A Three‐Step Route to Functionalized Pyrrole‐2,5‐Dicarboxylic Acids from Galactaric Acid

open access: yesChemSusChem, Volume 19, Issue 8, 28 April 2026.
Galactaric acid (GalA) has been used as substrate for a library of N‐substituted pyrrole‐2,5‐dicarboxylic acids (PDCAs). Existing routes to N‐substituted PDCAs require many steps or lack product isolation. We present a simple, scalable three‐step synthesis from GalA via a 2‐pyrone salt, giving isolated PDCA derivatives in high yield without ...

A Renal Clearable Probe for In Vivo Monoamine Oxidase (MAO) Detection

open access: yesAdvanced Science, Volume 13, Issue 23, 23 April 2026.
A renal‐clearable Cy7‐based fluorogenic probe enables rapid and non‐invasive detection of monoamine oxidase (MAO) activity in vivo. Upon MAO‐mediated activation, the fluorescent product is efficiently excreted in urine, allowing direct quantification of enzyme overexpression.

Aporphine Alkaloids from (Annonaceae)

open access: yesNatural Product Communications, 2008
Guatteria species (Annonaceae) are rich in isoquinoline alkaloids that contain a restricted β-phenethylamine moiety and thus have potential as monoamine oxidase (MAO) inhibitors for the treatment of Alzheimer's and Parkinson's diseases.
