Sterol Lipids

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.

Medroxyprogesterone acetate is a widely used synthetic steroid by its interaction with progesterone, androgen and glucocorticoid receptors.

Methylprednisolone (U 7532) 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.

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.

Taurochenodeoxycholic acid (12-Deoxycholyltaurine) is one of the main bioactive substances of animals' bile acid. Taurochenodeoxycholic acid induces apoptosis and shows obvious anti-inflammatory and immune regulation properties.

Glycochenodeoxycholic acid (Chenodeoxycholylglycine) is a relatively toxic bile salt generated in the liver from chenodeoxycholic acid and glycine. Glycochenodeoxycholic acid inhibits Autophagosome formation and impairs lysosomal function by inhibiting lysosomal proteolysis and increasing lysosomal pH in human normal liver cells, leading to the Apoptosis of human hepatocyte cells. Glycochenodeoxycholic acid induces stemness and chemoresistance via activating STAT3 signaling pathway in hepatocellular carcinoma cells (HCC). Glycochenodeoxycholic acid is promising for research in the field of cholestasis desease, hepatocellular carcinoma and primary sclerosing cholangitis (PSC).

Prednisone (Adasone) is a corticosteroid agent with anti-inflammatory and immunosuppressive effects that can be used to study diseases related to systemic lupus erythematosus.

Tauroursodeoxycholate (Tauroursodeoxycholic acid; TUDCA) sodium is an endoplasmic reticulum (ER) stress inhibitor. Tauroursodeoxycholate significantly reduces expression of apoptosis molecules, such as caspase-3 and caspase-12. Tauroursodeoxycholate also inhibits ERK.

Deoxycholic acid sodium salt (sodium deoxycholate), a bile acid, is a by-product of intestinal metabolism, that activates the G protein-coupled bile acid receptorTGR5.

Aldosterone is the primary mineralocorticoid. Aldosterone is a steroid hormone, and it is synthesized and secreted in response to renin-angiotensin system activation (RAS) or high dietary potassium by the zona glomerulosa (ZG) of the adrenal cortex. Aldosterone activity is dependent by the binding and activation of the cytoplasmic/nuclear mineralocorticoid receptor (MR) at cellular level.

Veratridine (3-Veratroylveracevine) is a plant neurotoxin, a voltage-gated sodium channels (VGSCs) agonist. Veratridine inhibits the peak current of Nav1.7, with an IC₅₀ of 18.39 µM. Veratridine regulates sodium ion channels mainly by activating sodium ion channels, preventing channel inactivation and increasing sodium ion flow.

Withaferin A is a steroidal lactone isolated from Withania somnifera, inhibits NF-kB activation and targets vimentin, with potent antiinflammatory and anticancer activities. Withaferin A is an inhibitor of endothelial protein C receptor (EPCR) shedding.

Dexamethasone (Hexadecadrol) Water Soluble is a water-soluble form of Dexamethasone (HY-14648). Dexamethasone is a glucocorticoid receptor agonist, apoptosis inducer, and a common disease inducer in experimental animals. It can be used to construct models of muscle atrophy, hypertension, and depression. Dexamethasone can inhibit the production of inflammatory miRNA-155 exosomes in macrophages and significantly reduce the expression of inflammatory factors in neutrophils and monocytes. Dexamethasone also has the potential to be used in COVID-19 research.(Sale size is the weight of dexamethasone)

Estradiol benzoate (β-Estradiol 3-benzoate) is a HBx protein inhibitor and inhibits androgen and hepatitis B virus (HBV) transcription, replication. Estradiol benzoate shows antifertility effects, anti- Toxoplasma gondii activity and can improve memory behavior of Ovariectomy (Ovx) female mice.

7-Ketocholesterol is an oxidation product of cholesterol, widely present in atherosclerotic plaques, and has a stronger atherogenic effect than cholesterol. 7-Ketocholesterol can inhibit the rate-limiting enzymes involved in bile acid and cholesterol synthesis, such as cholesterol 7α-hydroxylase and HMG-CoA reductase. 7-Ketocholesterol exhibits pro-inflammatory effects both in vivo and in vitro and can induce cell apoptosis (apoptosis).

Taurocholic acid sodium (Sodium taurocholate) has marked bioactive effects such as an inhibitory potential against hepatic artery ligation induced biliary damage by upregulation of VEGF-A expression. Taurocholic acid sodium has immunoregulation effect.

Spironolactone is an aldosterone antagonist that acts on the aldosterone mineralocorticoid receptor (IC₅₀=24 nM) and androgen receptor (IC₅₀=77 nM), promotes podocyte autophagy and regulates pain. Spironolactone improves hypertension-related vascular hypertrophy and remodeling by reducing angiotensin II (Ang II)-induced inflammation, reduces aldosterone-induced vascular and soft tissue calcification through PIT1-dependent signaling, and alleviates vascular dysfunction in type II diabetic mice by reducing oxidative stress and restoring NO/GC signaling; at low concentrations, it and its metabolites can interfere with aldosterone biosynthesis in the adrenal cortex and inhibit voltage-dependent Ca²⁺ channels to exert antihypertensive effects.

Calcifediol (25-hydroxy Vitamin D3) is an effective VDR ligand and VD supplement. Calcifediol is a prohormone of the vitamin D endocrine system (VDES) and is hydroxylated in the liver to produce the active form, calcitriol. Calcifediol can rapidly increase serum VD levels.

2-Methoxyestradiol (2-ME2), an orally active endogenous metabolite of 17β-estradiol (E2), is an apoptosis inducer and an angiogenesis inhibitor with potent antineoplastic activity. 2-Methoxyestradiol also destablize microtubules. 2-Methoxyestradio, also a potent superoxide dismutase (SOD) inhibitor and a ROS-generating agent, induces autophagy in the transformed cell line HEK293 and the cancer cell lines U87 and HeLa.

Dioscin (CCRIS 4123; Collettiside III) is a natural plant-derived steroidal saponin that has good anti-cancer activity against a variety of cancer cells. Dioscin causes DNA damage and induces apoptosis in HeLa and SiHa cells. Dioscin regulates ROS-mediated DNA damage and mitochondrial signaling pathways, exerting anticancer activity.
