Angiotensin (1-7) (Synonyms:Ang-(1-7))
目录号 : KM2972 CAS No. : 51833-78-4

Angiotensin 1-7 (Ang-(1-7)) 是肾素-血管紧张素系统 (RAS) 中的一种内源性七肽,由于其在心肌细胞中的抗炎和抗纤维化活性而具有心脏保护作用。Angiotensin 1-7 抑制纯化的犬血管紧张素转换酶 (ACE) 活性,IC50 值为 0.65 μM。Angiotensin 1-7 通过抑制血管紧张素转换酶和释放一氧化氮,可作为激肽诱导的血管舒张的局部协同调节剂。Angiotensin 1-7 阻断 Ang II 诱导的平滑肌细胞增殖和肥大,并显示对内皮的抗血管生成和生长抑制作用。Angiotensin 1-7 显示出抗炎活性。

生物活性

Angiotensin 1-7 (Ang-(1-7)) is an endogenous heptapeptide from the renin-angiotensin system (RAS) with a cardioprotective role due to its anti-inflammatory and anti-fibrotic activities in cardiac cells. Angiotensin 1-7 inhibits purified canine ACE activity (IC50=0.65 μM). Angiotensin 1-7 acts as a local synergistic modulator of kinin-induced vasodilation by inhibiting ACE and releasing nitric oxide. Angiotensin 1-7 blocks Ang II-induced smooth muscle cell proliferation and hypertrophy and shows antiangiogenic and growth-inhibitory effects on the endothelium. Angiotensin 1-7 shows anti-inflammatory activity .

体外研究

Angiotensin 1-7 (Ang-(1-7)) inhibits cultured vascular smooth muscle cell growth, whereas equal molar concentration of Ang II stimulates cell growth.
Angiotensin 1-7 (Ang 1-7) abrogates the methylglyoxal-modified albumin (MGA)-stimulated myofibroblast phenotype by inhibiting the chronic stimulation of the TGF-β-ERK pathway in NRK-52E cells.
Angiotensin 1-7 signals through the Mas receptor ( MasR) in opposition to Ang II/angiotensin II type 1 receptor (AT1R), promoting anti-inflammatory,vasodilatory, and neuroprotective effects.

体内研究

Daily Angiotensin 1-7 (Ang-(1-7)) treatment (0.01-0.06 mg/kg) results in significant amelioration of DSS-induced colitis. Colitis-associated phosphorylation of p38, ERK1/2 and Akt is reduced by Ang 1-7 treatment.

The molarity calculator equation
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
The dilution calculator equation
Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2
