Salinomycin is widely used in the poultry industry as an anticoccidial agent, effectively controlling coccidiosis, a parasitic disease that affects the intestinal tract of birds. It promotes growth and improves feed efficiency in livestock by targeting harmful protozoa. Additionally, research has explored its potential as an anticancer agent, particularly in targeting cancer stem cells, which are often resistant to conventional therapies. Its ability to selectively induce apoptosis in these cells has shown promise in preclinical studies for various cancers, including breast, lung, and colorectal cancer. Salinomycin is also investigated for its antimicrobial properties, particularly against drug-resistant bacteria, making it a candidate for combating antibiotic resistance.
