Jaskiw, George E. published the artcileSmall phenolic and indolic gut-dependent molecules in the primate central nervous system: levels vs. bioactivity, Category: alcohols-buliding-blocks, the publication is Metabolomics (2022), 18(1), 8, database is CAplus and MEDLINE.
Rapidly growing body of data documents associations between disease of the brain and small mols. generated by gut-microbiota (GMB). While such metabolites can affect brain function through a variety of mechanisms, the most direct action would be on the central nervous system (CNS) itself. Identify indolic and phenolic GMB-dependent small mols. that reach bioactive concentrations in primate CNS. We conducted a PubMed search for metabolomic studies of the primate CNS [brain tissue or cerebrospinal fluid (CSF)] and then selected for phenolic or indolic metabolites that (i) had been quantified, (ii) were GMB-dependent. For each chem. we then conducted a search for studies of bioactivity conducted in vitro in human cells of any kind or in CNS cells from the mouse or rat. 36 metabolites of interests were identified in primate CNS through targeted metabolomics. Quantification was available for 31/36 and in vitro bioactivity for 23/36. The reported CNS range for 8 metabolites 2-(3-hydroxyphenyl)acetic acid, 2-(4-hydroxyphenyl)acetic acid, 3-(3-hydroxyphenyl)propanoic acid, (E)-3-(3,4-dihydroxyphenyl)prop-2-enoic acid [caffeic acid], 3-hydroxybenzoic acid, 4-hydroxybenzoic acid, 2-acetamido-3-(1H-indol-3-yl)propanoic acid [N-acetyltryptophan], 1H-indol-3-yl hydrogen sulfate [indoxyl-3-sulfate] overlapped with a bioactive concentration However, the number and quality of relevant studies of CNS neurochem. as well as of bioactivity were highly limited. Structural isomers, multiple metabolites and potential confounders were inadequately considered. The potential direct bioactivity of GMB-derived indolic and phenolic mols. on primate CNS remains largely unknown. The field requires addnl. strategies to identify and prioritize screening of the most promising small mols. that enter the CNS.
