Sustained and Efficient Ethanol Oxidation by Tethering Tunable N‐Donors Onto Integrated MXene/Pd‐Electrodes

Advanced Science, Volume 13, Issue 2, 9 January 2026.
Three novel 3D layered integrated electrodes for Pd‐catalysed ethanol oxidation are developed; their innovative design features N‐heterocyclic amide linkers grafted on an MXene, co‐anchoring Pd nanoparticles via “hand‐in‐hand” coordination. The resulting well‐defined Pd (111) catalytic sites help achieve extremely stable long‐term cycling with ...

Mn2+ Bispidine Complexes as Potential Magnetic Resonance Imaging Agents : Noncoordinating Peripheral Functional Groups Affect Structural, Kinetic, and Relaxation Properties

ChemistryEurope, Volume 4, Issue 1, January 2026.
In the family of Mn2+ complexes formed with pentadentate bispidine chelates, functional groups that do not interfere with metal coordination can play a significant role in enhancing kinetic inertness and proton relaxation efficacy. Mn2+ bispidine complexes combine unprecedented kinetic inertness with high relaxivity and are under scrutiny as potential ...

Carboxylic Solvents and O-Donor Ligand Effects on CH Activation by Pt(II) [PDF]

, 2006
We report on the design of more efficient C−H activation catalysts based on DFT calculations. The first examples of well-defined, N,O-donor ligated platinum complexes that are competent for fast C−H activation are detailed.

Isomerization of α‐Pinene Oxide to Trans‐Pinocarveol

Helvetica Chimica Acta, Volume 109, Issue 1, January 2026.
An operationally simple protocol for the selective isomerization of α‐pinene oxide (APO) to trans‐pinocarveol (TPC) is disclosed, which leverages inexpensive pyridinium‐halide organocatalysts to mitigate competing 1,2‐alkyl shifts. The scalability of this methodology is demonstrated on a decagram scale and catalyst‐recycling is validated through the ...

4-(Dimethylamino)pyridinium tetrachlorido(pyridine-2-carboxylato-κ2N,O)stannate(IV)

Acta Crystallographica Section E, 2012
The reaction of 4-(dimethylamino)pyridine, picolinic acid and stannic chloride yields the title salt, (C7H11N2)[SnCl4(C6H4NO2)], in which the SnIV atom is N,O-chelated by the picolinate ion in a cis-SnNOCl4 octahedral geometry.

Support Vector Machine Identification of Small Molecule Binders to an Understudied Allosteric Site of SARS‐CoV‐2 Mpro for Next‐Generation PROTAC‐Based Therapeutics

Archiv der Pharmazie, Volume 358, Issue 12, December 2025.
An SVM‐based ML model identified 180 potential SARS‐CoV‐2 Mpro inhibitors. MST experiments confirmed three high‐affinity binders, with one showing Kd = 2.8 ± 0.9 μM. These compounds are non‐competitive, suggesting binding to a novel allosteric site.

Highly sensitive analysis of sterol profiles in human serum by LC-ESI-MS/MSs⃞

Journal of Lipid Research, 2008
We have developed a highly sensitive and specific method for the analysis of serum sterol profiles. Sterols in 1 μl of dried serum were derivatized into picolinyl esters (3β-picolinate) and analyzed by liquid chromatography-tandem mass spectrometry (LC ...

Plectranthus‐derived Abietanes as Protein Kinase C‐δ Activators: In Silico Design, Human Serum Albumin Interaction, and Stability Evaluation

Chemistry &Biodiversity, Volume 22, Issue 12, December 2025.
ABSTRACT Cancer remains a major global health challenge. Among protein kinases (PKCs), PKC‐δ acts as a tumor suppressor in colon cancer and represents a valuable therapeutic target. Human serum albumin (HSA) is gaining attention as an efficient drug carrier, while Plectranthus spp. offers a rich source of bioactive compounds.
