1 - (2 - deoxy - 2 - fluoro - β - D - arabinofuranosyl) - 5 - iodouracil, an organic compound, is of great significance in the field of medicinal chemistry. Its chemical structure is based on the backbone of pyrimidine compounds, which is composed of many key parts.
First, look at the uracil part, which is a nitrogen-containing heterocyclic structure and is the core infrastructure of the compound. Uridine is a member of the pyrimidine base family and plays a key role in nucleic acid biosynthesis and metabolism. In 1 - (2 - deoxy - 2 - fluoro - β - D - arabinofuranosyl) - 5 - iodouracil, uracil provides a basic check point and chemical activity center for linking to other groups.
Look at the 2 - deoxy - 2 - fluoro - β - D - arabinofuranosyl moiety, which is specifically modified to be linked to uracil. "2 - deoxy" means that the hydroxyl group on the second carbon atom of the sugar ring is replaced by a hydrogen atom. This structural change has a significant impact on the biological activity and metabolic properties of the compound. " 2-Fluorine "indicates the introduction of fluorine atoms into the second carbon atom of the sugar ring. Fluorine atoms can significantly change the lipophilicity, stability and interaction with biological targets of compounds due to their strong electronegativity and small atomic radius. The configuration of β-D-arabinofuran glycosyl determines the spatial structure and stereochemical characteristics of the whole compound, and is crucial for its binding specificity to receptors or enzymes in organisms.
Finally, there is the 5-iodine part, and the iodine atom is attached to the 5th position of the uracil ring. The large atomic radius and unique electron cloud distribution of iodine atoms endow compounds with special physical and chemical properties, which not only affect their intermolecular forces, but also change the electron cloud density distribution of compounds, which in turn affect their chemical reactivity and biological activity.
In short, the chemical structure of 1- (2-deoxy-2-fluoro - β - D-arabinofuranosyl) -5-iodouracil, through the synergistic action of uracil, modified sugar groups and iodine atoms, exhibits unique physical, chemical and biological activity characteristics, laying the foundation for its application in drug development and other fields.

1 - (2 - deoxy - 2 - fluoro - β - D - arabinofuranosyl) - 5 - iodouracil, often known by its abbreviation FIAU. This drug is mainly used in the field of antiviral, especially in the exploration of anti-hepatitis B virus.
In the past, doctors and pharmacists hoped to use the power of FIAU to overcome the stubborn disease of hepatitis B. The principle is that the substance can mimic natural nucleosides and incorporate them into the replication process of viral DNA, thereby blocking the reproduction of viruses. However, it backfired. In clinical trials, although FIAU showed some antiviral activity, it was accompanied by serious adverse reactions, and many patients suffered from life-threatening conditions such as liver failure.
In view of this serious consequence, FIAU was not widely used in clinical treatment of hepatitis B. Although its antiviral ideas are innovative, safety risks cannot be ignored. Since then, the medical community has also learned from the lessons of FIAU. When developing new drugs, it has been more cautious in safety assessment, and strives to find antiviral drugs with both efficacy and safety.
