Galactosylsphingosine

(2R,3R,4S,5R,6R)-2-{[(4E)-2-amino-3-hydroxyoctadec-4-en-1-yl]oxy}-6-(hydroxymethyl)oxane-3,4,5-triol

C24H47NO7 (461.3352)


Galactosylsphingosine (also known as psychosine), is an intermediate in the biosynthesis of cerebrosides. It is formed from the reaction of sphingosine with UDP-galactose and then reacts with fatty acid-coenzyme A to form the cerebroside. It is a galactoside metabolite of sphingosine and can function as a neurotoxin and a metabotoxin. A neurotoxin is a compound that disrupts or attacks neural cells and neural tissue. A metabotoxin is an endogenously produced metabolite that causes adverse health effects at chronically high levels. Chronically high levels of galactosylsphingosine are associated with globoid cell leukodystrophy (Krabbe disease), which is characterized by the dysfunction of galactosylceramidase. Galactosylsphingosine is a highly cytotoxic lipid capable of inducing cell death in a wide variety of cell types including oligodendrocytes. It is known to accumulate in the nervous system in the absence of galactosylceramidase. Galactosylsphingosine localizes to lipid rafts and perturbs membrane integrity. It also inhibits protein kinase C translocation to the plasma membrane (PMID: 24006512). Symptoms of Krabbe disease begin between the ages of 3 and 6 months with irritability, fevers, limb stiffness, seizures, feeding difficulties, vomiting, and slowing of mental and motor development. In the first stages of the disease, the symptoms are often mistaken with those of cerebral palsy. Other symptoms include muscle weakness, spasticity, deafness, optic atrophy, optic nerve enlargement, blindness, paralysis, and difficulty when swallowing. An intermediate in the biosynthesis of cerebrosides. It is formed by reaction of sphingosine with UDP-galactose and then itself reacts with fatty acid-Coenzyme A to form the cerebroside.

Trimeprazine

dimethyl[2-methyl-3-(10H-phenothiazin-10-yl)propyl]amine

C18H22N2S (298.1504)


Trimeprazine is only found in individuals that have used or taken this drug. It is a phenothiazine derivative that is used as an antipruritic. [PubChem]Trimeprazine competes with free histamine for binding at HA-receptor sites. This antagonizes the effects of histamine on HA-receptors, leading to a reduction of the negative symptoms brought on by histamine HA-receptor binding.

Choline phosphate

[2-(trimethylazaniumyl)ethoxy]phosphonic acid

[C5H15NO4P]+ (184.0739)


Phosphorylcholine, also known as choline phosphate or N-trimethyl-2-aminoethylphosphonate, is a member of the class of compounds known as phosphocholines. Phosphocholines are compounds containing a [2-(trimethylazaniumyl)ethoxy]phosphonic acid or derivative. Phosphorylcholine is slightly soluble (in water) and a moderately acidic compound (based on its pKa). Phosphorylcholine can be found in a number of food items such as grapefruit, lime, black cabbage, and barley, which makes phosphorylcholine a potential biomarker for the consumption of these food products. Phosphorylcholine can be found primarily in most biofluids, including urine, blood, saliva, and cerebrospinal fluid (CSF), as well as throughout most human tissues. Phosphorylcholine exists in all eukaryotes, ranging from yeast to humans. In humans, phosphorylcholine is involved in several metabolic pathways, some of which include phosphatidylcholine biosynthesis PC(13D5/9D5), phosphatidylcholine biosynthesis PC(22:5(4Z,7Z,10Z,13Z,16Z)/22:5(7Z,10Z,13Z,16Z,19Z)), phosphatidylcholine biosynthesis PC(14:0/20:1(11Z)), and phosphatidylcholine biosynthesis PC(11D5/9D5). Phosphorylcholine is also involved in few metabolic disorders, which include fabry disease, gaucher disease, and krabbe disease. Moreover, phosphorylcholine is found to be associated with alzheimers disease and multi-infarct dementia. Phosphorylcholine (abbreviated ChoP) is the hydrophilic polar head group of some phospholipids, which is composed of a negatively charged phosphate bonded to a small, positively charged choline group. Phosphorylcholine is part of platelet-activating factor; the phospholipid phosphatidylcholine as well as sphingomyelin, the only phospholipid of the membrane that is not built with a glycerol backbone. Treatment of cell membranes, like those of RBCs, by certain enzymes, like some phospholipase A2 renders the phosphorylcholine moiety exposed to the external aqueous phase, and thus accessible for recognition by the immune system. Antibodies against phosphorylcholine are naturally occurring autoantibodies that are created by CD5+/B-1 B cells and are referred to as non-pathogenic autoantibodies . Phosphorylcholine, also known as choline phosphate or CHOP, belongs to the class of organic compounds known as phosphocholines. Phosphocholines are compounds containing a [2-(trimethylazaniumyl)ethoxy]phosphonic acid or derivative. The phosphate of choline, and the parent compound of the phosphorylcholine family. Phosphorylcholine exists in all living species, ranging from bacteria to humans. Within humans, phosphorylcholine participates in a number of enzymatic reactions. In particular, phosphorylcholine can be converted into choline through its interaction with the enzyme phosphoethanolamine/phosphocholine phosphatase. In addition, phosphorylcholine can be converted into CDP-choline; which is mediated by the enzyme choline-phosphate cytidylyltransferase a. In humans, phosphorylcholine is involved in phospholipid biosynthesis. Outside of the human body, phosphorylcholine has been detected, but not quantified in several different foods, such as barley, pak choy, black radish, saskatoon berries, and acorns.

C28H38O6 (470.2668)


Withanolides, which are extracted from Withania somnifera, are employed in the treatment of arthritis and are known to be potent inhibitors of angiogenesis, inflammation and oxidative stress. Withanolides can indeed inhibit the activation of NF-κB and NF-κB-regulated gene expression, which could explain their anti-arthritic actions. W. somnifera root powder has suppressive effect on arthritis by reducing amplification and propagation of the inflammatory response, without causing any gastric damage.
