Mitochondrial permeability transition occurs through a Ca2+-dependent opening of a transmembrane pore, whose identity has been attributed to that of the adenine nucleotide translocase (ANT). In this work, we induced permeability transition by adding 0.5 micro...

Environment-selective synergistic toxicity using combinations of aldehydes and hydrazine derivatives was demonstrated in two different model systems in vitro. Combinations of 5-nitro-2-furaldehyde with semi-carbazide and of 2-hydrazinopyridine with pyridine-2...

This study shows that the hydrophobic cation octylguanidine protects against myocardial damage induced by ischemia-reperfusion. The protective effect of the amine was analyzed after 5 min of coronary occlusion followed by 5 min reperfusion in rat hearts. ECG ...

The effects of octylguanidine on the mechanical activity of Guinea-pig heart were investigated. The negative inotropic effect took place in a biphasic manner with a first fast contraction decline process followed, after a temporaneous steady state, by a secon...

The effects of octylguanidine on electrical activity of Guinea-pig heart were investigated. The substance (2.7 x 10(-4)M) initially reduced the rate of rise of the action potential without a concomitant modification of the other action potential without a con...

Kinetics of pyrethroid-modified sodium channels and the interaction of N-octylguanidine with the modified channels have been studied with internally perfused and voltage-clamped squid giant axons. The pyrethroids used were 1R-cis-phenothrin; 1R-cis-permethrin...

In yeast, Ca(2+) and long chain alkylguanidines interact with mitochondria modulating the opening of the yeast mitochondrial unspecific channel. Mammalians possess a similar structure, the mitochondrial permeability transition pore. The composition of these p...

The effects of intracellular application of three compounds - QX314, N-ethylguanidine and N-octylguanidine - on the acetylcholine-activated ionic channels in chick myoballs were examined. Voltage-clamped myoballs were internally perfused using the suction-pip...

J. Gen. Physiol. 85 , 603-620, (1985)

The time-, frequency-, and voltage-dependent blocking actions of several cationic drug molecules on open Na channels were investigated in voltage-clamped, internally perfused squid giant axons. The relative potencies and time courses of block by the agents (p...

We have studied the inhibitory effects of several cations (OG+, Mg2+, Ca2+, Sr2+, Ba2+, Mn2+, La3+) on the uniport and exchange pathways for Na+ and K+ of rat liver mitochondria. Swelling of mitochondria suspended in sodium or potassium acetates indicates tha...
