A2P5P
A2P5P (2',5'-ADP) is a P2Y1 purinergic receptor antagonist and ribonuclease inhibitor. A2P5P selectively blocks Adenosine 5'-diphosphate (ADP) (HY-W010918)-induced P2Y1-mediated phospholipase C activation and intracellular Ca2+ mobilization, is selective for P2Y2/P2Y4 with no significant effect on P2Y11, thereby inhibiting platelet shape change, aggregation, actin (Actin) polymerization, early αIIbβ3 activation, granule centralization, filopodia formation, and serotonin secretion, without affecting Thrombin (MW 37kDa) (HY-114164)-induced aggregation. A2P5P also binds to the catalytic site of RNase A (HY-129046), EDN, and ECP, inhibiting ribonucleolytic activity through water-mediated hydrogen bonds and transglycosidic/ribose conformations, stabilizing the inactive catalytic histidine conformation. A2P5P can be used for research on platelet function and ribonuclease-related studies.

In Vitro
A2P5P (100 μM) strongly inhibits ADP-induced Ca2+ mobilization in HTC rat hepatoma cells[1].
A2P5P (30 s) does not significantly modulate IP3 accumulation in 1321N1 cells expressing human P2Y11, whether tested alone or together with 100 μM ATP[2].
A2P5P (15 min) does not significantly modulate Cyclic AMP (HY-B1511)
accumulation in CHO-K1 cells expressing human P2Y11, whether tested alone or together with 100 μM ATP[2].
A2P5P (1 mM) abolishes ADP-induced aggregation in washed human platelets and strongly inhibits aggregation and secretion induced by low concentrations of U46619 (HY-108566) or low concentrations of thrombin, while having no effect on high concentrations of U46619 or high concentrations of thrombin[4].
A2P5P (1 mM; 10-45 s) prevents ADP-induced shape change and granule centralization in washed human platelets, inhibits filopodia formation induced by low concentrations of U46619, and partially prevents shape change induced by low concentrations of thrombin[4].
A2P5P (1 mM) eliminates ADP-induced F-actin assembly in washed human platelets and reduces the F-actin increase triggered by low concentrations of U46619 or low concentrations of thrombin[4].
A2P5P (1 mM; 2-30 s) abolishes ADP- and low-concentration U46619-induced cytoskeletal translocation of cdc42, rac1, and rhoA in washed human platelets[4].
A2P5P (1 mM; 3 s) abolishes ADP-induced early activation of αIIbβ3 in washed human platelets[4].
A2P5P (100 µM; 24 h) blocks 2-MeSADP-induced AChE promoter activity in 10 DIV rat cortical neurons[5].
A2P5P (1 mM; 3 min) reduces ADP-induced platelet aggregation in human platelet-rich plasma by 58.3%[6].
A2P5P (1 mM; 3 min) inhibits ADP-induced calcium influx in human platelet-rich plasma[6].
A2P5P (at a 30-fold molar excess relative to 10 µM ADP) inhibits P2Y1-mediated intracellular calcium mobilization in human platelets, with complete inhibition at a 30-fold molar excess relative to 10 µM ADP[7].
A2P5P (300 µM) inhibits ADP- and 2-MeSADP (HY-108648A)-induced morphological changes in Aspirin (HY-14654)-treated human platelets, with complete inhibition at 300 µM[7].
A2P5P (200 µM; 0.5 min before ADP) does not block ADP-induced inhibition of adenylyl cyclase in human platelets, indicating that P2Y1 antagonism does not prevent this P2TAC-mediated response[7].
A2P5P (100 µM) inhibits ADP-induced rat platelet aggregation and morphological changes, with a pA value of 5.6 and a Schild slope of 0.74[8].
A2P5P (100 µM) eliminates ADP-induced elevation of [Ca2+]i in rat platelets[8].
A2P5P (100 µM) does not affect basal or PGE1-stimulated cAMP, nor does it reverse ADP-induced adenylyl cyclase inhibition in rat platelets[8].
A2P5P (5 min) displaces residual [33P]2MeSADP binding on rat platelets treated with Clopidogrel (HY-15283) with a Ki of 9.5 µM[8].
A2P5P (50 mM; at least 4 h) binds to bovine pancreatic RNase A within the asymmetric unit in two different modes, with its 2′- or 5′-phosphate group anchored at the P1 subsite, while the adenine occupies different B2 positions[9].
