Article Abstract

Eleven undescribed piperidine alkaloids, arecachines A‒J (1-11), were isolated from the peels of Areca catechu. Compounds 8-11 are featured as bis-piperidine alkaloids. Their structures were elucidated by analysis of UV, IR, HRESIMS, 1D and 2D NMR spectra. Compounds 1-4, 6, and 8-11 were evaluated for the monoamine oxidases (MAOs) inhibitory activity. Among them, compounds 3, 4, 6, and 10 showed MAOA inhibitory activity with IC values of 7.85-55.96 μM, while compounds 1-4, 8, 10, and 11 showed MAOB inhibitory activity with IC values of 11.92-77.87 μM.

Macrophage Migration Inhibitory Factor (MIF) is a pleiotropic cytokine that acts as a central regulator of inflammation and immune responses across diverse organ systems. Functioning upstream in immune activation cascades, MIF influences macrophage polarization, T and B cell differentiation, and cytokine expression through CD74, CXCR2/4/7, and downstream signaling via NF-κB, ERK1/2, and PI3K/AKT pathways. This review provides a comprehensive analysis of MIF's mechanistic functions under both physiological and pathological conditions, highlighting its dual role as a protective mediator during acute stress and as a pro-inflammatory amplifier in chronic disease.

Aims: The increasing antimicrobial resistance, particularly in Acinetobacter baumannii, complicates the treatment of infections, leading to higher morbidity, mortality, and economic costs. Herein, we aimed to determine the in vitro antimicrobial, synergistic, and antibiofilm activities of colistin (COL), meropenem, and ciprofloxacin antibiotics, and curcumin, punicalagin, geraniol (GER), and linalool (LIN) plant-active ingredients alone and in combination against 31 multidrug-resistant (MDR) A. baumannii clinical isolates.

Objectives: Bladder cancer is a common malignancy with high incidence and poor prognosis. N-methyladenosine (mA) modification is widely involved in diverse physiological processes, among which the mA recognition protein YTH N-methyladenosine RNA binding protein F2 (YTHDF2) plays a crucial role in bladder cancer progression. This study aims to elucidate the molecular mechanism by which O-linked -acetylglucosamine (O-GlcNAc) modification of YTHDF2 regulates its downstream target, period circadian regulator 1 (), thereby promoting bladder cancer cell proliferation.

Objectives: This study focused on synthesizing and characterizing novel thiosemicarbazide derivatives containing a 1,2,4-triazole moiety and evaluating their antimicrobial activity against several bacterial strains. The research aimed to identify key structural features that enhance antimicrobial efficacy through structure-activity relationship analysis and identify the minimum inhibitory concentration (MIC) of the most potent compounds to assess their potential for further development as antimicrobial agents.

Materials And Methods: Nine novel thiosemicarbazide derivatives containing a 1,2,4-triazole moiety were synthesized by reacting 1,2,4-triazole derivatives with thiosemicarbazide precursors, and the products were characterized using infrared spectroscopy, proton nuclear magnetic resonance (H-NMR), carbon-13 nuclear magnetic resonance (C-NMR) spectroscopy, and elemental analysis.

Sodium-dependent multivitamin transporter (SMVT) is a biotin transporter over-expressed in various types of cancer cells and is commonly studied for targeted drug delivery using biotin conjugates. However, such conjugates lack the carboxyl group needed for recognition by SMVT. Previously, we proposed that SMVT is unlikely the transporter of biotin conjugates.
