Article Abstract
Enterovirus 71 (EV71), a prominent pathogen associated with hand, foot, and mouth disease (HFMD), has been reported worldwide. To date, the advancement of effective drugs targeting EV71 remains in the preliminary experimental stage. In this study, magnolol demonstrated a significant dose-dependent inhibition of EV71 replication in vitro. It upregulated the overall expression level of nuclear factor erythroid 2 - related factor 2 (Nrf2) and facilitated its nucleus translocation, resulting in the increased expression of various ferroptosis inhibitory genes. This process led to a reduction in reactive oxygen species (ROS) accumulation induced by viral infection. Additionally, magnolol exhibited a broad-spectrum antiviral effect against enteroviruses. Notably, treatment with magnolol substantially enhanced the survival rate of EV71-infected mice, attenuated viral load in heart, liver, brain, and limb tissues, and mitigated tissue inflammation. Taken together, magnolol emerges as a promising candidate for the development of anti-EV71 drugs.

A novel post-modification strategy was developed for rapid functionalization of monoliths through amino-yne click chemistry. This approach enabled the conjugation of activated alkynes onto amino-functionalized organic-silica hybrid monolith surfaces under mild, catalyst-free conditions. Systematic investigation of critical reaction parameters was conducted to optimize the post-modification process.

Ethnopharmacological Relevance: The Shi Pi Zeng Ye Formula (SPZY), a traditional Chinese herbal compound, is empirically used for qi and yin replenishment and has been prescribed for managing functional constipation (FC) comorbid with depression. Although its clinical efficacy is recognized, the active constituents and their precise mechanisms of action in treating FC comorbid with depression have yet to be fully determined.
Aim Of The Study: This research aims to elucidate the efficacy and mechanisms underlying the therapeutic effects of SPZY on FC comorbid with depression, employing a single-arm study design alongside mass spectrometry, network pharmacology, and molecular docking.

Alzheimer disease (AD) is a primary international health dilemma, especially in elderly populations, due to its progressive nature and its adverse cognitive impact. The dysfunction of lysosomes, which impairs protein degradation and leads to toxic accumulation in neurons, is a pivotal factor in AD. We explore phytochemicals that specifically target lysosomal dysfunction via the activation of autophagy, phagocytosis, and lysosome function, exhibiting anti-inflammatory and antioxidant properties.

Alzheimer's disease (AD) is marked by neuroinflammation, neurodegeneration and cognitive decline, with emerging evidence highlighting the critical roles of cytokines and chemokines in its pathogenesis. Regulated cell death is a highly structured and meticulously coordinated series of molecular and signalling processes involving gene expression and protein activity. This mechanism is essential for normal developmental processes and the preservation of tissue homeostasis.

Honokiol (HON) and magnolol (MAG), structural isomers from , exhibit notable anticancer activity, particularly against head and neck squamous cell carcinoma (HNSCC). However, due to their high lipophilicity, their intravenous administration is challenging. This study aimed to develop HON- and MAG-loaded intravenous (IV) nanoemulsions using commercial lipid preparations with varying fatty acid compositions.
