Aconitine can interact with the voltage-dependent sodium-ion channels, which are proteins in the cell membranes of excitable tissues, such as cardiac and skeletal muscles and neurons. These proteins are highly selective for sodium ions. They open very quickly to depolarize the cell membrane potential, causing the upstroke of an action potential. Normally, the sodium channels close very rapidly, but the depolarization of the membrane potential causes the opening (activati… WebMechanisms of action of antineoplastic drugs: Alkylating agents: they work by adding an alkyl group to the DNA molecule, preventing the cancer cell from replicating.
