| Description |
VGSC blocker-1 is a potent and small molecule blocker of neonatal isoform of the VGSC subtype, Nav1.5 (nNav1.5). VGSC blocker-1 blocks INa peak currents 34.9% at 1 μM and inhibits cell invasion 0.3% at 1 μM in human breast cancer cell line MDA-MB-231, without affecting the cell viability[1].

| In Vitro |
VGSC blocker 1 (1.0 to 10μM) inhibits human breast cancer cell line MDA-MB-231[1]. Cell Viability Assay[1] Cell Line: human breast cancer cell line MDA-MB-231 Concentration: 1.0 to 10μM Incubation Time: 24 hours Result: VGSC blocker 1 blocks INa peak currents 34.9% at 1 uMa and inhibits cell invasion 0.3% at 1 uM. These values are much higher than the concentrations required (0.1 μM and 1 μM) to produce significant nNav1.5 current blockade and cell invasion inhibition.
