Belapectin  (Synonyms: GR-MD-02)

Belapectin (GR-MD-02) is a Galectin-3 (Gal-3) inhibitor. Belapectin drives tumor-induced immunosuppression by inducing T cell Apoptosis. Belapectin promotes tumor regression and improves survival of tumor-bearing mice through a CD8+ T cell-dependent mechanism. Belapectin binds to Gal-3 with affinity K_i of 2.8 μM^[1][2].

Belapectin (0.2 mg/mL, 2 mg/mL; 48 h) inhibits the proliferation of 4T1 and MCA-205 cells and induced apoptosis^[1].

Belapectin (2.4 mg/mouse; i.p.; 3 times per week for 3 weeks) only exerts function under the combination with anti-OX40 mAb, does cause a significant reduction in tumor growth and a corresponding increase in survival. The combined treatment also produces lasting long-term memory, and 100 percent of the tumor-free mice were protected from subsequent tumor reattacks^[1].
