KLF7 Blocks MKNK2/HIF‐1 Pathway‐Mediated M1 Microglia Polarization to Ameliorate Ischemic Stroke‐Induced Neurological Injury

open access: yesBrain and Behavior, Volume 15, Issue 9, September 2025.
Schematic diagram. Low KLF7 expression after IS further impairs transcriptional repression of MKNK2, which exacerbates MCAO/R‐induced pathological injury in mice by activating the HIF‐1 pathway‐mediated pro‐inflammatory M1 polarization of microglia. ABSTRACT Background Ischemic stroke (IS) is a common neurological disease with a significant financial ...

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 ...

3-Alkoxy-1-Benzyl-5-Nitroindazole Derivatives Are Potent Antileishmanial Compounds [PDF]

open access: yes
Indazoles have previously been identified as molecules with antiprotozoal activity. In this study, we evaluate the in vitro activity of thirteen 3-alkoxy-1-benzyl-5-nitroindazole derivatives (series D) against L. amazonensis, L. infantum, and L. mexicana.

Unexpected Tellurohalogenation of Terminal N‐Alkynyl (Alkenyl) Derivatives of 4‐Functionalized Pyrazoles

open access: yesChemistryOpen, Volume 14, Issue 8, August 2025.
New tellurium‐containing tetrahydropyrazolo[1,2‐a]pyridazines and dihydropyrazolo[1,2‐a]pyrazoles were obtained by electrophilic heterocyclization in the form of intramolecular salts, and optimal conditions for their synthesis were found. The heterocyclization process is regio‐ and stereoselective, which is confirmed by spectral studies, and by X‐ray ...

Multidirectional Synthesis of Substituted Indazoles via Iridium-Catalyzed C–H Borylation [PDF]

open access: yes, 2015
In the absence of a steric directing group, iridium-catalyzed C–H borylation of N-protected indazoles occurs rapidly and selectively at C-3 and the resulting boronate esters can be utilized in a range of downstream conversions.

C−H Alkylation of Heterocycles via Light‐Mediated Palladium Catalysis

open access: yesAngewandte Chemie, Volume 137, Issue 4, January 21, 2025.
The photoexcitation of palladium catalysts enables the C−H functionalization of aromatic heterocycles with alkyl halides via a radical strategy. By integrating experimental and computational approaches, we develop a predictive substrate scope and outline generalized synthetic applications. Abstract Methods enabling direct C−H alkylation of heterocycles

eAmidation: An Electrochemical Amidation of Aldehydes via the Oxidation of N‐Aryl Hydrazones

open access: yesAdvanced Synthesis &Catalysis, Volume 367, Issue 14, July 29, 2025.
The indirect electrochemical oxidation of N‐aryl hydrazones offers an efficient approach to access amides from aldehydes and amines. The AZADO‐mediated reaction enables the selective synthesis of a broad range of valuable amides using readily available aldehydes.
