MedKoo CAT#: 408009

CAS#: 2101317-21-7 (iodide)

Description: S-Gboxin is an active analogue of Gboxin with potent antitumour activity. S-Gboxin inhibits growth of mouse and human glioblastoma (GBM) with an IC50 of 470 nM. Gboxin is an oxidative phosphorylation inhibitor that targets glioblastoma. Gboxin inhibits the growth of primary mouse and human glioblastoma cells but not that of mouse embryonic fibroblasts or neonatal astrocytes. Gboxin rapidly and irreversibly compromises oxygen consumption in glioblastoma cells.

Additional Information

Gboxin relies on its positive charge to associate with mitochondrial oxidative phosphorylation complexes in a manner that is dependent on the proton gradient of the inner mitochondrial membrane, and it inhibits the activity of F0F1 ATP synthase. Gboxin-resistant cells require a functional mitochondrial permeability transition pore that regulates pH and thus impedes the accumulation of Gboxin in the mitochondrial matrix. Administration of a metabolically stable Gboxin analogue inhibits glioblastoma allografts and patient-derived xenografts. Gboxin toxicity extends to established human cancer cell lines of diverse organ origin, and shows that the increased proton gradient and pH in cancer cell mitochondria is a mode of action that can be targeted in the development of antitumour reagents.
