Discovery of a Potent and Selective MAO‐B Inhibitor From a Donepezil‐Linked Chalcone Library With Promising Antiparkinsonian Activity

open access: yesDrug Development Research, Volume 87, Issue 5, August 2026.
ABSTRACT A focused library of 19 donepezil‐linked chalcones (DLCs) was efficiently synthesised through microwave‐assisted Claisen‐Schmidt condensation and subsequently profiled for their inhibitory activities against cholinesterases (AChE and BuChE) as well as monoamine oxidases (MAO‐A and MAO‐B).

Von Richter Cinnolines Synthesis Revisited—Approach to Polysubstituted Cinnoline Derivatives as Important Scaffolds for Kinase Inhibitors

open access: yesChemistrySelect, Volume 11, Issue 29, 3 August 2026.
A revised von Richter cyclization of 2‐aminoalkyne precursors enables the synthesis of polysubstituted 4‐halocinnoline derivatives. By addressing the key challenge of hydrolytic instability, this catalyst‐free approach delivers scaffolds amenable to late‐stage C‐4 functionalization.
