Abstract
Metastatic melanoma is a very aggressive skin cancer. Platelets are constituents of the tumor microenvironment and, when activated, contribute to cancer progression, especially metastasis and inflammation. P2Y12 is an adenosine diphosphate receptor that triggers platelet activation. Inhibition of P2Y12 by clopidogrel bisulfate (CB) decreases platelet activation, which is also controlled by the extracellular concentration and the metabolism of purines by purinergic enzymes. We evaluated the effects of CB on the viability and proliferation of cultured B16-F10 cells. We also used a metastatic melanoma model with C57BL-6 mice to evaluate cancer development and purine metabolism modulation in platelets. B16-F10 cells were administered intraperitoneally to the mice. Two days later, the animals underwent a 12-day treatment with CB (30 mg/kg by gavage). We have found that CB reduced cell viability and proliferation in B16-F10 culture in 72 h at concentrations above 30 µm. In vivo, CB decreased tumor nodule counts and lactate dehydrogenase levels and increased platelet purine metabolism. Our results showed that CB has significant effects on melanoma progression.

Cell Mol Biol Lett 2018; 23:15. [PMID: 29713353 PMCID: PMC5905151 DOI: 10.1186/s11658-018-0082-4] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2017] [Accepted: 04/09/2018] [Indexed: 01/01/2023] Open
Abstract
Background The leaves of Annona purpurea have yielded several alkaloids with anti-aggregation activities against rabbit platelets. This is promising in the search for agents that might act against platelets and reduce the incidence of cardiovascular diseases. Since significant differences in platelet function have been reported between human and animal platelets, a study focusing on the effect of A. purpurea extracts against human platelet activation is necessary. Methods The compounds in an A. purpurea ethanolic extract underwent bio-guided fractionation and were used for in vitro human platelet aggregation assays to isolate the compounds with anti-platelet activity. The bioactive compounds were identified by spectroscopic analysis. Additional platelet studies were performed to characterize their action as inhibitors of human platelet activation. Results The benzylisoquinoline alkaloid norpurpureine was identified as the major anti-platelet compound. The IC50 for norpurpureine was 80 μM against platelets when stimulated with adenosine 5′-diphosphate (ADP), collagen and thrombin. It was pharmacologically effective from 20 to 220 μM. Norpurpureine (220 μM) exhibited its in vitro effectiveness in samples from 30 healthy human donors who did not take any drugs during the 2 weeks prior to the collection. Norpurpureine also gradually inhibited granule secretion and adhesion of activated platelets to immobilized fibrinogen. At the intra-platelet level, norpurpureine prevented agonist-stimulated calcium mobilization and cAMP reduction. Structure–activity relationship analysis indicates that the lack of a methyl group at the nitrogen seems to be key in the ability of the compound to interact with its molecular target. Conclusion Norpurpureine displays a promising in vitro pharmacological profile as an inhibitor of human platelet activation. Its molecular target could be a common effector between Ca2+ and cAMP signaling, such as the PLC-PKC-Ca2+ pathway and PDEs. This needs further evaluation at the protein isoform level.

Abstract
Many clinical trials have demonstrated the beneficial effects of soybean (Glycine max) on general cardiovascular health. Among a variety of soybeans, black soybean is known to display diverse biological activities superior to those of yellow and green soybeans, such as in antioxidant, anti-inflammatory and anticancer activities. However, few studies have been directed on the effect of black soybean on cardiovascular function. In this study, we aimed to investigate the effect of black soybean extract (BB) on platelet activation, a key contributor to thrombotic diseases. In freshly isolated human platelets, BB has shown potent inhibitory activity on collagen-induced platelet aggregation, while yellow soybean extract had marginal activity only. BB also attenuated serotonin secretion and P-selectin expression, which are important factors for the platelet-tissue interaction along with thromboxane A(2) formation. These in vitro results were further confirmed in an ex vivo platelet aggregation measurement and in vivo venous thrombosis model where oral administration of BB reduced collagen-induced platelet aggregation and FeCl(3)-induced thrombus formation significantly. A potential active ingredient for antiplatelet effects of BB was isolated and identified to be adenosine through bioassay-directed fractionation and NMR and ESI-MS analyses. These results indicate that black soybean can be a novel dietary supplement for the prevention of cardiovascular risks and the improvement of blood circulation.

Abstract
Ischemia and reperfusion injury is a pathologic process with serious consequences, arising due to interruption of arterial blood flow. Restored blood flow achieved after the ischemic period causes formation of oxygen radicals by activation of a variety of substances and systems. In this study, we investigated the effect of clopidogrel, an antithrombocyte agent, on tissue nitric oxide (NO) levels in an experimental ischemia reperfusion model. For this purpose, 6 hours of ischemia and 4 hours of subsequent reperfusion were applied to the right lower extremities of the subjects. Clopidogrel therapy was started in one of these groups 10 days before the process (study group). NO levels were measured in all groups in the muscle, lung, and liver tissues, and in plasma. Lung, plasma, and liver NO measurement values had statistically significant differences among the groups. There was no statistically significant difference in the measurements made on the muscle tissue. Clopidogrel, which has previously been reported to be suitable to be used as a preventive agent of ischemia reperfusion damage, has had a reducing effect on the NO levels in tissues in the ischemia reperfusion model created in our present study.

Abstract
Clopidogrel is an antiplatelet drug that belongs to the group of thienopyridines. Because of its main mechanism of action most studies of clopidogrel have centered on the platelet ADP pathway. The aim of the present study was to compare the effects of clopidogrel, ticlopidine, and aspirin, on platelet activation by collagen (the main inducer of platelet activation in vivo), prostanoid, and NO production, and the effects on blood perfusion experiments. Clopidogrel inhibited platelet aggregation induced in whole blood by collagen and TxB2 production to a greater extent than did ticlopidine. Prostacyclin synthesis did not change after incubation with thienopyridines, whereas aspirin inhibited synthesis in a dose-dependent manner. Thienopyridines increased NO production to a greater extent than did aspirin. All three drugs impaired the platelet-subendothelium interaction under flow conditions. With thienopyridines, the presence of endothelium did not modify the percentage of the surface coated by platelets.

Abstract
Clinical studies have shown that the ability of aspirin to prevent cerebrovascular accidents is weaker in patients with diabetes. The aim of this study was to determine whether high concentrations of glucose modified the effect of aspirin, ticlopidine and clopigodrel on platelet function and platelet-subendothelium interactions. This in vitro study tested three different concentrations of glucose. The effects were analyzed by comparing platelet aggregometry in whole blood, nitric oxide and prostacyclin production in cultures of human endothelial cells, and by quantitative analysis of morphological features of the platelet-subendothelium interaction under flow conditions. High concentrations of glucose increased platelet aggregation (13.9 Omega with 5 mM glucose vs. 21.6 Omega with 16.6 mM) and platelet-subendothelium interactions (28.9% with 5 mM glucose vs.35.2% with 16.6 mM), and decreased nitric oxide and prostacyclin production. In the presence of high concentrations of glucose, the antiaggregant effect of aspirin and its influence on nitric oxide production were diminished (IC50 54 microM with 5 mM glucose vs.556 microM with 16.6 mM glucose), and its effect on the platelet-subendothelium interaction was reduced (10.5% platelet occupancy with 5 mM glucose vs.23% with 16.6 mM glucose). The effects of ticlopidine and clopidogrel were not significantly modified.
