The conversion of nitro(hetero)arenes to corresponding (hetero)aryl amines and other practical organic compounds plays a crucial role in various sciences, especially environmental remediation and public health. In the current research work, diverse green and efficient strategies for the convenient reduction (hydrogenation) and one-pot two-step reductive acetylation of nitro(hetero)arenes using a core-shell-type mesoporous zirconocene-containing magnetically recoverable nanocomposite ( FeO@APTMS@CpZrCl ) as a powerful nanocatalytic system have been developed. In the presented organic transformations, the superparamagnetic FeO@APTMS@CpZrCl nanocomposite exhibited satisfactory turnover numbers (TONs) and turnover frequencies (TOFs), along with acceptable reusability. On the other hand, we investigated the potential biological effect of the synthesized (hetero)aryl amines and -(hetero)aryl acetamides against the transmembrane domain (TMD) of the human -methyl-d-aspartate (NMDA) receptor based on molecular docking studies. Furthermore, the drug-likeness properties of our hit compound (-(3-(1-hydroxyethyl)phenyl)acetamide) have been scrutinized by ADMET analyses.

Long-term potentiation (LTP) is proposed to be the molecular mechanism underlying learning and memory in the brain. A key event for LTP is the influx of calcium into post-synaptic neurons via multiple ion channel control systems. One such system involves N-methyl-D-aspartate receptors (NMDARs), which were originally believed to be essential for LTP and new learning.

Alzheimer's disease (AD) is a severe neurodegenerative disease characterized mainly by the formation of amyloid beta (Aβ) plaques and abnormal phosphorylation of tau. In recent years, an imbalance in iron homeostasis has been recognized to play a key role in the pathological process of AD. Abnormal iron accumulation can activate various kinases such as glycogen synthase kinase-3β, cyclin-dependent kinase 5, and mitogen-activated protein kinase, leading to abnormal phosphorylation of tau and amyloid precursor protein, and accelerating the formation of Aβ plaques and neurofibrillary tangles.

The GluN1/GluN3A receptor, a unique excitatory glycine receptor recently identified in the central nervous system, challenges traditional perspectives of N-methyl-D-aspartate (NMDA) receptor diversity and glycinergic signaling. Its role in emotional regulation positions it as a potential therapeutic target for neuropsychiatric disorders. However, pharmacological research on GluN1/GluN3A receptors remains at an early stage.

After decades of limited progress in depression treatment, recent advancements have sparked renewed interest in developing novel antidepressants, particularly rapid-acting antidepressants (RAADs). Despite these promising developments, there remains a significant gap in research on bipolar depression. While several antipsychotics have been investigated for their efficacy in bipolar depression due to the reduced risk of mania induction, research on RAADs, such as (es)ketamine, remains scarce despite their demonstrated safety and effectiveness.

Postinfectious, diarrhea-predominant, irritable bowel syndrome (PI-IBS-D) is difficult to treat owing to its unknown pathophysiology. Extracellular vesicles (EVs) derived from human colon tissue and long noncoding RNAs (lncRNAs), such as growth arrest-specific 5 (GAS5), may play key roles in the pathophysiology of PI-IBS-D. To determine whether altered colonic EV lncRNA signaling leads to gastrointestinal dysfunction and heightened visceral nociception in patients with PI-IBS-D via the GAS5/miR-23ab/NMDA NR2B axis, we conducted translational studies, including those on (a) the role of colonic EV lncRNAs in patients with PI-IBS-D, human colonoids, and PI-IBS-D tissues; (b) i.
