Is there a therapeutic future for "potassium channel openers'?
1. Potassium channels, which control cell electrical activity, are among the most regulated of all ion channels in biology. Promotion of activity in K+ channels by a wide range of physiological factors tends to stabilize cell function. 2. The discovery of synthetic molecules (e.g. cromakalim) that 'directly' open ATP-sensitive K+ channels has led to a new direction in pharmacology. ATP-sensitiv...
متن کاملSynthesis and Vasorelaxant Effect of 9-aryl-1,8-acridinediones as Potassium Channel Openers in Isolated Rat Aorta
ATP-sensitive potassium (KATP) channel openers have a relaxation effect due to the lower cellular membrane potential and inhibit calcium influx. There has been considerable interest in exploring KATP channel openers in the treatment of various diseases such as cardiovascular, cerebrovascular, and urinary system disease and premature labor. The purpose of this study was to synthesize 3,3,6,6-tet...

متن کاملActions of potassium channel openers in rat detrusor urinae.
This study was performed to investigate the action of potassium channel openers on the mechanical activity of detrusor muscle isolated from rats. Detrusor muscle strips, 15 mm in length, were myographied isometrically in an isolated organ bath. P 1060, RP 49356 and BRL 38277, potassium channel activators, reduced the basal tone and diminished the phasic activity of detrusor concentration-depend...
متن کاملPharmacodynamics of potassium channel openers in cultured neuronal networks.
A novel class of drugs - potassium (K(+)) channel openers or activators - has recently been shown to cause anticonvulsive and neuroprotective effects by activating hyperpolarizing K(+) currents, and therefore, may show efficacy for treating tinnitus. This study presents measurements of the modulatory effects of four K(+) channel openers on the spontaneous activity and action potential waveforms...
