描述 | Nicardipine is a calcium channel blocker with an IC50 of 1 μM for blocking cardiac calcium channels. Nicardipine acts as an agent for chronic stable angina and for controlling blood pressure. Nicardipine is a less potent Ca++ antagonist than nifedipine in atrial fibers and that the reduction of delayed potassium current, which occurs in a similar range of concentrations to the blockade of Isi, could also be involved in its therapeutic effects[3]. Nicardipine is more specific for vascular smooth muscle than for cardiac smooth muscle and for coronary than peripheral vasculature[4]. Nicardipine (10-12 to 10-8 M) decreased active tension and frequency of contraction in a concentration-dependent manner. The EC50 and EC95 of nicardipine in the inhibition of active tension of the uterine smooth muscle were 2.41 × 10-10 M and 3.06 × 10-7 M, respectively. The EC50 and EC95 of nicardipine in the inhibition of frequency of contraction of the uterine smooth muscle were 9.04 × 10-11 and 4.18 × 10-7 M, respectively[5]. CaMKII down-regulation/proteasome inhibition/cytosolic calcium up-regulation/cathepsin B activation/trypsinogen activation axis was present in pancreatic acinar cells injury under nicardipine treatment[6]. |
