How are oxetanes being studied for antiviral and anticancer uses?

Oxetanes are four-membered rings containing one oxygen atom. In the context of medicinal chemistry, researchers are actively investigating numerous synthetic oxetanes as potential therapeutic agents.1

These compounds are being studied as analogs of oxetanocin, a natural product known for its antiviral properties. Beyond their potential as antiviral agents, these synthetic oxetane derivatives are under investigation for their efficacy as anticancer, anti-inflammatory, and antifungal agents. While oxetanes are distinct from the well-known $\beta$-lactam antibiotics—which feature a four-membered azetidinone ring—the ongoing research into oxetanes highlights the importance of small, strained heterocyclic rings in the development of new pharmaceutical treatments.1
