BCI-121 is primarily used in research and development within the field of oncology. It serves as a potential therapeutic agent for cancer treatment, particularly in targeting specific molecular pathways involved in tumor growth and progression. Researchers utilize BCI-121 to study its efficacy in inhibiting cancer cell proliferation and inducing apoptosis in preclinical models. Its application extends to exploring its potential as a chemotherapeutic drug, either alone or in combination with other treatments, to enhance anti-cancer effects. Additionally, BCI-121 is investigated for its role in overcoming drug resistance in certain cancers, making it a valuable tool in advancing cancer therapy research.
