ARL 67156

Uses

ARL 67156 Trisodium Salt acts as an ecto-ATPase inhibitor used to aid in distinguishing the function of ATP and its hydrolysis product adenosine in vivo.

Biological Activity

arl 67156 trisodium salt is a selective inhibitor of ecto-atpase. also, fpl 67156 is a weak agonist of p2u-purinoceptors and weak antagonist of p2t- and p2x-purinoceptors [1].ecto-atpase is an integral membrane protein that catalyzes the hydrolysis of extracellular atp to adp and inorganic phosphate.arl 67156 trisodium salt is a selective ecto-atpase inhibitor. in the human blood cell assay, arl 67156 inhibited atp degradation with pic50 value of 4.62. in the rabbit ear artery, arl 67156 30 μm-1 mm) increased the contractile effects of atp and inhibited ecto-atpase with pki value of 5.2 [1]. in the guinea-pig vas deferens, arl 67156 (5-100 μm) significantly increased neurogenic contract response to nerve stimulation in a concentration-dependent way, which was due to potentiation of the action of atp [2]. in hek 293t or cos-7 cells transfected with human npp1, npp3, ntpdase1, 2, 3 or 8, arl 67156 (50-100 μm) competitively inhibited human npp1, ntpdase1 and ntpdase3 with ki values of 12, 11 and 18 μm, respectively [3].in warfarin-induced mineralization rat model, arl67156 inhibited mineralization of the aortic valve/aorta and prevented aortic stenosis by the inhibition of apoptosis. also, arl67156 normalized the level of pakt, which was involved in the survival pathway [4].
