Can quercetin reduce arsenic induced toxicity in mouse BALB/c 3T3 fibroblast cells? A study involving in vitro, molecular docking, and ADME predictions

BMC Pharmacology and Toxicology, Journal Year: 2025, Volume and Issue: 26(1)

Published: March 25, 2025

This study aimed to investigate the protective effect of quercetin against arsenic-induced oxidative damage, inflammation, and apoptosis in mouse BALB/c 3T3 fibroblast cells (NIH-3T3). Arsenic at different concentrations 0.05 µM (low), 0.5 (medium), 10 (high) doses were used induce toxicity, while 120 μm was for treatment. MTT LDH analyses performed determine arsenic on cell viability, stress markers antioxidant enzyme activities measured by spectrophotometric method. TNF-α IL-1β levels ELISA method, Autodock programs molecular docking studies. In addition, computer-based succimer molecules using SwissADME web tools. (PDB ID: 2AZ5), 1ITB), Caspase3 2XYG), Bax 4S0O), SOD ID:1CBJ), GSH-Px 1GP1) Bcl-2 1G5M) crystal structures obtained from Protein Data Bank. apoptotic genes mRNA expression Caspase-3 activity QRT-PCR technique. TUNEL staining DNA fragmentations, DAPI done visualise nuclear modifications. Quercetin has been found significantly reduce stress, exert anti-apoptotic effects. Molecular studies revealed shows good binding affinity with SOD, GSH-Px, Bax, Bcl-2, Caspase-3, structures, observed bind scores -7.5 − 7.7 kcal/mol, respectively. These findings are supported results showing that is effective anti-inflammatory processes under vitro conditions. when ADME values examined, it can be considered a useful candidate compound reducing considering its higher synthetic accessibility score, better pharmacokinetic properties, biological transition interaction capacities compared succimer.
