FGT-4 

FGT-4 is a folate receptor β (FR-β) targeting chimeric molecule. FGT-4 is a TLR7 agonist. FGT-4 facilitates the secretion of iNOS and proinflammatory cytokine IL-6 associated with M1 macrophages and enhances the proliferation of cytotoxic CD8⁺ T cells. FGT-4 has anti-tumor activity in the 4T1 breast cancer mouse model. FGT-4 can be used for the study of cancer immunity. (Pink: target protein TLR7/8 agonist 1 ligand (HY-103698); black: linker (HY-172936); blue: FR-β ligand (HY-172935))^[1].
