Newly synthesized benzimidazole hydrazone derivatives 1-26 were evaluated for their α-glucosidase inhibitory activity. Compounds 1-26 exhibited varying degrees of yeast α-glucosidase inhibitory activity with IC50 values between 8.40 ± 0.76 and 179.71 ± 1.11 μM when compared with standard acarbose. In this assay, seven compounds that showed highest inhibitory effects than the rest of benzimidazole series were identified. All the synthesized compounds were characterized by different spectroscopic methods adequately. We further evaluated the interaction of the active compounds with enzyme with the help of docking studies.

Exploration of cognitive flexibility and emotion recognition in adolescents with eating disorders.
J Int Neuropsychol Soc
January 2025
Department of Psychiatry, Ankara University, Ankara, Turkey.
Objectives: This study compared cognitive flexibility (CF) and emotion recognition (ER) in adolescents with eating disorders (ED) to a healthy group.
Methods: Forty healthy individuals aged 12-18 years with no psychiatric diagnosis and 46 patients diagnosed with anorexia nervosa (AN), bulimia nervosa (BN), or binge eating disorder (BED) according to DSM-5 criteria participated. CF was assessed using the Cognitive Flexibility Scale (CFS), Stroop Test, and Berg Card Sorting Test (BCST), while ER was evaluated using the test of perception of affect via nonverbal cues.
λ-cyhalothrin induced sex-specific inflammation, glia activation and GABAergic interneuron disruption in the hippocampus of rats.

Department of Anatomy, College of Health Sciences, University of Ilorin, Ilorin, 240003, Nigeria.
Background: Glia mediated neuroinflammation and degeneration of inhibitory GABAergic interneurons are some of the hall marks of pyrethroid neurotoxicity. Here we investigated the sex specific responses of inflammatory cytokines, microglia, astrocyte and parvalbumin positive inhibitory GABAergic interneurons to λ-cyhalothrin (LCT) exposures in rats.
Methods: Equal numbers of male and female rats were given oral corn oil, 2 mg/kg.
6-thioguanine inhibits EV71 replication by reducing BIRC3-mediated autophagy.
BMC Microbiol
January 2025
Center for Public Health Research, Medical School of Nanjing University, Nanjing, China.
Background: Enterovirus 71 (EV71) is one of the major causative agents of hand, foot, and mouth disease (HFMD), and can cause severe cerebral complications and even fatality in children younger than 5 years old. However, there is no specific medication for EV71 infection in clinical practice. Our previous studies had identified the 6-thioguanine (6-TG), an FDA-approved anticancer drug, as a potential antiviral agent, but its anti-EV71 activity is largely unknown, therefore, we aim to explore the antiviral effect of 6-TG on EV71.

Background: Macrophages play an important role in the pathogenesis of ulcerative colitis (UC). We will explore the effects of sodium butyrate (SB) on macrophage function.
Methods: The targets of butyric acid were identified using SwissTargetPrediction database and surface plasmon resonance (SPR).
Downmodulation of potassium conductances induces epileptic seizures in cortical network models via multiple synergistic factors.
J Neurosci
January 2025
Department of Neuroscience, Brown University, Providence RI, USA.
Voltage-gated potassium conductances [Formula: see text] play a critical role not only in normal neural function, but also in many neurological disorders and related therapeutic interventions. In particular, in an important animal model of epileptic seizures, 4-aminopyridine (4-AP) administration is thought to induce seizures by reducing [Formula: see text] in cortex and other brain areas. Interestingly, 4-AP has also been useful in the treatment of neurological disorders such as multiple sclerosis (MS) and spinal cord injury, where it is thought to improve action potential propagation in axonal fibers.
