: The genus is renowned for its diverse bioactive potential, yet the chemical composition and biological properties of remain inadequately explored. This study aimed to investigate the chemical profile, antioxidant capacity, and enzyme inhibitory activities of methanol extracts from various plant parts of . : Methanol extracts were obtained from leaves, stems, flowers, roots, and aerial portions of . The chemical composition was determined using LC-ESI-MS/MS, focusing on key phytochemicals such as hyperoside, kaempferol, 4-hydroxybenzoic acid, and chlorogenic acid. Antioxidant activities were assessed via DPPH, ABTS, and FRAP assays, while enzyme inhibitory activities were evaluated against α-amylase and tyrosinase. In silico molecular docking analyses were conducted to explore the interactions between major compounds and target enzymes. : The leaf extract exhibited the highest total phenolic and flavonoid contents, correlating with superior antioxidant activities, achieving IC values of 16.55 mg/mL, 4.58 mg/mL, and 3.07 mg/mL in DPPH, ABTS, and FRAP assays, respectively. The root extract demonstrated notable α-amylase (IC = 2.99 mg/mL) and tyrosinase (IC = 1.34 mg/mL) inhibitory activities, suggesting potential applications in diabetes and hyperpigmentation management. Molecular docking revealed stable complexes of hyperoside and kaempferol with target enzymes, supporting their roles in observed bioactivities. : This study highlights the bioactivity of extracts, particularly from leaves and roots, supporting their therapeutic potential. Future research should focus on isolating active compounds and conducting in vivo studies to confirm efficacy and elucidate mechanisms of action.

Ethnic fermented foods represent a significant repository for discovering novel probiotic entities. These fermented foods, entrenched in indigenous practices, have conserved a distinct microbiota through generations. Exploration of these fermented foods could yield microbial consortia capable of transforming human health.

LC-HRMS/MS-based molecular-network-guided chemical investigation of led to the isolation of seven undescribed tetrasaccharide-type resin glycosides (-). Their structures were elucidated using 1D and 2D NMR and HRESIMS analysis. Isolated resin glycosides were comprised of d-glucose, d-fucose, d-quinovose, and l-rhamnose, and these monosaccharides were partially acylated with acetyl, isobutyryl, -hexanoyl, and niloyl organic acids.

The mechanisms governing mammalian proton pump V-ATPase function are of fundamental and medical interest. The assembly and disassembly of cytoplasmic V1 domain with the membrane-embedded V0 domain of V-ATPase is a key aspect of V-ATPase localization and function. Here, we show that the mammalian protein ATG16L1, primarily appreciated for its role in canonical autophagy and in noncanonical membrane atg8ylation processes, controls V-ATPase.

Circular RNA (circRNA) has been confirmed to be a regulator for septic acute kidney injury (AKI). It is reported that circ_0049271 has abnormal expression in AKI patients, but its role and mechanism in septic AKI remain unclear. Lipopolysaccharide (LPS)-stimulated HK-2 cells were served as the cellular model of sepsis-associated AKI (SAKI).

This study comprehensively analyses two new ruthenium(III) complexes, [RuCl(Nic)][(CH)NH]DMF, 1, and [RuCl(3-HPA)][3-HHPA](EtOH), 2, (where Nic = nicotinic acid (vitamin B3), 3-HPA = anion of a 3-hydroxypicolinic acid), as potential antimicrobial agents, highlighting their physicochemical properties, nanoparticle formation, and cytotoxic activity. The complexes were fully characterised by a single crystal X-ray diffraction technique, Fourier-transform infrared, energy-dispersive X-ray, and electron paramagnetic resonance spectroscopies. The synthesis of micro- and nanoparticles (NPs) of these complexes was performed using the liquid anti-solvent crystallisation method.
