Medchemexpress LLC Bis(choline)tetrathiomolybdate | 649749-10-0 | 98.0% | 432.56 g/mol | C10H28MoN2O2S4 | 10 MG
ATN-224 (bis(choline)tetrathiomolybdate) is an orally active Cu2+/Zn2+-dependent superoxide dismutase 1 (SOD1) inhibitor used in research to modulate copper-dependent enzymatic activity and angiogenesis. It inhibits SOD1 activity in endothelial and tumor cells and has been characterized in cellular and in vivo models.
- Orally active Cu2+/Zn2+ SOD1 inhibitor with reported IC50 ~17.5 nM in endothelial cells.
- High affinity copper binder, showing selectivity against Ca, Fe, Mg, Zn, and Mn up to 1 mM.
- Inhibits proliferation of HUVEC cells (IC50 ~1.4 μM) and purified SOD1 (IC50 ~0.33 μM after 24 h).
- Time-dependent SOD1 inhibition, reaching maximal effect at ~16 hours.
- Demonstrated inhibition of angiogenesis in Matrigel plug models in mice.
