VB124 is an orally active, potent, and selective monocarboxylate transporter 4 (MCT4) inhibitor used in research to block lactate import and export. It exhibits low-nanomolar cellular activity (IC50 = 8.6 nM for import, 19 nM for export in MDA-MB-231 cells) and is applied in studies of cancer metabolism, cardiac hypertrophy, and heart failure.
- Selective MCT4 inhibition.
- Low-nanomolar potency in cellular assays.
- Redirects glycolytic carbon flux toward mitochondria.
- Available as solid and DMSO solution formulations.
- Recommended storage for powder and solvent formulations.
- High reported purity (~98.9%).
