Used in targeted cancer therapy, particularly for tumors overexpressing the RON receptor such as in certain breast, pancreatic, and gastric cancers. It functions by blocking RON signaling pathways, inhibiting tumor cell proliferation, migration, and survival. Also employed in research settings to study RON receptor function and as a reference standard in immunoassays and antibody development. Shows potential in combination therapies with other oncology agents to enhance antitumor efficacy.
