| In vitro study | Amlodipine benzenesulfonic acid reduces the decrease of p85aPI3K, phosphorylated Akt, phosphorylated GSK-3β, heat-shock transcription factor 1 and Bcl-2-induced H2O2, and cyclooxygenase-2, cytoplasmic cytochrome c, lysis of caspase9, and an increase in neuronal cell lysis of caspase3. In angiotensin Ⅱ-infused mice, Amlodipine significantly reduced systolic blood pressure (SBP), aortic hypertrophy, endothelial dysfunction, expression of LOX-1, aortic O2(-) and ONOO(-) production and plasma free 8-F(2) α-isoprostane levels. In isolated, precontracted, endothelium intact porcine coronary arteries, Amlodipine elicited NO-mediated relaxation and left-shift of concentration-relaxation curves of bradykinin. In native endothelial cells, Amlodipin increased NO production, detected by electron spin resonance spectroscopy, and stimulated cyclic GMP levels up to 8-fold in cultured endothelial cells. Amlodipine induces NO-mediated relaxation of rat aortic rings and does not express B2 receptors. In endothelial cells, Amlodipine time-dependently attenuates phosphorylation of protein kinase C(PKC), similar to the time course of phosphorylation of eNOS, and prevent the activation of PKC induced by phorbol -12-myristate -13-acetate. |
| In vivo study | In cats, in porcine coronary arteries with intact endothelium, Amlodipine significantly reduced mean indirect systolic blood pressure from 198mm Hg to 155mm Hg. Amlodipine benzenesulfonic acid appears to be a safe and effective oral drug for the treatment of systemic hypertension in cats. |
