Pyridoxine 5'-phosphate

5-Hydroxy-6-methyl-3,4-pyridinedimethanol alpha( 3)-(dihydrogen phosphate)

C8H12NO6P (249.0402222)

Pyridoxine phosphate, also known as pyridoxine 5-phosphoric acid or pyridoxine 5-(dihydrogen phosphate), is a member of the class of compounds known as pyridoxine-5-phosphates. Pyridoxine-5-phosphates are pyridoxines that carry a phosphate group at the 5-position. Pyridoxine phosphate is slightly soluble (in water) and a moderately acidic compound (based on its pKa). Pyridoxine phosphate can be found primarily in blood. Within the cell, pyridoxine phosphate is primarily located in the cytoplasm (predicted from logP). Pyridoxine phosphate exists in all living species, ranging from bacteria to humans. In humans, pyridoxine phosphate is involved in the vitamin B6 metabolism. Pyridoxine phosphate is also involved in hypophosphatasia, which is a metabolic disorder. Moreover, pyridoxine phosphate is found to be associated with obesity. Pyridoxine 5-phosphate is a substrate for Pyridoxine-5-phosphate oxidase and Pyridoxal kinase.

Norepinephrine sulfate

{4-[(1R)-2-amino-1-hydroxyethyl]-2-hydroxyphenyl}oxidanesulphonic acid

C8H11NO6S (249.0307066)

Plasma norepinephrine sulfate increases after sympathetic nervous system activation by an exhausting incremental exercise test and remain elevated up to 2 h after exercise. (PMID: 8330610). Human platelets contribute to the formation of plasma norepinephrine sulfate by norepinephrine uptake, intraplatelet sulfoconjugation and release of norepinephrine sulfate. (PMID: 7968241). Higher concentrations of norepinephrine sulfate in portal venous than arterial plasma indicate substantial production of norepinephrine by mesenteric organs. (PMID: 8627312). Intravenously infused norepinephrine is sulfoconjugated in humans, indicating that a major part of NE is sulfoconjugated in blood or at sites easily accessible from blood. (PMID: 12020748). Plasma norepinephrine sulfate increases after sympathetic nervous system activation by an exhausting incremental exercise test and remain elevated up to 2 h after exercise. (PMID: 8330610)

Phaclofen

beta-(4-Chlorophenyl)-3-aminopropylphosphonic acid

C9H13ClNO3P (249.0321548)

D018377 - Neurotransmitter Agents > D018682 - GABA Agents > D018756 - GABA Antagonists Phaclofen is a selective GABAB receptor antagonist. Phaclofen is a peripheral and central baclofen antagonist. Phaclofen maybe a potential compound in determining the physiological significance of central and peripheral bicuculline-insensitive receptors with which GABA and (-)-baclofen interact[1][2].
