A novel series of histone deacetylases inhibitors (HDACIs) containing benzofuroxan pharmacophore as nitric oxide (NO) donor were designed based on the combination principle and 'multifunctional drugs' theory. As a novel study on embedding NO donor into the structure of HDACIs, all designed hybrid compounds, especially 19d and 24d, displayed remarkable HDACs inhibitory activity and outstanding antiproliferative activity on tumor cells. Besides, they could produce high levels of NO in HCT-116 cells; furthermore, their antiproliferative activity on HCT-116 cells could be diminished by pretreatment with hemoglobin, as the NO scavenger, in a dose-dependent manner. All in all, our designed compounds displayed great inhibitory activities and might offer a prospective avenue to discover novel anti-cancer drugs.

Sleep is crucial for sustaining normal physiological functions, and sleep deprivation has been associated with increased pain sensitivity. The histone deacetylases (HDACs) are known to significantly regulate in regulating neuropathic pain, but their involvement in nociceptive hypersensitivity during sleep deprivation is still not fully understood. Utilizing a modified multi-platform water environment technique to establish a sleep deprivation model.

Article Synopsis
- Epigenetic processes, particularly histone modification by HDACs, are crucial in cancer development, making HDACs important targets for cancer therapies.
- The challenge with most HDAC inhibitors is their non-selective nature and drug resistance, prompting a search for more effective and isoform-selective options.
- Alectinib has been identified through virtual screening as a potential HDAC1 inhibitor with better efficiency and stability, suggesting its promise for therapy in HDAC1-related cancers, pending further validation.
Mechanism of Sirtuin1-Mediated Deacetylation of p65-Mediated Ferroptosis of Hippocampal Neurons in Cerebral Injury after Cardiopulmonary Resuscitation in Rats.

Department of Radiology, the Second Affiliated Hospital of Kunming Medical University, No.374 Yunnan-Burma Road, Wuhua District, Kunming, Yunnan, 650101, PR China.
Objective: Post-resuscitation brain injury is a common sequela after cardiac arrest (CA). Increasing sirtuin1 (SIRT1) has been involved in neuroprotection in oxygen-glucose deprivation (OGD) neurons, and we investigated its mechanism in post-cardiopulmonary resuscitation (CPR) rat brain injury by mediating p65 deacetylation modification to mediate hippocampal neuronal ferroptosis.
Methods: Sprague-Dawley rat CA/CPR model was established and treated with Ad-SIRT1 and Ad-GFP adenovirus vectors, or Erastin.

Background: Alzheimer's Disease (AD) is a prevalent age-related neurodegenerative condition leading to dementia, yet factors regulating its polygenomic etiology and progression remain elusive. MicroRNAs (miRNAs), small RNA molecules regulating protein expression, play a role in neurodegeneration. MicroRNA-34a (miR-34a) is a crucial regulator of numerous genes associated with neurodegenerative disorders, protein aggregation and synaptic transmission genes.

Background: Chemotherapy-induced cognitive impairment (CICI) is a commonly reported neurotoxic side effect of chemotherapy, occurring in up to 75% cancer patients. Connections between chemo-treatment and increased risk of dementia have been reported. Mechanistically, chemotherapy treatment contributes to an accelerated aging phenotype in the brain through induction of pathogenic tau, disruption of neuronal integrity, reactive gliosis and neuroinflammation.
