Dualsteric and dual‐acting modulation of muscarinic receptors by antagonist KH‐5

British Journal of Pharmacology, Volume 183, Issue 19, Page 5769-5790, October 2026.
Abstract Background and purpose Muscarinic acetylcholine receptors are key therapeutic targets, and ligands engaging both orthosteric and allosteric sites may offer improved selectivity and efficacy. Here, we investigated whether the muscarinic antagonist KH‐5 acts as a dualsteric antagonist and defined its mode of interaction with muscarinic receptors.

Speciation‐Controlled C–F Bond Functionalization Enabled by Zwitterionic Pnictinidenes

Angewandte Chemie, Volume 138, Issue 39, 21 September 2026.
Zwitterionic pnictinidenes turn C–F activation into C–X bond construction, enabling broad defluorinative functionalization of polyfluoro(hetero)arenes under mild conditions. Rather than following a metallomimetic Sb(I)/Sb(III) redox turnover, catalysis is redirected by ligand scrambling into a redox‐neutral manifold, revealing catalyst speciation as a ...

Serine Octamer Substitution Reactions With α‐Hydroxy Acids

Rapid Communications in Mass Spectrometry, Volume 40, Issue 18, 30 September 2026.
ABSTRACT Rationale The amino acid serine forms chiral magic number clusters, which can be studied using mass spectrometry (MS). Serine octamer clusters are also known to incorporate one or two nonserine monomers with serine monomers to make up the octamer.

Asymmetric Synthesis of Tertiary α‐Aryl Stereocentres in Tetrahydro‐4H‐pyran‐4‐ones Using Pd‐Catalyzed Decarboxylative Asymmetric Protonation

European Journal of Organic Chemistry, Volume 29, Issue 36, 24 September 2026.
The Pd‐catalyzed decarboxylative asymmetric protonation (DAP) has been developed for sterically hindered tetrahydro‐4H‐pyran‐4‐one derived α‐aryl‐β‐keto esters. A substrate scope of nine examples of DAP showed that substrates containing a di‐ortho methoxy substitution pattern on the aryl ring gave rise to the highest enantioselectivities of up to 85 ...

Regioselective Oxidative Oligomerization of 2‐Tert‐Butylpyrene Toward Structurally Defined Oligomers and Their Application in Organic Light‐Emitting Diodes

European Journal of Organic Chemistry, Volume 29, Issue 36, 24 September 2026.
Treatment of 2‐tert‐butylpyrene with Cu2+ afforded structurally well‐defined pyrene oligomers, up to the 13‐mer. Single‐crystal X‐ray diffraction, spectroscopic analyses, and computational studies were conducted to evaluate the properties of the resulting oligopyrenes.
