Aims:
Oncology treatments aim at selective toxicity for tumor (compared to normal) cells, and chromone- coumarin hybrids have shown such activity.
Methods:
In this study, we test a novel series of synthetic chromone and coumarin derivatives (1-9) for cytotoxic activity against a panel of tumor cell lines (MCF-7, A549, HepG2, HTC-116, B16 and Caco-2) opposed to non-tumor cells (HEK-293t). Electrical impedance spectroscopy was used to monitor cell viability in real time.
Results:
Compound 8 showed the most potent activity, and it significantly diminished cancer cell proliferation and viability in different cell lines. It induced apoptosis in a dose-dependent manner, as shown by Western blot and flow cytometry.
Conclusion:
Electrical impedance spectroscopy appears to be a convenient tool for in vitro cytotoxicity analysis, which could be useful for identifying drug effects and side effects during early phases of drug discovery and development.

Impedances and Admittance
Impedance is a measure of resistance to sinusoidal current flow in an AC circuit. Unlike their behavior in DC circuits, where inductors appear as short circuits and capacitors as open circuits, the behavior of these components in AC...

Series Impedances: Three-Phase Line
Using Kirchhoff's laws, an integro-differential equation for the network is derived. This equation accounts for unbalanced phase currents, which may induce return currents through neutral wires and the earth, seeking the least impedance path. Earth return conductors can replace the...
