Abstract <p>The chemical structures of a number of natural and synthetic drugs contain the 1,3-dioxolane ring (DR). According to various developing structure–activity relationships, the presence of this heterocyclic ring can improve different types of biological activity. These include anticancer, antifungal, antiviral, antibacterial, antioxidant, and anti-inflammatory properties. The contemporary problem of adverse medication reactions and resistance necessitates the development of potent agents with innovative structures to address these therapeutic challenges. The goal of this review is to highlight the activity-enhancing effect of the DR in the chemical frameworks of various bioactive conjugates. We have compiled data from various scientific platforms, including PubMed, Google Scholar, Scopus, and Web of Science, without limitations on the publication date. The unique biomedical efficacy of DR-containing conjugates motivates further studies in this area, as incorporating DR into the chemical framework enhances diverse biological activities. Numerous research studies suggest that the presence of two oxygen atoms in the DR backbone contributes to the enhanced effect of the studied ring. The hydrogen bonding between these oxygen atoms and the intended active site is responsible for the improved ligand-target interactions and increased biological activity resulting from DR incorporation.</p>
