Dibenzofuran

Dibenzofuran (CAS No.: 132-64-9) is a heterocyclic organic compound widely utilized as a biochemical research reagent in life sciences, characterized by a fused aromatic framework that supports diverse interactions with biological macromolecules. It has been reported to modulate specific signaling pathways and enzymatic activities, thereby influencing cellular and molecular processes relevant to disease mechanism studies. Notably, Dibenzofuran has demonstrated inhibitory activity toward the aryl hydrocarbon receptor, a ligand-activated transcription factor involved in xenobiotic metabolism and immune regulation, and has also shown antiviral effects in experimental systems such as bovine viral diarrhoea virus models, suggesting its utility in probing host–pathogen interactions. Its bioactivity is generally observed across nanomolar to micromolar concentration ranges depending on the assay system and target context. As a small-molecule tool compound, Dibenzofuran is commonly applied in in vitro cell-based assays and biochemical studies to investigate receptor-mediated signaling, enzyme modulation, and pathway-specific responses, and may also be incorporated into broader screening platforms for compound library evaluation. Experimental concentrations and conditions should be optimized according to specific study designs, making it a versatile component in mechanistic research and early-stage discovery efforts.
