Arabinofuranosyluracil serves as a critical reference standard in virology research, particularly for studying herpes simplex virus (HSV) inhibition mechanisms. It acts as a competitive substrate for viral thymidine kinase, enabling targeted disruption of viral DNA synthesis. In oncology, Ara-U has demonstrated antiproliferative effects in lymphoma studies by interfering with nucleotide salvage pathways. Researchers also utilize this compound to investigate nucleoside transport systems and metabolic resistance in genetically modified cell lines.
