1.MECHANISM OF ACTION
Urolithin D functions primarily as a competitive and reversible antagonist of Ephrin type-A receptors (EphA), exhibiting intra-class selectivity that allows it to specifically inhibit EphA2 phosphorylation without interfering with EphB receptors. Additionally, it exerts its biological effects through advanced free radical scavenging mechanisms, including formal hydrogen atom transfer (F-HAT) and single electron transfer followed by proton transfer (SET-PT), effectively neutralizing reactive oxygen species like peroxyl and hydroxyl radicals to mitigate oxidative stress at the cellular level.

2.PRODUCT INDICATIONS
This product is indicated for research applications focused on prostate and colon cancer cell migration inhibition, oxidative stress mitigation in neuronal and muscle tissues, and the modulation of inflammatory pathways. It is particularly suitable for scientists and formulators targeting selective EphA receptor signaling in oncology research, as well as for developing supplements aimed at individuals with compromised gut microbiota who are unable to naturally produce sufficient levels of this metabolite from dietary precursors.

3.CLINICAL EFFICACY OF PRODUCT
Preclinical studies demonstrate that Urolithin D effectively reduces oxidative DNA damage by targeting 2-deoxyguanosine lesions and exhibits a high rate constant for quenching peroxyl radicals, suggesting a strong potential for cytoprotection. While human clinical trials are more extensive for Urolithin A, the structural features of Urolithin D confer a unique pharmacokinetic profile with high reactivity, supporting its role in enhancing cellular resilience and supporting mitochondrial function in in vitro and animal models of age-related decline.
