Research Area

• Description: Cardiovascular Disease

Biological Activity

• Description: Perindopril Erbumine (Aceon) is a potent ACE) inhibitor with IC50 of 1.05 nM.
• Targets: ACE
• IC50: 1.05 nM ^[1]
• In Vitro: Perindopril Erbumine displays a higher binding affinity for the bradykinin binding sites than the angiotensin I binding sites of the angiotensin-converting enzyme (ACE) with bradykinin/angiotensin I selectivity ratio of 1.44. ^[1] Perindopril Erbumine inhibits the angiotensin- and Aβ42-to-Aβ40-converting activity of mutated ACE containing two active domains (F-ACE) with IC50 of 0.03-0.1 μM, and 0.01-0.03 μM, respectively. ^[2] Perindopril Erbumine (~2 μM) displays no significant cytotoxicity towards SCC-VII and KB cells, but can significantly reduce the production of angiotensin II and the transcription of VEGF in KB cells in a concentration-dependent manner. ^[3]
• In Vivo: Oral administration of Perindopril Erbumine at 2 mg/kg/day has a significant inhibitory effect on SCC-VII tumor growth, and reduces blood vessel formation surrounding the tumors in vivo due to the suppression of VEGF-induced angiogenesis. ^[3] Administration of Perindopril Erbumine at 2 mg/kg/day displays a strong inhibitory effect of the BNL-HCC tumor growth in rats similar to that of 20 mg/kg/day and in contrast to the AT1-R antagonist candesartan or losartan which at the dose of 20 mg/kg/day has no inhibitory effect. ^[4] Administration of Perindopril Erbumine at 3 mg/kg/day significantly inhibits LPS-induced apoptosis by 6.4% in RAECs in vivo than that of ramipril by 3.2%. ^[5] Administration of Perindopril Erbumine (1 mg/kg/day) significantly suppresses the hippocampal ACE activity, and prevents cognitive impairment and brain injury in rats with Alzheimer’s disease (AD). ^[6]
• Clinical Trials: A Phase III study to evaluate the efficacy and safety of a fixed-dose combination of Perindopril Arginine plus Amlodipine Besylate versus Perindopril Erbumine and Amlodipine Besylate in subjects with essential hypertension is currently recruiting participants.

Protocol

• Protocol: Kinase Assay ^[1]
• ACE inhibitor binding assay: The binding assay is based on the competitive displacement of [^125I]351A by Perindopril Erbumine and performed on whole endothelial cells. Subconfluent HUVECs in 6-well plates are rinsed with 2 mL binding buffer (140 mM NaCl, 2.7 mM KCl, 1.8 mM CaCl₂, 1.03 mM MgCl₂, 0.42 mM NaH₂PO₄, 10 mM HEPES, 2 mM sodium pyruvate, 5 mM glucose, pH 7.4), and the culture medium is replaced with 2.5 mL fresh binding buffer containing 5% fetal bovine serum (FBS). A set concentration of Perindopril Erbumine (2.5–12.5 μL, 0.1–50 nM) is added to the binding buffer. A saturating amount of [^125I]351A (10 μL, typically 10^6 cpm) is then added to each sample and the plates are incubated at 37 °C for 2 hours in a thermostatic bath. The cells are then rinsed twice with 1.5 mL binding buffer. Finally, the cells are extracted with 0.5 mL NaOH 1 N, incubated for 5 minutes, and the radioactivity is counted with a gamma counter. The radioactivity, which is due to [^125I]351A binding, is inversely related to Perindopril Erbumine's affinity for endothelial ACE. The concentration of Perindopril Erbumine that displaces 50% of the bound radioligand is calculated from the competition curve.
