Total Syntheses of Sappanin-Based Natural Products Enabled by Pattern Recognition Analysis and Brominative Aromatization. [PDF]

open access: yesChem Asian J
A unified synthetic strategy enables the total syntheses of sappanin‐based natural products from a common privileged intermediate derived from cyclic vinylogous esters. Abstract Described is a concise route to caesappins A and B, urolithin C, and protosappanin A, which share a common sappanin core.

Urolithins: A Prospective Alternative against Brain Aging

open access: yesNutrients, 2023
The impact of host–microbiome interactions on cognitive health and disease has received increasing attention. Microbial-derived metabolites produced in the gut are one of crucial mechanisms of the gut–brain axis interaction, showing attractive perspectives. Urolithins (Uros) are gut microbial-derived metabolites of ellagitannins and ellagic acid, whose

A Novel Streptococcus thermophilus FUA329 Isolated from Human Breast Milk Capable of Producing Urolithin A from Ellagic Acid

open access: yesFoods, 2022
Urolithin A, a metabolite of ellagic acid, has many beneficial biological activities for people. Strains capable of producing urolithin A from ellagic acid have the hope of becoming the next-generation probiotics.

Urolithin A alleviates neuropathic pain and activates mitophagy

open access: yesMolecular Pain, 2023
Neuropathic pain (NP) occurs frequently in the general population and has a negative impact on the quality of life. There is no effective therapy available yet owing to the complex pathophysiology of NP. In our previous study, we found that urolithin A (UA), a naturally occurring microflora-derived metabolite, could relieve NP in mice by inhibiting ...

NMR Spectroscopic Identification of Urolithin G, a Novel Trihydroxy Urolithin Produced by Human Intestinal Enterocloster Species

open access: yesJournal of Agricultural and Food Chemistry, 2023
Urolithins are gut microbiota metabolites of ellagic acid. Here, we have identified and chemically characterized a novel urolithin produced from urolithin D (3,4,8,9-tetrahydroxy urolithin) by in vitro incubation with different human gut Enterocloster species under anaerobic conditions. Urolithin G (3,4,8-trihydroxy urolithin) was identified by 1H NMR,

Ellagic acid and its fermentative derivative urolithin A show reverse effects on the gp91-phox gene expression, resulting in opposite alterations in all-trans retinoic acid-induced superoxide generating activity of U937 cells

open access: yesBiochemistry and Biophysics Reports, 2021
Ellagitannins (esters composed of glucose and ellagic acid) are hydrolyzed to generate ellagic acid in gut followed by conversion of ellagic acid to urolithins such as urolithin A by intestinal bacteria.

Urolithin M5 from the Leaves of Canarium album (Lour.) DC. Inhibits Influenza Virus by Targeting Neuraminidase

open access: yesMolecules, 2022
Ganlanye (GLY), the leaf of Canarium album (Lour.) DC., is a traditional Chinese medicinal herb for warm disease treatment. We found that its aqueous extract could inhibit the influenza A virus.

A Combination Therapy of Urolithin A+EGCG Has Stronger Protective Effects than Single Drug Urolithin A in a Humanized Amyloid Beta Knockin Mice for Late-Onset Alzheimer’s Disease

open access: yesCells, 2022
In the current study, for the first time, we study mitophagy enhancer urolithin A and a combination of urolithin A+green tea extract EGCG against human Aβ peptide-induced mitochondrial and synaptic, dendritic, inflammatory toxicities and behavioral ...

An in vitro investigation of the effects of urolithins A and B on low-density lipoprotein uptake and its regulatory genes

open access: yesArchives of Medical Science, 2023
Introduction This study aimed to evaluate the possible role of urolithin A (UA) and urolithin B (UB) on the mRNA expression levels of LDL receptor (LDLR) and PSCK9 genes, and also of the uptake of LDL particles in HepG2 cells.

Mitophagy Activation by Urolithin A to Target Muscle Aging

open access: yesCalcified Tissue International, 2023
AbstractThe age-related loss of skeletal muscle function starts from midlife and if left unaddressed can lead to an impaired quality of life. A growing body of evidence indicates that mitochondrial dysfunction is causally involved with muscle aging. Muscles are tissues with high metabolic requirements, and contain rich mitochondria supply to support ...
