Amides and formamidines with antinociceptive activity: note II [PDF]

open access: yes, 1993
Forty amides, formamidines and trifluoromethylsulfonylamides bearing on the nitrogen a cyclohexyl residue, eventually 2-substituted, were prepared and tested for analgesic activity against a chemical stimulus.

Advances in Ligand‐Driven Pd‐Catalyzed C─H Functionalizations: Recent Insights and Updates

open access: yesChemCatChem, Volume 17, Issue 15, August 7, 2025.
The most significant advances in ligand‐driven Pd‐catalyzed organic synthesis over the past two years are presented. Processes involving C─H activation of substrates, avoiding their prefunctionalization are illustrated. Both the activity and selectivity of the catalyst depend on the design of the ligands (pyridones, pyridines, amino acids, phosphines ...

Structures of Listeria monocytogenes MenD in ThDP‐bound and in‐crystallo captured intermediate I‐bound forms

open access: yesActa Crystallographica Section F, Volume 81, Issue 8, Page 348-357, August 2025.
Here, we report structures of the ThDP‐dependent enzyme MenD (SEPHCHC synthase) from L. monocytogenes in its ThDP cofactor‐bound and intermediate I‐bound forms. Comparisons with an apo form previously deposited in the PDB revealed that this MenD adopts a typical three‐domain ThDP‐dependent fold, with lower levels of disorder associated with closing of ...

A high‐resolution data set of fatty acid‐binding protein structures. III. Unexpectedly high occurrence of wrong ligands

open access: yesActa Crystallographica Section D, Volume 81, Issue 8, Page 451-464, August 2025.
Very high‐resolution fatty acid‐binding protein structures identified a substantial number of ligands that differ strongly from their expected structure. If different ligand chemistry is a potentially overlooked problem in other, lower resolution, crystal structures of protein–ligand complexes, it has repercussions for any study using such structures ...

Regio‐, Stereoselective, Aerobic and Metal‐Free Synthesis of Z‐Vinyl Sulfides: One‐Pot Hydroiodination of Internal Alkynes and in situ Sulfenylations

open access: yesAdvanced Synthesis &Catalysis, Volume 367, Issue 13, July 23, 2025.
Abstract A novel, metal‐free, air‐ and moisture‐compatible one‐pot tandem protocol for the regio‐ and stereoselective synthesis of Z‐vinyl sulfides (achieving yields up to 99%), is reported. This straightforward and efficient process combines the selective hydroiodination of internal alkynes, promoted by the eutectic mixture choline iodide (ChI)/p‐TsOH

Influence of chirality on the cyclohexene-fused C60 fullerene derivatives as an accepter partner in a photovoltaic cell

open access: yesGreen Energy & Environment, 2016
Organic photovoltaic devices (OPVs) using chiral cyclohexene-fused [C60]-fullerene derivatives that have (l)-menthyl ester moiety have been prepared and their properties evaluated as acceptor molecules with P3HT polymer: racemic cyclohexene-fused [C60 ...
