibits anti-inflammatory properties, potentially by modulating pathways such as NF-κB and MAPK and inhibiting the production of pro-inflammatory cytokines (e.g., TNF-α, IL-6).
- Antioxidant Activity: It possesses inherent free radical scavenging ability due to its phenolic structure, contributing to cellular protection against oxidative stress.Cell Signaling & Metabolic Modulation: It may influence other cellular signaling cascades related to proliferation, apoptosis, and metabolism, though these require specific investigation.

2.PRODUCT INDICATIONS
- Comparative Urolithin & Structure-Activity Relationship (SAR) Research: Essential for mapping the distinct biological effects of different urolithin isomers to understand which structural features drive specific health benefits.
- Endocrinology & Women's/Men's Health Research: Investigating its potential as a natural SERM or phytoestrogen for conditions related to hormone balance, bone health, menopausal symptoms, or hormone-sensitive cancers (e.g., breast, prostate).
- Microbiome & Nutrigenomic Studies: As a specific metabolite to study inter-individual differences in ellagitannin metabolism and host-microbiome interactions.
- Inflammation Research: Exploring its anti-inflammatory potential in various cell and animal models.
Natural Product Chemistry: As a reference standard for the identification and quantification of urolithin isomers in complex biological samples (plasma, urine) and dietary supplements.

3.CLINICAL EFFICACY OF PRODUCT
- Research-Grade Compound: Its availability enables crucial comparative studies. It is detected in human biofluids after ellagitannin consumption, confirming it as a relevant human metabolite.
- Hypothesis-Driven Research: Its unique structure provides a tool to test specific hypotheses, particularly regarding estrogenic activity, that cannot be addressed with Urolithin A or B.
- Preclinical Data Gap: While Urolithins A and B have substantial preclinical data, systematic biological profiling of Urolithin M5 is still in early stages. Its clinical potential remains to be elucidated through targeted in vitro and in vivo studies.
- Foundation for Future Development: Understanding the full spectrum of bioactive urolithins (including M5) is essential for developing precision-nutrition approaches and next-generation postbiotic supplements that account for individual microbiome differences.
