Article Abstract
is a medicinal plant of the Euphorbiaceae family, which can produce anti-inflammatory and cancer chemopreventive agents of triterpenoids. The present study reports on the bioactive triterpenoids of this plant. Two new lanostane-type triterpenoids, named (3,4,7,9)-4-methyl-3,7-dihydroxy-7(8→9) -lanost-24(28)-en-8-one () and 24-hydroperoxylanost-7,25-dien-3β-ol (), together with 15 known triterpene derivatives, were isolated from . The structures of the new compounds were determined on the basis of extensive spectroscopic data (UV, MS, ¹H and C-NMR, and 2D NMR) analysis. All tetracyclic triterpenoids (⁻) were evaluated for their anti-inflammatory effects in the test of TPA-induced inflammation (1 μg/ear) in mice. The triterpenes exhibited significant anti-inflammatory activities.

Stabilizing the retromer complex rescues synaptic dysfunction and endosomal trafficking deficits in an Alzheimer's disease mouse model.

Disruptions in synaptic transmission and plasticity are early hallmarks of Alzheimer's disease (AD). Endosomal trafficking, mediated by the retromer complex, is essential for intracellular protein sorting, including the regulation of amyloid precursor protein (APP) processing. The VPS35 subunit, a key cargo-recognition component of the retromer, has been implicated in neurodegenerative diseases, with mutations such as L625P linked to early-onset AD.

Background And Purpose: Neuroinflammation is increasingly recognised to contribute to drug-resistant epilepsy. Activation of ATP-gated P2X7 receptors has emerged as an important upstream mechanism, and increased P2X7 receptor expression is present in the seizure focus in rodent models and patients. Pharmacological antagonists of P2X7 receptors attenuate seizures in rodents, but this has not been explored in human neural networks.

Lucilia sericata (Meigen, 1826) maggot excretions/secretions (ES) have demonstrated anti-inflammatory and wound healing potential on corneal epithelial cells. This study aimed to evaluate the in vitro antibacterial potential of the ES against clinically relevant Gram-negative Pseudomonas aeruginosa and Gram-positive Staphylococcus epidermidis in the presence of human tear fluid. The ES was collected from sterile first- and second-instar L.

Objective: Diabetic foot ulcer (DFU) is a common and serious complication of diabetes, often leading to infection, amputation and poor quality of life. Bone marrow mesenchymal stem cells (BMSCs) have shown promise in treating chronic wounds, but their therapeutic efficacy is limited due to poor survival and low regenerative activity. Low-intensity pulsed ultrasound (LIUS), a non-invasive physical modality, has been shown to enhance the biological behavior of BMSCs.

Saikosaponin A (SSa) is an oleanane type triterpenoid saponin isolated from Radix Bupleuri (Bupleurum chinense DC). While SSa has demonstrated significant pharmacological activities including anti-inflammatory, antioxidant, and antidepressant effects, its pharmacokinetic profile remains poorly characterized. This study developed and validated a sensitive LC-MS/MS method for quantifying SSa in rat plasma.
