Lacidipine 是一种口服有效的和具有高度选择性的 L 型钙离子通道阻滞剂,作用于平滑肌的钙通道,主要扩张周围动脉,减少外周阻力,具有长效抗高血压活性。Lacidipine 通过调节caspase-3途径来保护 HKCs 免受 ATP 耗尽和恢复所诱发的凋亡。Lacidipine 可用于高血压,动脉粥样硬化和急性肾脏损伤的研究。
生物活性 | Lacidipine is an orally active and highly selectiveL-type calcium channelblocker that acts on smooth muscle calcium channels, primarily dilates peripheral arteries, reduces peripheral resistance, and has long-lasting anti-hypertensive activity. Lacidipine protects HKCs fromapoptosisinduced by ATP depletion and recovery by modulating thecaspase-3pathway. Lacidipine can be used in studies of hypertension, atherosclerosis and acute kidney injury (AKI)[1][2]. |
体外研究 (In Vitro) | Lacidipine (0.01-100 μM; 24 h) inhibits HKCs proliferation in vitro in a concentration-dependent manner[1]. Lacidipine (0.01-100 μM; 24 h) protects HKCs against apoptosis induced by ATP depletion and recovery by regulating the caspase-3 pathway[1].
Cell Proliferation Assay[1] Cell Line: | HKC cells | Concentration: | 0.01-100 μM | Incubation Time: | 24 h | Result: | Exhibited anti-proliferative activity in a concentration-dependent manner. |
Apoptosis Analysis[1] Cell Line: | HKC cells (renal ischemia reperfusion (I/R) model) | Concentration: | 1, 10 μM | Incubation Time: | 24 h | Result: | AA-induced HKC cells apoptosis, with proportion of early apoptotic cells of 1.47% and 0.30% for 1 and 10 μM dosage, respectively. |
Western Blot Analysis[1] Cell Line: | HKC cells (renal ischemia reperfusion (I/R) model) | Concentration: | 1, 10 μM | Incubation Time: | 24 h (pretreat) | Result: | Decreased the expression of cyt c of injured cells following ATP depletion and recovery. Significantly increased the expression of the Bcl-2 protein, but decreased the Bax protein. |

体内研究 (In Vivo) | Lacidipine (0.3, 1.0, 3.0 mg/kg; p.o.; single daily for 10 weeks) shows anti-atherogenic effects in the apoE-deficient mouse, and reduces plasma endothelin concentrations[2].
Animal Model: | Female C57BL/6 mice (Homozygous; apoE-deficient; atherosclerosis model)[2]. | Dosage: | 0.3, 1.0, 3.0 mg/kg | Administration: | Oral gavage; single daily for 10 weeks. | Result: | Induced a significant dose-dependent decrease in plasma endothelin levels. Significantly reduced the mean lesion area in a dose-related manner by 10, 17 and 53% for 0.3, 1.0, 3.0 mg/kg, respectively. |
