Azilsartan (TAK-536) 是一种口服有效的、选择性和特异性的血管紧张素 Ⅱ 1 型受体 (AT1) 拮抗剂。Azilsartan 诱导 HepG2 细胞ROS形成和细胞凋亡 (apoptosis)。Azilsartan 具有神经保护和抗癌活性。Azilsartan 可以用于高血压和中风研究。
生物活性 | Azilsartan (TAK-536) is an orally active, potent, selective and specificangiotensin II type 1 receptor (AT1)antagonist. Azilsartan inducesROSformation andapoptosisin HepG2 cells. Azilsartan shows neuroprotective and anticancer activity. Azilsartan can be used for hypertension and stroke research[1][2][3][4][5]. |
体外研究 (In Vitro) | Azilsartan (0-200 μM, 0-72 h) decreases the viability of HepG2 cells[5]. Azilsartan (100 μM, 24 h) induces apoptosis in HepG2 cells[5]. Azilsartan inhibits the specific binding of125I-Sar1-Ile8-AII to human angiotensin type 1 receptors with an IC50of 2.6 nM[3]. Azilsartan potently inhibits aortic endothelial and vascular cell proliferation in the absence of exogenous Ang II supplementation[5]. Azilsartan enhances adipogenesis and exerted greater effects thanValsartan(HY-18204) on expression of genes encoding peroxisome proliferator-activated receptor-α (PPARα), PPARδ, leptin, adipsin, and adiponectin[1].
Cell Proliferation Assay[5] Cell Line: | HepG2 and KDR cells | Concentration: | 5, 25, 50, 100 and 200 μM | Incubation Time: | 24, 48, and 72 h | Result: | Gradually decreased the viability of HepG2 cells by increasing the incubation time and dose, the inhibitory concentration of Azilsartan (IC 50%) against HepG2 cells was 100 μM for 24 h treatment time point while in KDR epithelial normal cells no significant cytotoxic effect was observed during the similar treatment conditions. |
Apoptosis Analysis[5] Cell Line: | HepG2 cells | Concentration: | 100 μM | Incubation Time: | 24 h | Result: | Induced 57.2% early and 0.52% late apoptosis respectively after 24 h. |

体内研究 (In Vivo) | Azilsartan (0-3 mg/kg, Oral gavage, once daily for 5 days) decreases SBP (systolic blood pressure) in obese Koletsky rats at 2 mg/kg[2]. Azilsartan (0-2 mg/kg, Oral gavage, once daily for 21 days) lowers blood pressure and basal plasma insulin concentration[2]. Azilsartan (2 and 4 mg/kg; PO, daily for 9 days) offers protection against ischemia induced secondary brain injury[4].
Animal Model: | Male Wistar-Kyoto (WKY) rats, obese Koletsky rats (n=6 per group)[2] | Dosage: | 0, 1, 2 and 3 mg/kg | Administration: | Oral gavage, once daily (9:00-10:00 hours) for 5 days | Result: | Decreased SBP (systolic blood pressure) in obese Koletsky rats to that of normal rats at 2 mg/kg, whereas the 3 mg/kg dose elicited hypotension. |
Animal Model: | Obese Koletsky rats (16, n = 8 per group)[2] | Dosage: | 0 and 2 mg/kg | Administration: | Oral gavage, once daily (9:00-10:00 hours) for 21 days | Result: | Lowered blood pressure, basal plasma insulin concentration and the homeostasis model assessment of insulin resistance index, and inhibited over-increase of plasma glucose and insulin concentrations during oral glucose tolerance test. |
Animal Model: | Male Wistar Rats (240–280 g)[4] | Dosage: | 0, 2, and 4 mg/kg | Administration: | Orally, daily for 9 days, starting 7 days before the day of surgery | Result: | Individual treatments with Azilsartan (2 & 4 mg/kg) andCoenzyme Q10(HY-N0111) (20 & 40 mg/kg) significantly attenuated the reduction in locomotor activity. Further, combination treatment with azilsartan (2 mg/kg) and Coenzyme Q10 (20 mg/kg) significantly improved the locomotor activity of animals as compared to their effects per se in BCCAO treated animals. |
