angiotensin ii , human

Angiotensin II (5-8) is an endogenous C-terminal fragment of the peptide vasoconstrictor angiotensin II

Angiotensin II is a potent direct vasoconstrictor, causing arteries and veins to constrict, so leading to an increase in blood pressure. Angiotensin also potentiates the release of norepinephrine by a direct action on postganglionic sympathetic fibers.

Angiotensin II human TFA 是肾素-血管紧张素系统中的强效血管收缩剂，通过与 AT1R 和 AT2R 受体作用调节血压，可激活交感神经、促进醛固酮合成和肾功能，诱导血管平滑肌细胞增殖及成纤维细胞中 I 型和 III 型胶原合成，导致血管和心肌增厚、纤维化，并诱导凋亡及促进毛细血管生成，可用于构建心脏肥大、高血压和腹主动脉瘤模型。

Angiotensin II (3-8), human (TFA) is an angiotensin AT1 receptor agonist with less activity.

Angiotensin II is a potent direct vasoconstrictor, causing arteries and veins to constrict, so leading to an increase in blood pressure.

Angiotensin II 是一种主要的生物活性血管收缩肽，通过与AT1R和AT2R受体结合，调节血压，刺激交感神经，促进醛固酮合成和肾脏功能。它还能诱导血管平滑肌细胞增生、胶原合成增加，导致血管和心肌增厚及纤维化，同时促进细胞凋亡和内皮细胞毛细血管形成。Angiotensin II常用于诱导高血压和心脏肥大动物模型。

Angiotensin II human acetate 是肾素-血管紧张素系统中的主要血管收缩肽，通过与AT1R和AT2R受体结合调节血压，刺激交感神经，促进醛固酮合成和肾脏功能，诱导血管平滑肌细胞增生和胶原合成，导致血管及心肌增厚和纤维化，同时促进细胞凋亡和内皮毛细血管形成。常用于诱导高血压和心脏肥大模型。

CAY10434是一种有作用的 CYP4A 羟化酶 (CYP4A hydroxylase) 抑制剂，在人肾微粒体测试中的 IC50值为8.8 nM。CAY 10434 在改善血管紧张素 II 的收缩过程中 Emax 为 6764 mg。

Angiotensin I-13C6,15N (human, mouse, rat) TFA 是经过13C 和15N 标记的蛋白质,具体为Angiotensin I (human, mouse, rat) TFA 的同位素标记形式。此化合物作为angiotensin II的前体，在血管紧张素转化酶 (ACE) 的作用下被裂解, 产生angiotensin II。

Eprosartan (SKF-108566J free base) 是一种具有选择性和竞争性的非肽类血管紧张素II受体拮抗剂，对AT1受体亚型具有高亲和力，可用作降压剂。Eprosartan 对血管紧张素 II 受体有抑制作用，在大鼠和人类肾上腺皮质膜中的 IC50 值分别为 9.2 nM 和 3.9 nM。

Losartan Carboxylic Acid (E-3174) 是 Losartan 的活性羧酸代谢产物，是血管紧张素Ⅱ受体 1 型(AT1)拮抗剂。它能够阻断血管紧张素 II 诱导的血管平滑肌细胞反应，可以提高血浆肾素活性，降低平均动脉压。

4-hydroxy Valsartan is a major metabolite of the angiotensin II type 1 (AT1) receptor antagonist valsartan . It reduces platelet aggregation induced by epinephrine and collagen but not ADP in human whole blood.

Telmisartan acyl-β-D-glucuronide is a major metabolite of the angiotensin II receptor antagonist telmisartan . It does not bind human serum albumin and is cleared from rat plasma with a clearance rate of 180 ml/min/kg following intravenous administration.

Prostaglandin A1 (PGA1) was first isolated as a dehydration product of the PGE1 compounds found in human semen. 15-keto PGA1 is a metabolite of PGA1, produced by 15-hydroxy PG dehydrogenase. It can be produced from PGA1 in pig lung, trachea, aorta, and pulmonary artery tissue preparations. 15-keto PGA1, given at a concentration of 6 μM, causes vasoconstriction of rabbit lung that is comparable to that induced by angiotensin II.

AT2R antagonist 1 是一种高度选择性的、有效的 AT2R (血管紧张素 II AT2 受体)配体。AT2R antagonist 1 能够高度亲和 AT2R 亲和力 (Ki: 29 nM)。AT2R antagonist 1 能够抑制常见的药物代谢CYP 酶，在人、大鼠和小鼠肝微粒体中具有较高的稳定性。

Angiotensin III, human, mouse (Angiotensin III, human, mouse(3TFA)) 是一种七肽，是血管紧张素 2 型受体 (AT2R) 激动剂，能够作用于 AT2R (IC50:0.648 nM)及 AT1R (IC50:21.1nM)。

Safflor yellow B 通过抑制血管紧张素 II 介导的人脐静脉细胞损伤，调节 Bcl-2/p22 (phox) 表达，展现出神经保护作用。

18-Hydroxy-11-deoxy Corticosterone (18-OH-DOC) is a mineralocorticoid produced by the zona fasciculata of the adrenal gland, with its biosynthesis regulated by adrenocorticotropic hormone (ACTH) and angiotensin II. This regulation heightens 18-OH-DOC production in isolated human adrenal glomerulosa cells and allows for its formation from 11-deoxy corticosterone (DOC) in human SK-MEL188 melanoma cells. As an intermediate in progesterone metabolism, 18-OH-DOC can be converted to aldosterone in rat adrenal glands' capsular portion. Its continuous infusion (200 μg/rat per day) has been shown to raise systolic blood pressure in uninephrectomized saline-drinking rats, and elevated plasma levels of 18-OH-DOC have been observed in the adb/db mouse model of type 2 diabetes.

Angiotensin I (human, mouse, rat) 是血管紧张素Ⅱ的前体物质，在血管紧张素转化酶 (ACE) 的参与下裂解成血管紧张素Ⅱ。
