sulfation

Worenine (Worenin) is used in the a flurophore switched probe which aids in correction of an abasic site (AP site) caused by the removal of a damaged base in DNA.

1-Piperonylpiperazine (MDBP) undergoes demethylenation followed by methylation to form N-(4-hydroxy-3-methoxybenzyl)piperazine, with partial glucuronidation or sulfation occurring afterwards. It can alter the distribution and metabolism of 3,4-methylenedioxymethamphetamine (MDMA) in the brain and peripheral organs. Furthermore, 1-Piperonylpiperazine has the potential to inhibit the neurotoxic effects induced by MDMA.

Surfen dihydrochloride (Aminoquinuride dihydrochloride) is a potent small molecule antagonist of heparin sulfate with antibacterial and antiviral activity, and inhibits anthrax lethal factor, coagulation factor X, and lethal factor.Surfen inhibits the anticoagulant activity of both normal and low-molecular-weight heparin and inhibits heparin sulfation and heparin cleavage enzyme degradation.Surfen inhibits the blockade of FGF2 binding and signaling mediated by heparin acetylsulfate. Surfen inhibits the blockade of acetylheparin sulfate-mediated FGF2 binding and signaling.Surfen inhibits SEVI and semen-mediated enhancement of HIV type 1 infection.

Adenosine 5'-phosphosulfate (sodium salt) (APS) is a key intermediate in sulphur metabolism and a substrate for adenosine 5'-phosphosulfate kinase (APSK), which metabolises it into the high-energy sulphide donor PAPS (3'-phosphoadenosine-5'-phosphosulfate).

Phenylephrine-3-O-sulfate is metabolite of the α1A-adrenergic receptor agonist phenylephrine formed via sulfation.

Hirudin (54-65; non-sulfated) is a desulfated peptide fragment of hirudin, an anticoagulant produced byH. medicinalis.1It inhibits fibrin clot formation induced by isolated bovine thrombin with an IC50value of 3.7 μM.2 1.Niehrs, C., Huttner, W.B., Carvallo, D., et al.Conversion of recombinant hirudin to the natural form by in vitro tyrosine sulfation.

Sitagliptin N-sulfate is a phase II metabolite of the dipeptidyl peptidase 4 (DPP-4) inhibitor (-)-sitagliptin . Sitagliptin N-sulfate is formed via sulfation and has been found in rat bile following oral administration of (-)-sitagliptin.

Sulfatides are endogenous sulfoglycolipids with various biological activities in the central and peripheral nervous systems, pancreas, and immune system. They are produced from the combination of ceramide and UDP-galactose in the endoplasmic reticulum followed by sulfation in the Golgi apparatus. The ceramide portion contains variable fatty acid chain lengths, which are tissue- and pathology-dependent. Sulfatides are primarily found in the myelin sheath of oligodendrocytes and Schwann cells, with smaller chain lengths predominant during development and longer chain lengths predominant in mature cells. They accumulate in the lysosome of patients with metachromatic leukodystrophy, a disorder characterized by arylsulfatase A deficiency. Sulfatides are also located in pancreatic β-cells and inhibit insulin release from isolated rat pancreatic islet cells, suggesting a potential role in diabetes. Sulfatides can induce inflammation in glia in vitro and certain sulfatides, such as C24:1 3'-sulfo-galactosylceramide, can induce an immune response in vitro in mouse splenocytes. Sulfatides (bovine) (sodium salt) is a mixture of isolated bovine sulfatides.

Chst15-IN-1 is a selective, reversible, covalent inhibitor of the Chst15 enzyme that suppresses sulfation of chondroitin sulfate-E (CS-E) and related sulfotransferases, attenuating the inhibitory effects of chondroitin sulfate proteoglycans (CSPGs) and making it a promising candidate for promoting neuronal repair.

Indoxyl Sulfate-D5 potassium salt is intended for use as an internal standard for the quantification of indoxyl sulfate by GC- or LC-MS. Indoxyl sulfate is a uremic toxin and a metabolite of tryptophan. It is formed via sulfation of indole, an intermediate generated from tryptophan by intestinal bacteria, by the sulfotransferase (SULT) isoform 1A1 variant 2 (SULT1A1*2) in the liver. Indoxyl sulfate activates the aryl hydrocarbon receptor (AhR) in HepG2 40/6 hepatoma cells (EC50 = 12.1 nM in a reporter assay). It also inhibits the organic anion transporter (OAT) isoforms OAT1 and OAT3 (Kis = 34.2 and 74.4 µM, respectively for the rat transporters) in S2 proximal tubule cells. Indoxyl sulfate (0.2 and 1 mM) increases superoxide anion and nitric oxide levels in isolated human mononuclear blood cells. It increases serum creatinine and blood urea nitrogen (BUN) levels in the 5/6 nephrectomized rat model of chronic renal failure when administered at a dose of 50 mg/kg.

p-Cresol (Standard) is the standard substance of p-Cresol, and it is applicable for quantitative analysis, quality control, and related research in biochemical experiments. P-Cresol is a small molecular phenolic compound, which belongs to endogenous metabolites and has a certain lipophilicity, and can be highly combined with plasma protein in vivo. Its metabolism is mainly carried out through sulfation and glucuronidation, and the unbound part can be excreted in urine.

Tyrosylprotein Sulfotransferase 2 (TPST-2) is a subtype of TPST. Tyrosylprotein Sulfotransferase is a fully membrane-bound glycoprotein of the trans-Golgi network with a molecular weight of 54-50 kDa. It is found in nearly all tissues studied and catalyzes the tyrosine O-sulfation of soluble and membrane proteins passing through this compartment.

Adenosine 3'-phosphate 5'-phosphosulfate lithium serves as a cosubstrate for glycan sulfation. It can be utilized in assays involving Golgi-specific nucleotide phosphohydrolase (adenosine phosphate) 3'-phosphatase coupled with sulfotransferase, acting as a donor substrate for the transfer of the sulfonate group.

Adenosine 3'-phosphate 5'-phosphosulfate lithium is a cosubstrate used in glycoconjugate sulfation processes. It can be applied in specific Golgi phosphoadenosine 3'-phosphatase-coupled sulfotransferase assays, functioning as the donor substrate for transferring sulfate groups.
