The interaction between 5-Bromo-4-thio-2'-deoxyuridine (4-SBrdU) and human serum albumin (HSA) was investigated by the methods of UV-vis absorbance, fluorescence and circular dichroism (CD) spectroscopy and molecular docking under simulative physiological conditions. The results showed that the quenching mechanism of HAS by 4-SBrdU was dynamic fluorescence quenching, hydrophobic interaction was the main intermolecular force based on thermodynamic data, the fluorescence experimental results were in agreement with results obtained by the molecular docking study.

Context: The decline in ovarian reserve is a major concern in female reproductive health, often associated with oxidative stress and mitochondrial dysfunction. Although ginsenoside Rg1 is known to modulate mitophagy, its effectiveness in mitigating ovarian reserve decline remains unclear.
Objective: To investigate the role of ginsenoside Rg1 in promoting mitophagy to preserve ovarian reserve.

Tryptophan catabolism is a central pathway in many cancers, serving to sustain an immunosuppressive microenvironment. The key enzymes involved in this tryptophan metabolism such as indoleamine 2,3-dioxygenase 1 (IDO1) and tryptophan 2,3-dioxygenase (TDO) are reported as promising novel targets in cancer immunotherapy. IDO1 and TDO overexpression in TNBC cells promote resistance to cell death, proliferation, invasion, and metastasis.

Lassa fever (LF), a viral hemorrhagic fever disease with a case fatality rate that can be over 20% among hospitalized LF patients, is endemic to many West African countries. Currently, no vaccines or therapies are specifically licensed to prevent or treat LF, hence the significance of developing therapeutics against the mammarenavirus Lassa virus (LASV), the causative agent of LF. We used in silico docking approaches to investigate the binding affinities of 2015 existing drugs to LASV proteins known to play critical roles in the formation and activity of the virus ribonucleoprotein complex (vRNP) responsible for directing replication and transcription of the viral genome.

This study explores the effects of plant compounds on human papillomavirus (HPV)-induced W12 cervical precancer cells and bioelectric signaling. The aim is to identify effective phytochemicals, both individually and in combination, that can prevent and treat HPV infection and HPV associated cervical cancer. Phytochemicals were tested using growth inhibition, combination, gene expression, RT PCR, and molecular docking assays.

: The proton-coupled amino acid transporter (PAT1) is an intestinal absorptive solute carrier responsible for the oral bioavailability of some GABA-mimetic drug substances such as vigabatrin and gaboxadol. In the present work, we investigate if non-steroidal anti-inflammatory drug substances (NSAIDs) interact with substrate transport via human (h)PAT1. : The transport of substrates via hPAT1 was investigated in Caco-2 cells using radiolabeled substrate uptake and in oocytes injected with , measuring induced currents using the two-electrode voltage clamp technique.
