Thalidomide-5,6-F is primarily used in research and development within the field of medicinal chemistry. Its applications are focused on studying its potential as a therapeutic agent, particularly in the treatment of certain cancers and inflammatory diseases. The compound is investigated for its ability to modulate the immune system and inhibit angiogenesis, which is the process of new blood vessel formation that can support tumor growth. Additionally, it is explored for its role in targeting specific cellular pathways involved in disease progression. Researchers also utilize it to understand structure-activity relationships, aiming to design more effective and safer derivatives for clinical use. Note: This is a research chemical and not approved for clinical use; handle with care due to potential teratogenic effects similar to thalidomide.
