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.

Lithocholic acid (Standard) is the analytical standard of Lithocholic acid. This product is intended for research and analytical applications. Lithocholic acid is a toxic secondary bile acid that can promote intrahepatic cholestasis and promote tumorigenesis. Lithocholic acid is also a FXR antagonist and a PXR/SXR agonist.

Cholic acid (Standard) is the analytical standard of Cholic acid. This product is intended for research and analytical applications. Cholic acid is a major primary bile acid produced in the liver and usually conjugated with glycine or taurine. It facilitates fat absorption and cholesterol excretion. Cholic acid is orally active.

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.

Ursodeoxycholic acid (Standard) is the analytical standard of Ursodeoxycholic acid. This product is intended for research and analytical applications. Ursodeoxycholic acid (Ursodeoxycholate) is a secondary bile acid issued from the transformation of (cheno)deoxycholic acid by intestinal bacteria, acting as a key regulator of the intestinal barrier integrity and essential for lipid metabolism. Ursodeoxycholic acid acts as signaling molecule, exerting its effects by interacting with bile acid activated receptors, including G-protein coupled bile acid receptor 5 (TGR5, GPCR19) and the farnesoid X receptor (FXR). Ursodeoxycholic acid can be used for the research of a variety of hepatic and gastrointestinal diseases. Ursodeoxycholic acid also reduces ACE2 expression and is beneficial for reducing SARS-CoV-2 infection. Orally active.
