Daily Consumption of Kombucha Influences the Urinary and Plasma Metabolome in a Healthy Human Cohort
Food Science &Nutrition, Volume 13, Issue 10, October 2025.An 8‐week randomized, double‐blind trial tested daily canned kombucha intake (330 mL) in healthy adults. Urinary metabolomics revealed increased polyphenol‐ and fermentation‐related metabolites, while plasma analysis showed reduced acetic acid and slightly lower isoButyric acid.

Indole Synthesis via Allenyl Ester; Enantioselective Total Synthesis of Geissoschizoline
ChemistryEurope, Volume 3, Issue 5, September 18, 2025.An indole synthesis via an allenyl ester intermediate at ambient temperature has been developed. The mild reaction conditions allow the use of a broad range of substrates. Notably, the utility of this approach is demonstrated through the asymmetric total synthesis of geissoschizoline, a Strychnos‐type monoterpenoid indole alkaloid.
