EHop-016 is primarily utilized in research settings to study its effects on cancer cell migration and invasion. It functions as a potent inhibitor of Rac GTPase, a protein involved in cell movement and metastasis. By blocking Rac activity, EHop-016 helps researchers understand the mechanisms behind cancer progression and explore potential therapeutic strategies. Its application is particularly relevant in studying breast cancer and other malignancies where Rac signaling plays a critical role. Additionally, it serves as a valuable tool in developing targeted therapies to inhibit tumor spread and improve treatment outcomes.
