Cholesterol (Standard) is the analytical standard of Cholesterol. This product is intended for research and analytical applications. Cholesterol is the major sterol in mammals. It is making up 20-25% of structural component of the plasma membrane. Plasma membranes are highly permeable to water but relatively impermeable to ions and protons. Cholesterol plays an important role in determining the fluidity and permeability characteristics of the membrane as well as the function of both the transporters and signaling proteins. Cholesterol is also an endogenous estrogen-related receptor α (ERRα) agonist.

Progesterone (Standard) is the analytical standard of Progesterone. This product is intended for research and analytical applications. Progesterone is a steroid hormone that regulates the menstrual cycle and is crucial for pregnancy.

Dexamethasone (Standard) is the analytical standard of Dexamethasone. This product is intended for research and analytical applications. Dexamethasone (Hexadecadrol) is a glucocorticoid receptor agonist. Dexamethasone also significantly decreases CD11b, CD18, and CD62L expression on neutrophils, and CD11b and CD18 expression on monocytes. Dexamethasone is highly effective in the control of COVID-19 infection. Dexamethasone inhibits production of exosomes containing inflammatory microRNA-155 in lipopolysaccharide-induced macrophage inflammatory responses.

Beta-Sitosterol (Standard) is the analytical standard of Beta-Sitosterol. This product is intended for research and analytical applications. Beta-Sitosterol (purity≥80%) is orally active. Beta-Sitosterol exhibits multiple activities, including anti-inflammatory, anticancer, antioxidant, antimicrobial, antidiabetic, antioxidant enzyme, and analgesic. Beta-Sitosterol inhibits inflammation and impaired adipogenesis in bovine mammary epithelial cells by reducing levels of ROS, TNF-α, IL-1β, and NF-κB p65 and restoring the activity of the HIF-1α/mTOR signaling pathway. Beta-Sitosterol induces apoptosis in cancer cells through ROS-mediated mitochondrial dysregulation and p53 activation. Beta-Sitosterol exerts its anticancer effects in cancer cells by activating caspase-3, caspase-8, and caspase-9, mediating PARP inactivation, MMP loss, altered Bcl-2-Bax ratio, and cytochrome c release. Beta-Sitosterol modulates macrophage polarization and reduces rheumatoid inflammation in mice. Beta-Sitosterol inhibits tumor growth in multiple mouse cancer models. Beta-Sitosterol can be used in the research of arthritis, lung cancer, breast cancer and other cancers, diabetes, etc.

Estrone (Standard) is the analytical standard of Estrone. This product is intended for research and analytical applications. Estrone (E1) is a natural estrogenic hormone. Estrone is the main representative of the endogenous estrogens and is produced by several tissues, especially adipose tissue. Estrone is the result of the process of aromatization of androstenedione that occurs in fat cells.

Corticosterone (Standard) is the analytical standard of Corticosterone. This product is intended for research and analytical applications. Corticosterone (17-Deoxycortisol) is an orally active and adrenal cortex-produced glucocorticoid, which plays an important role in regulating neuronal functions of the limbic system (including hippocampus, prefrontal cortex, and amygdala). Corticosterone increases the Rab-mediated AMPAR membrane traffic via SGK-induced phosphorylation of GDI. Corticosterone also interferes with the maturation of dendritic cells and shows a good immunosuppressive effect.

Ergosterol (Standard) is the analytical standard of Ergosterol. This product is intended for research and analytical applications. Ergosterol is the primary sterol found in fungi, with antioxidative, anti-proliferative, and anti-inflammatory effects.

Prednisolone (Standard) is the analytical standard of Prednisolone. This product is intended for research and analytical applications. Prednisolone is a potent, orally active corticosteroid and a glucocorticoid. Prednisolone possesses about four times the anti-inflammatory activity of hydrocortisone while causing less salt and water retention. Prednisolone can be used for ocular, anti-inflammatory research.

Methylprednisolone (Standard) is the analytical standard of Methylprednisolone. This product is intended for research and analytical applications. Methylprednisolone is a synthetic corticosteroid with anti-inflammatory and immunomodulating properties. Methylprednisolone improve severe or critical COVID-19 by activating ACE2 and reducing IL-6 levels.

DHEA (Prasterone) (Standard) is the analytical standard of DHEA. This product is intended for research and analytical applications. DHEA is a steroid hormone.

Pregnenolone (Standard) is the analytical standard of Pregnenolone. This product is intended for research and analytical applications. Pregnenolone (3β-Hydroxy-5-pregnen-20-one) is a powerful neurosteroid, the main precursor of various steroid hormones including steroid ketones. Pregnenolone acts as a signaling-specific inhibitor of cannabinoid CB1 receptor, inhibits the effects of tetrahydrocannabinol (THC) that are mediated by the CB1 receptors. Pregnenolone can protect the brain from cannabis intoxication. Pregnenolone is also a TRPM3 channel activator, and also can weakly activate TRPM1 channels.

Spironolactone (Standard) is the analytical standard of Spironolactone. This product is intended for research and analytical applications. Spironolactone (SC9420) is an orally active aldosterone mineralocorticoid receptor antagonist with an IC₅₀ of 24 nM. Spironolactone is also a potent antagonist of androgen receptor with an IC₅₀ of 77 nM. Spironolactone promotes autophagy in podocytes.

7-Dehydrocholesterol (Standard) is the analytical standard of 7-Dehydrocholesterol. This product is intended for research and analytical applications.7-Dehydrocholesterol is biosynthetic precursor of cholesterol and vitamin D3.

17α-Hydroxyprogesterone (Standard) is the analytical standard of 17α-Hydroxyprogesterone. This product is intended for research and analytical applications.

Medroxyprogesterone acetate (Standard) is the analytical standard of Medroxyprogesterone acetate. This product is intended for research and analytical applications.
