angiotensin ii human

Angiotensin II human (Ang II) 是一种生物活性肽，一种血管收缩剂。Angiotensin II 可以与 AT1R 和 AT2R 相互作用，调节人类血压，刺激交感神经，增加醛固酮生物合成和肾脏活动。

Angiotensin II human acetate (DRVYIHPF acetate) 是血管收缩剂，是肾素 血管紧张素系统的主要生物活性肽，在调节人类血压中起着核心作用。它刺激交感神经刺激，增加醛固酮生物合成和肾脏活动。它诱导血管平滑肌细胞生长，也诱导细胞凋亡。它通过 LOX-1 依赖的氧化还原敏感途径诱导内皮细胞毛细血管形成。

Angiotensin II human (Angiotensin II) TFA 作为肾素 血管紧张素系统中关键的生物活性肽，扮演着血管收缩剂的角色并在调节人体血压中发挥中心作用。其主要通过与 G 蛋白偶联受体 (GPCRs)、血管紧张素 II 1型受体 (AT1R) 和血管紧张素 II 2型受体 (AT2R) 的相互作用来介导效应，包括刺激交感神经系统、增加醛固酮的生物合成和肾脏功能。此外，Angiotensin II human TFA 促进血管平滑肌细胞的生长和 I 型及 III 型胶原在成纤维细胞中的合成，导致血管壁与心肌增厚及纤维化，并诱导细胞凋亡。还通过LOX-1依赖的氧化还原敏感路径诱导内皮细胞中的毛细血管形成。

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

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.

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.

Angiotensin II (3-8), human 是活性稍弱的血管紧张素AT1受体激动剂。

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。
