Cardiovascular System Disease Models

Dexamethasone (Hexadecadrol) is a glucocorticoid receptor agonist, apoptosis inducer, and common disease inducer in experimental animals, constructing models of muscle atrophy, hypertension, and depression.

Dexamethasone also has potential for use in COVID-19 research.

Doxorubicin hydrochloride (Hydroxydaunorubicin hydrochloride; ADR), a cytotoxic anthracycline antibiotic, is an anti-cancer chemotherapy agent. Doxorubicin hydrochloride is a potent human DNA topoisomerase I and topoisomerase II inhibitor with IC₅₀s of 0.8 μM and 2.67 μM, respectively. Doxorubicin hydrochloride reduces basal phosphorylation of AMPK and its downstream target acetyl-CoA carboxylase. Doxorubicin hydrochloride induces apoptosis and autophagy.

Angiotensin II (Angiotensin II) is a vasoconstrictor and a major bioactive peptide of the renin/angiotensin system. Angiotensin II human plays a central role in regulating human blood pressure, which is mainly mediated by interactions between Angiotensin II and the G-protein-coupled receptors (GPCRs) Angiotensin II type 1 receptor (AT1R) and Angiotensin II type 2 receptor (AT2R). Angiotensin II human stimulates sympathetic nervous stimulation, increases aldosterone biosynthesis and renal actions. Angiotensin II human induces growth of vascular smooth muscle cells, increases collagen type I and III synthesis in fibroblasts, leading to thickening of the vascular wall and myocardium, and fibrosis. Angiotensin II human also induces apoptosis. Angiotensin II induces capillary formation from endothelial cells via the LOX-1 dependent redox-sensitive pathway.

Resiquimod is a Toll-like receptor 7 and 8 (TLR7/TLR8) agonist that induces the upregulation of cytokines such as TNF-α, IL-6 and IFN-α.

Isoprenaline (Isoproterenol) hydrochloride is a non-selective, orally active β-adrenergic receptor agonist. Isoprenaline has potent peripheral vasodilator, bronchodilator, and cardiac stimulating activities. Isoprenaline can be used for the research of bradycardia and bronchial asthma.

Semaxinib (SU5416) is a potent and selective inhibitor of VEGFR (Flk-1/KDR) with an IC₅₀ of 1.23 μM.

Uric acid is an orally active oxygen free radical scavenger that helps maintain stable blood pressure and combat oxidative stress. Uric acid can scavenge ROS, such as singlet oxygen and peroxynitrite, and inhibit lipid peroxidation. Uric acid can be used as a modeling agent in research on hyperuricemia-induced hypertension models.

Uric acid sodium is an orally active oxygen free radical scavenger that helps maintain stable blood pressure and combat oxidative stress. Uric acid sodium can scavenge ROS, such as singlet oxygen and peroxynitrite, and inhibit lipid peroxidation. Uric acid sodium can be used as a modeling agent in research on hyperuricemia-induced hypertension models.

Norepinephrine (Levarterenol; L-Noradrenaline) is a potent adrenergic receptor (AR) agonist. Norepinephrine activates α₁, α₂, β₁ receptors.

L-NAME hydrochloride inhibits NOS with an IC₅₀ of 70 μM. L-NAME is a precursor to NOS inhibitor L-NOARG which has an IC₅₀ value of 1.4 μM. L-NAME hydrochloride requires hydrolysis of the methyl ester by cellular esterases to become a fully functional inhibitor. L-NAME hydrochloride can be used to induce hypertension and preeclampsia models.

Carfilzomib (PR-171) is an irreversible proteasome inhibitor with an IC₅₀ of 5 nM in ANBL-6 and RPMI 8226 cells.

Monocrotaline is an 11-membered macrocyclic pyrrolizidine alkaloid. Monocrotaline inhibits OCT-1 and OCT-2 with IC₅₀s of 36.8 µM and 1.8 mM, respectively. Monocrotaline has antitumor activity and is cytotoxic to hepatocellular carcinoma cells. Monocrotaline is used to induce a model of pulmonary hypertension in rodents. ^[2][6][8].

Busulfan is a potent alkylating antineoplastic agent. Busulfan causes DNA damage by cross-linking DNAs and DNA and proteins. Busulfan inhibits thioredoxin reductase. Busulfan induces apoptosis. Busulfan is an immunosuppressive and myeloablative chemotherapeutic agent.

Norepinephrine (Levarterenol; L-Noradrenaline) hydrochloride is a potent adrenergic receptor (AR) agonist. Norepinephrine activates α₁, α₂, β₁ receptors.

Calcium chloride anhydrous, for cell culture is an inorganic salt for the preparation of various buffers. Calcium chloride anhydrous, for cell culture can be used for animal modeling, to construct abdominal aortic aneurysm models.

Angiotensin II human (Angiotensin II) acetate is a vasoconstrictor and a major bioactive peptide of the renin/angiotensin system. Angiotensin II human acetate plays a central role in regulating human blood pressure, which is mainly mediated by interactions between Angiotensin II and the G-protein-coupled receptors (GPCRs) Angiotensin II type 1 receptor (AT1R) and Angiotensin II type 2 receptor (AT2R). Angiotensin II human acetate stimulates sympathetic nervous stimulation, increases aldosterone biosynthesis and renal actions. Angiotensin II human acetate induces growth of vascular smooth muscle cells, increases collagen type I and III synthesis in fibroblasts, leading to thickening of the vascular wall and myocardium, and fibrosis. Angiotensin II human acetate also induces apoptosis. Angiotensin II human acetate induces capillary formation from endothelial cells via the LOX-1 dependent redox-sensitive pathway.

L-Homocysteine, an amino acid, is a homocysteine that has L configuration. Homocysteine is an essential intermediate in normal mammalian metabolism of methionine. L-Homocysteine induces upregulation of Cathepsin V that mediates vascular endothelial inflammation in hyperhomocysteinaemia.

Tyloxapol is a nonionic liquid polymer of the alkyl aryl polyether alcohol type, used as a surface active stabilizer. Tyloxapol is used to induce hyperlipidemia in animals.

Trimethylamine N-oxide is a gut microbe-dependent metabolite of dietary choline and other trimethylamine-containing nutrients. Trimethylamine N-oxide induces inflammation by activating the ROS/NLRP3 inflammasome. Trimethylamine N-oxide also accelerates fibroblast-myofibroblast differentiation and induces cardiac fibrosis by activating the TGF-β/smad2 signaling pathway.

Yohimbine hydrochloride is an alpha-2 renal adenomatase receptor inhibitor, blocking pre- and post-contact alpha-2 renal adenomatase receptors, causing the release of renal adenoma and multiple sclerosis.
