BBR 2778 dimaleate is primarily used in the field of oncology as an investigational anticancer agent. It functions by interfering with the DNA repair mechanisms in cancer cells, leading to cell death. This compound has shown potential in treating various types of cancers, particularly those that are resistant to other forms of chemotherapy. Its application is often studied in preclinical and clinical trials to evaluate its efficacy and safety in combination with other anticancer drugs. Researchers are particularly interested in its ability to target specific pathways involved in cancer progression, making it a promising candidate for developing targeted cancer therapies.
