GR2-128
GR2-128 is a dual inhibitor targeting MLK3 and NAMPT with IC50 values of 84 nM and 14 nM, respectively. GR2-128 inhibits downstream JNK/c‑Jun signaling and reduces NAD+ levels. GR2-128 exhibits antiproliferative and pro-apoptotic activities in triple-negative breast cancer cells without significant toxicity to normal cells. GR2-128 suppresses tumor growth, reduces macrophage and neutrophil infiltration, and increases tumor T-cell markers in a syngeneic mouse model, and can be used for triple-negative breast cancer research.

体外実験
GR2-128 inhibits MLK3 and NAMPT in cell-free enzymatic assays with IC50 values of 84 nM and 14 nM, respectively, and shows weak inhibitory activity against JAK2 (IC50 > 20 µM) [1].
GR2-128 inhibits JNK phosphorylation in MLK3-overexpressing MDA-MB-468 cells with an IC50 of 449 nM [1].
GR2-128 reduces NAD⁺ levels in THP-1 cells with an IC50 of 1.88 nM[1].
GR2-128 (72 h) inhibits the proliferation of multiple breast cancer cell lines, with GI50 values of 0.221 µM and 0.042 µM for MDA-MB-231 and MDA-MB-468 cells, respectively[1].
GR2-128 (48 h) inhibits the proliferation of EO771 cells with a GI50 of approximately 42 nM[1].
GR2-128 (1 µM; 24 h) significantly induces apoptosis in MDA-MB-231 cells, while it does not significantly induce apoptosis in normal IMEC cells[1].
GR2-128 (1 µM) exhibits > 90% inhibition against MLK3, MLK1, PAK4, RET, and TRKA in kinase profiling assays[1].
GR2-128 demonstrates favorable metabolic stability in liver microsomes from both species, with T₁/₂ values of 150 min in mouse and 134 min in human liver microsomes[1].

-
Animal Model:Fmale C57BL/6 mice, 2 × 105 cells/mouse orthotopically implanted in the fourth mammary fat pad [1]
-
Dosage:10 mg/kg
-
Administration:Intraperitoneal injection (i.p.), 5 days a week, for 3 weeks
-
Result:Attenuated tumor growth and reduced tumor burden compared to the vehicle control group.
Decreased tumor cell proliferation, as evidenced by a reduction in Ki67-positive cells.
Induced apoptosis in tumor tissues, as demonstrated by increased levels of cleaved caspase-3 and positive TUNEL staining.
Inhibited MLK3 downstream signaling, showing reduced phosphorylation of MLK3, JNK, and c-Jun in tumor tissues by IHC and Western blot analyses.
Decreased tumor infiltration of macrophages (F4/80⁺) and neutrophils (neutrophil elastase⁺).
Increased tumor infiltration of CD3⁺ T cells and CD8⁺ Granzyme B⁺ cytotoxic T cells, while B cell counts (CD19⁺) remained unchanged.
Did not cause significant histopathological changes in vital organs (lung, liver, heart, and kidney) as assessed by H&E staining.
