Lipid Metabolites

Palmitic acid is a long-chain saturated fatty acid commonly found in both animals and plants. PA can induce the expression of glucose-regulated protein 78 (GRP78) and CCAAT/enhancer binding protein homologous protein (CHOP) in in mouse granulosa cells. Palmitic acid is used to establish a cell steatosis model.

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.

Prostaglandin E2 (PGE2) is a hormone-like substance that participate in a wide range of body functions such as the contraction and relaxation of smooth muscle, the dilation and constriction of blood vessels, control of blood pressure, and modulation of inflammation.

Oleic acid (9-cis-Octadecenoic acid) is an abundant monounsaturated fatty acid. Oleic acid is a Na⁺/K⁺ ATPase activator.

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.

Glycine is an inhibitory neurotransmitter in the CNS and also acts as a co-agonist along with glutamate, facilitating an excitatory potential at the glutaminergic N-methyl-D-aspartic acid (NMDA) receptors. Glycine is orally active. Glycine inhibits the membrane aggregation of NINJ1 and prevents plasma membrane rupture during cell death. Glycine can be used to study cell protection, cancer, neurological diseases, and angiogenesis.

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

Arachidonic acid (Immunocytophyt) is a polyunsaturated omega-6 fatty acid and a major constituent of biomembranes. Arachidonic acid also acts as the substrate for various lipid mediators, such as prostaglandins (PGs). Arachidonic acid improves cognitive response and cardiovascular function.

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.

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.

D-Glucose is the naturally occurring form of glucose and the most abundant monosaccharide. D-Glucose is a critical components of the general metabolism, and serve as critical signaling molecules in relation to both cellular metabolic status and biotic or abiotic stress response.

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

Taurine, a sulphur-containing amino acid and an organic osmolyte involved in cell volume regulation, provides a substrate for the formation of bile salts, and plays a role in the modulation of intracellular free calcium concentration. Taurine has the ability to activate autophagy in adipocytes.

Linoleic acid is a common polyunsaturated (PUFA) found in plant-based oils, nuts and seeds. Linoleic acid is a part of membrane phospholipids, and functions as a structural component to maintain a certain level of membrane fluidity of the transdermal water barrier of the epidermis. Linoleic acid induces red blood cells and hemoglobin damage via oxidative mechanism .

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.

Sphingosine-1-phosphate (S1P) is an agonist of S1P_1-5 receptors and a ligand of GPR3, GPR6 and GPR12. Sphingosine-1-phosphate is an intracellular second messenger and mobilizes Ca²⁺ as an extracellular ligand for G protein-coupled receptors. Sphingosine-1-phosphate is an important lipid mediator generated from Sphingomyelin (HY-113498) or other membrane phospholipids. Sphingosine-1-phosphate stimulates the DNA synthesis, cell proliferation and migration.

Eicosapentaenoic Acid (EPA) is an orally active Omega-3 long-chain polyunsaturated fatty acid (ω-3 LC-PUFA). Eicosapentaenoic Acid exhibits a DNA demethylating action that promotes the re-expression of the tumor suppressor gene CCAAT/enhancer-binding protein δ (C/EBPδ). Eicosapentaenoic Acid activates RAS/ERK/C/EBPβ pathway through H-Ras intron 1 CpG island demethylation in U937 leukemia cells. Eicosapentaenoic Acid can promote relaxation of vascular smooth muscle cells and vasodilation.

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