Biochem/physiol Actions
Alinidine is an HCN Channel blocker of neuronal Ih, related cardiac If channels and ATP-sensitive Kir channels. It is an analog of clonidine; bradycardic and antiarrhythmic agent (sinus tachyarrhythmias). Alinidine affects physiological markers in conscious dogs. Alinidine in four intravenous (i.v.) injections of 0.5, 0.5, 1, and 2 mg/kg, decreased sinus rate (< or = 43%) and ventricular rate (< or = 44%), but increased atrial rate (< or = 31%). It lengthened CSRT (< or = 71%) at the two highest doses and increased AERP (< or = 33%) and decreased WP (< or = 33%) at all doses. Alinidine did not modify mean blood pressure at any dose in either group. These results indicate that alinidine exhibits electrophysiologic effects in conscious dogs that reflect the marked antiarrhythmic potential of this agent, apart from its assumed antiischemic properties.

The goal of the present study was to further characterize the effects of the novel cardioprotective agent BMS-180448 on potassium fluxes in cardiac and vascular smooth muscle. Exposure of voltage-clamped guinea pig ventricular myocytes to BMS-180448 (300 microM) produced an

1. ZENECA ZD7288 (4-(N-ethyl-N-phenylamino)-1,2-dimethyl-6-(methylamino) pyridinium chloride) is a sinoatrial node (SAN) modulating agent which produces a selective slowing of the heart rate. Its effects have been studied in single, freshly dissociated guinea-pig SAN cells, by standard patch clamp procedures. 2.

1. Intracellular recordings were made from pyramidal neurons in layers II/III and V of rat visual cortical slices. Distal and proximal excitatory postsynaptic potentials (EPSPs) were evoked using extracellular bipolar electrodes placed on the slice horizontal to each cell, near

The antiischemic and antiarrhythmic effects of alinidine and a number of novel alinidine analogs were examined by using perfused rat-heart models. In the isolated working rat heart, the alinidine analog TH91:21 (10 microM; a butyl derivative) significantly increased the postischemic

1. Ring segments of rat thoracic aorta were suspended in organ baths to record isometric tension. Tissues were precontracted with K+ (20 mmol/L), and full concentration-relaxation curves constructed to cromakalim (0.01-30 mumol/L) in the absence and presence of increasing concentrations
