Adenosine 5′′-O-thiomonophosphate (5′-AMPS) is a 5′-O-thiophosphate which along with adenosine 5′-O-(2-thiodiphosphate) and adenosine 5′-O-(3-thiotriphosphate) can act as inhibitors of phosphohydrolases. AMPS is a substrate for smooth muscle endothelial ecto-5′-nucleotidase. 5′APMS is a stimulator of 5-lipoxygenase activity of rat polymorphonuclear (PMN) leukocytes. Histidine triad nucleotide-binding protein 1 (HINT-1) phosphoramidase transforms nucleoside 5′-O-phosphorothioates such as 5′-AMPS to nucleoside 5′-O-phosphates.

Nucleoside 5'-O-phosphorothioates are formed in vivo as primary products of hydrolysis of oligo(nucleoside phosphorothioate)s (PS-oligos) that are applied as antisense therapeutic molecules. The biodistribution of PS-oligos and their pharmacokinetics have been widely reported, but little is known about their subsequent

We compared the properties of the ectonucleotidases (nucleoside triphosphatase, EC 3.6.1.15; nucleoside diphosphatase, EC 3.6.1.6; 5'-nucleotidase, EC 3.1.3.5) in intact pig aortic smooth-muscle cells in culture with the properties that we previously investigated for ectonucleotidases of aortic endothelial cells [Cusack

The stable nucleotide analog guanosine 5'-O-(3-thiotriphosphate) (GTP gamma S) was found to be a very potent activator of 5-lipoxygenase in cell-free preparations from rat polymorphonuclear (PMN) leukocytes, causing a 10-fold stimulation of arachidonic acid oxidation at concentrations as low as
Adenosine 5'-phosphorothioate. A nucleotide analog that is a substrate, competitive inhibitor, or regulator of some enzymes that interact with adenosine 5'-phosphate.

Adenosine diphosphatase (ADPase) activity and ATPase activity were assayed in rat liver mitochondria and outer mitochondrial membrane preparations with [beta-32P]ADP and [gamma-32P]ATP as substrates. Inhibition studies were performed with the mitochondrial ATPase inhibitor oligomycin and the adenine nucleotide transport inhibitor
