Thalidomide-4-O-C10-COOH is primarily utilized in research focused on developing targeted drug delivery systems. Its structure allows it to be conjugated with other molecules, making it valuable in creating prodrugs that can selectively release active compounds in specific tissues or cells. This property is particularly useful in cancer therapy, where it can help minimize side effects by delivering drugs directly to tumor sites. Additionally, its modified structure enables it to interact with biological pathways involved in inflammation and angiogenesis. This makes it a candidate for studying diseases characterized by abnormal blood vessel formation, such as certain cancers and macular degeneration. Researchers also explore its potential in modulating immune responses, which could lead to applications in autoimmune disorders or transplant rejection. In summary, Thalidomide-4-O-C10-COOH serves as a versatile tool in drug development, particularly in targeted therapies and research into angiogenesis and immune modulation.
