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.

Nucleoside triphosphate diphosphohydrolase1 (NTPDase1, CD39) inhibitors have potential as novel drugs for the (immuno)therapy of cancer. They increase the extracellular concentration of immunostimulatory ATP and reduce the formation of AMP, which can be further hydrolyzed by ecto-5'-nucleotidase (CD73) to immunosuppressive

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

Caspase-4 is an intracellular sensor for cytosolic bacterial lipopolysaccharide (LPS) and underlies infection-elicited pyroptosis. It is unclear whether and how caspase-4 detects host-derived factors to trigger pyroptosis. Here we show that mitochondrial permeability transition (MPT) activates caspase-4 by promoting the
