From farm to pharma: Investigation of the therapeutic potential of the dietary plants Apium graveolens L., Coriandrum sativum, and Mentha longifolia, as AhR modulators for Immunotherapy.

ABSTRACT

Autoimmune diseases represent a complex array of conditions where the body's immune system mistakenly attacks its own tissues. These disorders, affecting millions worldwide, encompass a broad spectrum of conditions ranging from rheumatoid arthritis and multiple sclerosis to lupus and type 1 diabetes. The Aryl hydrocarbon receptor (AhR) translocator, expressed across immune and other cell types, plays crucial roles in immune disorders and inflammatory diseases. With a realm towards natural remedies in modern medicine for disease prevention, this study investigates the electronic properties and behaviors of bioactive compounds from dietary sources, including Apium graveolens L. (Celery), Coriandrum sativum seeds (Coriander), and Mentha longifolia, as AhR modulators. Through comprehensive analysis (HOMO-LUMO, ESP, LOL, and ELF), electron-rich and -poor regions, electron localization, and delocalization are identified, contrasting these compounds with the toxic AhR ligand, TCDD. Evaluation of Absorption, Distribution, Metabolism, Excretion, and Toxicity (ADMET) properties reveals favorable pharmacokinetics without blood-brain barrier penetration, indicating drug-like characteristics. Molecular docking demonstrates stronger interactions of dietary flavonoid ligands with AhR transcription compared to TCDD. Molecular dynamics simulations confirm the stability of complexes and the sustainability of interactions formed. This research underscores the potential of natural compounds as effective AhR modulators for therapeutic interventions in immune-related disorders.
