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.

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.

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.

Beta-Sitosterol (purity>98%) 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.

Stigmasterol is an orally acitve, immunomodulatory agent with anti-inflammatory and neuroprotective effect, as well as able to cross the blood-brain barrier. Stigmasterol activates AMPK, which in turn inhibits NF-κB and NLRP3 signaling pathways, reduces microglia-mediated neuroinflammation, and alleviates cognitive impairment and Alzheimer's disease. Stigmasterol regulates M1/M2 polarization of microglia through the TLR4/ NF-κB pathway, thereby reducing neuropathic pain. Stigmasterol can be used for neurodegenerative diseases, inflammatory diseases, and pain management, among others.

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

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.
