Fe‐Photocatalyzed Decarboxylative Giese‐Type Reaction of α‐N, O or S Carboxylic Acids: Insight into the Mechanism of the Radical Formation

Advanced Synthesis &Catalysis, EarlyView.
Electron‐deficient alkenes can be functionalized with α‐amino, α‐alkoxy and α‐alkylthio radicals formed by Fe‐photocatalyzed decarboxylation of the corresponding carboxylic acids. The reactions proceed under smooth ligandless conditions with inexpensive base and in the absence of oxidant. A mechanistic computational TD‐DFT study supports the occurrence

Clinical relevance of depressed kynurenine pathway in episodic migraine patients: potential prognostic markers in the peripheral plasma during the interictal period

The Journal of Headache and Pain, 2021
Background Altered glutamatergic neurotransmission and neuropeptide levels play a central role in migraine pathomechanism. Previously, we confirmed that kynurenic acid, an endogenous glutamatergic antagonist, was able to decrease the expression of ...

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

Advanced Science, EarlyView.
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 ...

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

Chemistry &Biodiversity, EarlyView.
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.

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

ChemistryEurope, EarlyView.
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 ...
