YS-121 is primarily utilized in the field of oncology research due to its potential as an anticancer agent. It has shown promise in inhibiting specific pathways involved in tumor growth and proliferation, making it a candidate for further investigation in targeted cancer therapies. Researchers are particularly interested in its ability to modulate certain proteins or enzymes that play a critical role in cancer cell survival. Additionally, YS-121 is being studied for its potential to enhance the efficacy of existing chemotherapy drugs, potentially reducing the required dosage and minimizing side effects. Its application extends to preclinical studies, where it is used to better understand the mechanisms of cancer progression and to identify new therapeutic strategies.
