Synthesis and Effects of Novel Dihydropyridines as Dual Calcium Channel Blocker and Angiotensin Antagonist on Isolated Rat Aorta
Objective(s) Four novel losartan analogues 5a-d were synthesized by connecting a dihydropyridine nucleus to imidazole ring. The effects of 5a and 5b on angiotensin receptors (AT') and L-type calcium channels were investigated on isolated rat aorta. Materials and Methods Aortic rings were pre-contracted with 1 pM Angiotensin II or 80 mM KCl and relaxant effects of losartan, nifedipine, 5a and...
متن کاملPharmacological Profile of Flunarizine: a Calcium Channel Blocker
Flunarizine is a non selective calcium channel antagonist. It is highly lipophilic compound which distributes preferentially in adipose tissue and passes the blood brain barrier readily. Numerous preclinical and controlled clinical studies, including double blind clinical studies in which the drug was compared with placebo or standard drugs in particular disease showing efficacy in migraine, ve...
متن کاملPrevention of transcoronary macromolecular leakage after ischemia-reperfusion by the calcium entry blocker nisoldipine. Direct observations in isolated rat hearts.
Coronary microvascular damage appears to play a role in reperfusion injury after myocardial ischemia. This study was designed to afford direct viewing of the effects of myocardial ischemia-reperfusion on the coronary microcirculation and to determine whether pretreatment with the calcium blocker nisoldipine would attenuate any microvascular damage during reperfusion. Four groups of isolated rat...
متن کاملInvolvement of voltage-dependent calcium channels in synaptic plasticity of the rat visual cortex
In this study, involvement ofvoltage-dependent calcium channels in LTP of responses of rat visual cortex slices was analyzed. Field potentials including EPSP1 and EPSP2 from layers II/III were recorded through stimulation of layer IV. Whereas nifedipine, a L-type calcium channel blocker (L-VDCC), did not considerably affect the LTP of responses, but Ni2+, a relatively selective blocker of T-typ...
