Sterol Lipids

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 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 potential for use in COVID-19 research.

Hydrocortisone (Cortisol) is a steroid hormone or glucocorticoid secreted by the adrenal cortex.

Estradiol (β-Estradiol) is a steroid hormone and the major female sex hormone. Estradiol can up-regulate the expression of neural markers of human endometrial stem cells (hEnSCs) and promote their neural differentiation. Estradiol can be used for the research of cancers, neurodegenerative diseases and neural tissue engineering.

Digitonin, a glycoside obtained from Digitalis purpurea, could increase cell permeability by binding to cholesterol molecules and reduce tumor growth. Digitonin is an natural detergent.

Cholesterol (from animal) 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 (from animal) 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 (from animal) is also an endogenous estrogen-related receptor α (ERRα) agonist.

Trihydroxycoprostane (THCP) is a polyhydroxysterane compound with a 5β configuration. ITrihydroxycoprostane acts as a key intermediate in the biosynthesis of bile acids from cholesterol and also serves as an important sterol metabolite generated by host-gut microbiota interactions. Trihydroxycoprostane can be used for mechanistic studies of diseases such as non-alcoholic fatty liver disease, inflammatory bowel disease, and bile acid metabolism disorders.

Schottenol is a natural steroid.

5α-Dihydrocortisol (5α-DHF), a metabolite of Hydrocortisone (Cortisol) (HY-N0583), is a steroid hormone. 5α-Dihydrocortisol can enhance the mineralocorticoid activity of aldosterone.

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.

Calcipotriol is a synthetic VitD₃ analogue with a high affinity for the vitamin D receptor.

Calcitriol is the most active metabolite of vitamin D and also a vitamin D receptor (VDR) agonist.

DHEA (Prasterone) is one of the most abundant steroid hormones. DHEA (Prasterone) mediates its action via multiple signaling pathways involving specific membrane receptors and via transformation into androgen and estrogen derivatives (e.g., androgens, estrogens, 7α and 7β DHEA, and 7α and 7β epiandrosterone derivatives) acting through their specific receptors.

Wortmannin (SL-2052; KY-12420) is a potent, selective and irreversible PI3K inhibitor with an IC₅₀ of 3 nM. Wortmannin also blocks autophagy formation, and potently inhibits Polo-like kinase 1 (PlK1) and Plk3 with IC₅₀s of 5.8 and 48 nM, respectively.

Progesterone is a steroid hormone that regulates the menstrual cycle and is crucial for pregnancy.

Cholesterol Water Soluble is a major sterol in mammals, constituting 20-25% of the structural composition of the plasma membrane. The plasma membrane is highly permeable to water but relatively impermeable to ions and protons. Cholesterol Water Soluble plays an important role in determining the fluidity and permeability characteristics of membranes and the function of transporters and signaling proteins. Cholesterol Water Soluble is also an endogenous estrogen-related receptor alpha (ERRα) agonist. Cholesterol Water Soluble can be used to study the effects of cholesterol on potassium currents in inner hair cells.

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

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.

Chenodeoxycholic Acid is a hydrophobic primary bile acid that activates nuclear receptors (FXR) involved in cholesterol metabolism.

25-Hydroxycholesterol (25-OHC) is a metabolite of cholesterol that is produced and secreted by macrophages in response to Toll-like receptor (TLR) activation. 25-hydroxycholesterol is a potent (EC₅₀≈65 nM) and selective suppressor of IgA production by B cells.

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