General description

ARL 67156, a nucleotide/ATP analog is a competitive inhibitor of CD39. This ecto-ATPase inhibitor is presumed to be metabolically stable in biological studies due to its β, γ-dibromomethylene bridge.
ARL-67156 preferentially inhibits the degradation of ADP compared to the degradation of ATP in the murine colon. It is commonly employed to inhibit ATP hydrolysis in tissue preparations.

Application

ARL 67156 trisodium salt hydrate has been used:
  • to prevent ATP degradation during cerebrospinal fluid extraction
  • as an ATPase inhibitor in ATP quantification assay for preventing ATP degradation in cytoplasm and mitochondrion
  • as an ecto-ATPase inhibitor to treat cancer cells for ATP release assay

Biochem/physiol Actions

ecto-ATPase inhibitor; prevents metabolism of P2 purinoceptor agonists.

1. FPL 67156 (6-N,N-diethyl-beta, gamma-dibromomethylene-D-ATP), is a newly synthesized analogue of ATP. 2. In a rabbit isolated tracheal epithelium preparation, measuring P2U-purinoceptor-dependent chloride secretion, FPL 67156 was discovered to potentiate the responses to UTP but not those to ATP-gamma-S. UTP

ARL 67156, 6-N,N-Diethyl-D-beta-gamma-dibromomethylene adenosine triphosphate, originally named FPL 67156, is the only commercially available inhibitor of ecto-ATPases. Since the first report on this molecule, various ectonucleotidases responsible for the hydrolysis of ATP at the cell surface have been cloned and

The influence of enzymatic degradation on the neurotransmitter actions of ATP was studied using the ecto-ATPase inhibitor 6-N,N-diethyl-D-beta,gamma-dibromomethyleneATP (ARL 67156). Field stimulation of the parasympathetic nerves innervating guinea-pig urinary bladder muscle strips (1-8 Hz for 20 s) produced characteristic biphasic
