FGT-4

FGT-4 is a FR-β-targeted chimeric molecule. FGT-4 acts as a TLR7 agonist. FGT-4 binds to FR-β to enable delivery to tumor-associated macrophages and myeloid-derived suppressor cells. FGT-4 promotes the secretion of iNOS (associated with M1 macrophages) and the pro-inflammatory cytokine IL-6, and enhances the proliferation of cytotoxic CD8+ T cells. FGT-4 can be used for the research of breast cancer.

In Vitro

FGT-4 (24 h) exhibits minimal cytotoxicity to 4T1 breast cancer cells and HUVEC cells across a broad concentration range^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

FGT-4 (1 mg/kg; i.v.; daily; 14 days) inhibits 4T1 tumor growth, reprograms tumor-associated macrophages to a pro-inflammatory phenotype, reshapes the tumor immune microenvironment, extends mouse survival to 35 days, and exhibits no apparent systemic toxicity^[1].
FGT-4 (20 μg; s.c.; single dose) does not induce elevated pro-inflammatory cytokine levels in healthy mice, demonstrating improved safety compared to free IMDQ^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:

BALB/c (female, 6 weeks old, orthotopic 4T1 tumor model, fed 2-week folate-deficient diet)^[1]
Dosage:

1 mg/kg
Administration:

i.v.; daily; 14 days
Result:

Reduced tumor growth compared to control group, with final tumor weights lower than control.
Increased the M1/M2 macrophage ratio in tumor tissues.
Decreased the proportion of Ly6C⁺ and Ly6G⁺ myeloid-derived suppressor cells within CD45⁺ cells.
Upregulated the percentage of CD8⁺ T cells in tumors.
Extended mouse survival to 35 days.
Caused no significant changes in mouse body weight during treatment.
Detected no pathological alterations in heart, liver, spleen, or kidney tissues.

Dosage:

20 μg
Administration:

s.c.; single dose
Result:

Did not trigger increased plasma levels of TNF-α or IL-6.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
