MG-T-19
Based on 1 Customer Validation
MG-T-19 is a potent small-molecule inhibitor targeting human TIM-3. MG-T-19 blocks the interactions between TIM-3 and its ligands such as phosphatidylserine, CEACAM1 and Galectin-9. MG-T-19 promotes the secretion of TNF-α and IFN-γ by peripheral blood mononuclear cells, and significantly enhances their ability to inhibit cancer cell proliferation. MG-T-19 can be used in studies related to acute myeloid leukemia.

Biological Activity
MG-T-19 (2.5 μM) significantly inhibits the interactions of human TIM-3 with PtdSer, CEACAM1, and Gal-9 in cell-free and cell-based ligand binding assays[1].
MG-T-19 (2.5 μM; 48 h) pretreatment of healthy donor PBMCs increases TNF-α and IFN-γ production following stimulation[1].
MG-T-19 (2.5 μM; 6 days) incubation of Kasumi-1 acute myelogenous leukemia cells with healthy donor PBMCs significantly reduces Kasumi-1 cell proliferation[1].
MG-T-19 binds to purified human TIM-3 with a Kd of 0.26 μM and inhibits TIM-3 interactions with its ligands PtdSer, CEACAM-1, and galectin-9[2].
MG-T-19 enhances TNF-α and IFN-γ secretion by healthy donor peripheral blood mononuclear cells and boosts inhibition of Kasumi-1 cell proliferation[2].

-
Cell Line:Kasumi-1 acute myelogenous leukemia cells, peripheral blood mononuclear cells (PBMCs) from healthy donors
-
Concentration:2.5 μM
-
Incubation Time:6 days; 16 h (H3 thymidine labeling)
-
Result:Augmented the capacity of PBMCs to impede the proliferation of Kasumi-1 cells, resulting in significantly reduced H3 thymidine uptake compared to coculture controls.
