Adenosine 5'-phosphosulfate is an ATP and sulfate competitive inhibitor of ATP sulfurylase in humans, S. cerevisiae, and P. chrysogenum (Ki = 18, 2500, and 1500 nM, respectively). Adenosine 5'-phosphosulfate also inhibits human adenosine 5'-phosphosulfate kinase (Ki = 47.5 μM) to prevent sulfation.

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 powerful, reversible, covalent inhibitor of the Chst15 enzyme. It effectively suppresses the sulfation levels of chondroitin sulfate-E (CS-E) and other closely related sulfotransferases responsible for glycosaminoglycans (GAGs) synthesis. Acting as a selective sulfotransferase inhibitor, Chst15-IN-1 can attenuate the inhibitory actions of chondroitin sulfate proteoglycans (CSPGs), making it a promising candidate for enhancing neuronal repair.

Indoxyl sulfate-d5 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) 是 p-Cresol 的标准品，适用于定量分析、质量控制及生化实验等相关研究。p-Cresol 是一种部分亲脂性部分，在正常条件下与血浆蛋白（接近 100%）强烈结合。对甲酚通过结合代谢，主要是硫酸化和葡萄糖醛酸化，但未结合的对甲酚至少部分通过尿液去除。

Tyrosylprotein Sulfotransferase 2 (TPST-2) 是 TPST 的一个亚型。Tyrosylprotein Sulfotransferase 是一种 54-50 kDa 的反式高尔基网络的完整膜糖蛋白，已在几乎所有被研究的组织中发现，催化通过该隔室的可溶性蛋白和膜蛋白的酪氨酸 O-硫酸化。
