Figure 4From: Mitigating prolonged QT interval in cancer nanodrug development for accelerated clinical translationhERG tail current density averages obtained by measuring the hERG tail peak amplitude at 20 mV in baseline conditions and in the presence of curcumin, Formulation HNC-NP, Formulation HNC-PS and Formulation HNC-PS-C hybrid nanocurcumin. The curcumin concentrations were always 6.0, 12 and 18 μM. A: Current density was measured from 7 cells, averaged, normalized against baseline current density, and corrected for time and solvent effects. Statistical comparisons between post-drug exposure and baseline current density levels were made using repeat paired Student’s t-tests (*). Differences were considered significant when p ≤ 0.05. B: Voltage dependency of the hERG tail currents inhibition at the higher concentration of curcumin and hybrid nanoformulations tested (18 μM).Back to article page
