Our previous studies revealed that iptakalim, a novel ATP-sensitive potassium channel opener, has a significant neuroprotective function against ischemia in vivo or rotenone-induced neurotoxicity in vitro.

In vitro cell studies have shown that rotenone-induced toxicity is reduced by the use of N-acetylcysteine, antioxidants and potassium channel openers.

In the present study, we demonstrated that systematic administration with iptakalim (IPT), an adenosine triphosphate (ATP)-sensitive potassium channel (K (ATP)) opener, could alleviate rotenone-induced degeneration of dopaminergic neurons in rat substantia nigra along with the downregulation of microglial activation and mRNA levels of tumor necrosis factor-alpha (TNF-alpha) and cyclooxygenase-2 (COX-2).

The mitochondria appeared to be the source of the NOX-dependent ROS released by the "ROS-induced ROS release mechanism" that was blunted by the mitochondrial ATP-sensitive potassium channel blockers 5-hydroxydecanoate and glibenclamide, inhibition of complex I of the electron transport chain with rotenone, and inhibition of the permeability transition pore (MPTP) by cyclosporin A.

The aim of the present study is to examine the potential therapeutic effects of iptakalim, an ATP-sensitive potassium-channel opener, and diazoxide, a selective mitochondrial ATP-sensitive potassium-channel opener, on Parkinsonian symptoms in rats induced by rotenone.

In the present study, the neuroprotective effect of iptakalim, a novel ATP-sensitive potassium channel opener, was studied against rotenone-induced cytotoxicity in rat dopaminergic PC12 cells.

We measured the ability of mitochondrial inhibitors of complexes I (rotenone, MPP (+), and HPP (+)), II (amdro), IV (Na cyanide), and an uncoupler (dinoseb) to release preloaded dopamine from murine striatal synaptosomes.

The degree of protection is in proportion to the bouts of exposure to an ATP-sensitive potassium channel opener, a feature reminiscent of ischemic tolerance in vivo.

Durum wheat mitochondria may act against chloroplast/cytosol over-reduction: the malate/oxaloacetate antiporter and the rotenone-insensitive external NAD (P) H dehydrogenases allow cytosolic NAD (P) H oxidation; under stress this may occur without high ROS production due to co-operation with AOX, which is activated by intermediates of the photorespiratory cycle.
Durum wheat mitochondria possess three energy-dissipating systems: the ATP-sensitive plant mitochondrial potassium channel (PmitoK (ATP)); the plant uncoupling protein (PUCP); and the alternative oxidase (AOX).

2791223 Haworth RA, Goknur AB, Berkoff HA: Inhibition of ATP-sensitive potassium channels of adult rat heart cells by antiarrhythmic drugs. Circ Res. 1989 Oct;65(4):1157-60.

Treatment of cells with rotenone plus p-trifluoromethoxyphenylhydrazone (FCCP) rapidly depleted ATP levels and strongly stimulated the rate of 86Rb uptake.
We conclude that 1) the stimulated 86Rb uptake is measuring ATP-sensitive potassium channel activity, 2) the ATP-sensitive potassium channel is strongly inhibited by quinidine, verapamil, and amiodarone, and 3) this inhibition may contribute to the antiarrhythmic action of these drugs.

We used next substrates of oxidation--0.35 mM succinate, 1 mM alpha-ketoglutarate, 3 mM glutamate, 3 mM pyruvate, 2.5 mM malate and inhibitor of the mitochondrial fermentative complex I (10 microM rotenone), succinate dehydrogenase inhibitor (2 mM malonate) and inhibitor of transamination (1 mM aminooxiacetate).

All of these stimuli act in a similar manner, i.e. by inhibiting a background TASK-like potassium channel (K (B)) they induce membrane depolarization and thus neurosecretion.
