Stimulation of the P2Y1 receptor up-regulates nucleoside-triphosphate diphosphohydrolase-1 in human retinal pigment epithelial cells.[Pubmed:17626796]

J Pharmacol Exp Ther. 2007 Oct;323(1):157-64.

Stimulation of receptors for either ATP or adenosine leads to physiologic changes in retinal pigment epithelial (RPE) cells that may influence their relationship with the adjacent photoreceptors. The ectoenzyme nucleoside-triphosphate diphosphohydrolase-1 (NTPDase1) catalyzes the dual dephosphorylation of ATP and ADP to AMP. Although NTPDase1 can consequently control the balance between ATP and adenosine, it is unclear how its expression and activity are regulated. Classic negative feedback theory predicts an increase in enzyme activity in response to enhanced exposure to substrate. This study asked whether exposure to ATP increases NTPDase1 activity in RPE cells. Although levels of NTPDase1 mRNA and protein in cultured human ARPE-19 cells were generally low under control conditions, exposure to slowly hydrolyzable ATPgammaS led to a time-dependent increase in NTPDase1 mRNA that was accompanied by a rise in levels of the functional 78-kDa protein. Neither NTPDase2 nor NTPDase3 mRNA message was elevated by ATPgammaS. The ATPase activity of cells increased in parallel, indicating the up-regulation of NTPDase1 was functionally relevant. The up-regulation of NTPDase1 protein was partially blocked by P2Y1 receptor inhibitors MRS2179 (N6-methyl-2'-deoxyadenosine-3',5'-bisphosphate) and MRS2500 [2-iodo-N6-methyl-(N)-methanocarba-2'-deoxyadenosine 3',5'-bisphosphate] and increased by P2Y1 receptor agonist MRS2365 [(N)-methanocarba-2MeSADP]. In conclusion, prolonged exposure to extracellular ATPgammaS increased NTPDase1 message and protein levels and increased ecto-ATPase activity. This up-regulation reflects a feedback circuit, mediated at least in part by the P2Y1 receptor, to regulate levels of extracellular purines in subretinal space. NTPDase1 levels may thus serve as an index for increased extracellular ATP levels under certain pathologic conditions, although other mechanisms could also contribute.

Synthesis, biological activity, and molecular modeling of ribose-modified deoxyadenosine bisphosphate analogues as P2Y(1) receptor ligands.[Pubmed:10715151]

J Med Chem. 2000 Mar 9;43(5):829-42.

The structure-activity relationships of adenosine-3', 5'-bisphosphates as P2Y(1) receptor antagonists have been explored, revealing the potency-enhancing effects of the N(6)-methyl group and the ability to substitute the ribose moiety (Nandanan et al. J. Med. Chem. 1999, 42, 1625-1638). We have introduced constrained carbocyclic rings (to explore the role of sugar puckering), non-glycosyl bonds to the adenine moiety, and a phosphate group shift. The biological activity of each analogue at P2Y(1) receptors was characterized by measuring its capacity to stimulate phospholipase C in turkey erythrocyte membranes (agonist effect) and to inhibit its stimulation elicited by 30 nM 2-methylthioadenosine-5'-diphosphate (antagonist effect). Addition of the N(6)-methyl group in several cases converted pure agonists to antagonists. A carbocyclic N(6)-methyl-2'-deoxyadenosine bisphosphate analogue was a pure P2Y(1) receptor antagonist and equipotent to the ribose analogue (MRS 2179). In the series of ring-constrained methanocarba derivatives where a fused cyclopropane moiety constrained the pseudosugar ring of the nucleoside to either a Northern (N) or Southern (S) conformation, as defined in the pseudorotational cycle, the 6-NH(2) (N)-analogue was a pure agonist of EC(50) 155 nM and 86-fold more potent than the corresponding (S)-isomer. The 2-chloro-N(6)-methyl-(N)-methanocarba analogue was an antagonist of IC(50) 51.6 nM. Thus, the ribose ring (N)-conformation appeared to be favored in recognition at P2Y(1) receptors. A cyclobutyl analogue was an antagonist with IC(50) of 805 nM, while morpholine ring-containing analogues were nearly inactive. Anhydrohexitol ring-modified bisphosphate derivatives displayed micromolar potency as agonists (6-NH(2)) or antagonists (N(6)-methyl). A molecular model of the energy-minimized structures of the potent antagonists suggested that the two phosphate groups may occupy common regions. The (N)- and (S)-methanocarba agonist analogues were docked into the putative binding site of the previously reported P2Y(1) receptor model.

Competitive and selective antagonism of P2Y1 receptors by N6-methyl 2'-deoxyadenosine 3',5'-bisphosphate.[Pubmed:9630335]

Br J Pharmacol. 1998 May;124(1):1-3.

The antagonist activity of N6-methyl 2'-deoxyadenosine 3',5'-bisphosphate (N6MABP) has been examined at the phospholipase C-coupled P2Y1 receptor of turkey erythrocyte membranes. N6MABP antagonized 2MeSATP-stimulated inositol phosphate hydrolysis with a potency approximately 20 fold greater than the previously studied parent molecule, adenosine 3',5'-bisphosphate. The P2Y1 receptor antagonism observed with N6MABP was competitive as revealed by Schild analysis (pK(B) = 6.99 +/- 0.13). Whereas N6MABP was an antagonist at the human P2Y1 receptor, no antagonist effect of N6MABP was observed at the human P2Y2, human P2Y4 or rat P2Y6 receptors.
