Jun 19, 2014 . However, antiplatelet properties of hyperoside have not been studied. In this study, the antiplatelet activities of hyperoside were measured by thrombin- or collagen-induced platelet aggregation in vitro, adenosine diphosphate-induced platelet aggregation in vivo, and the thrombus formation in vivo.
A series of novel 2-aminopyrimidine and 2-Substituted-4,6-diaminopyrimidine derivatives have been synthesized and their antiplatelet aggregation activities were assessed against ADP and arachidonic acid-induced platelet aggregation in human plasma using light transmission aggregometry. Among the tested derivatives.
Identically, N-acetylcysteine inhibited the increase of reactive oxygen species level induced by thrombin in platelets, and supported a link between cellular redox status and caspase activation in activated platelets. Presumably, the antiplatelet activity of wal hull extract is related to its polyphenolic compounds and their.

Oct 3, 2013 . Plan: To synthesize some novel 2-amino thiophenes with various substitutions at 2-amino position for anti-platelet aggregation activity. Preface: Various substituted and condensed thiophenes are reported to possess a wide variety of biological and pharmacological activities such as antibacterial, antifungal.
Resveratrol 3-O-β-d-glucopyranoside (1) has been isolated from the seeds of Erythrophleum lasianthum (Caesalpinioidae, Leguminosae), a South African plant used in traditional medicine, and has shown antiplatelet aggregation activity. The synthesis of 1, related hydroxystilbenes, and their glucosides has been.
Platelet aggregation beyond purpose of haemostasis is the underlying cause of blood-clotting related diseases. Concoctions of P. longifolia are used by Zulu traditional healers to manage such diseases. This work aimed at investigating the anti-platelet aggregation activity of the extracts of this plant and to identify and.

Apr 1, 2016 . ABSTRACT. The death on cardiovascular disease can be caused by thrombosis. Thrombosis is triggered by irreversible activity of thrombocyte aggregation. However, almost all prescribed drugs exhibiting antiplatelet activity are associated with a large number of side effects. Then, exploration of medicinal.
Feb 9, 2016 . Abstract. A series of novel 6-alkylamino(alkoxyl)-2-propylthio-8-azapurine nucleosides were synthesized by an improved route, and the human antiplatelet aggregation activities of these new compounds were evaluated. A self-organizing molecular field analysis method was used to study the.

May 1, 2004 . Abstract. To develop target thrombolytic agents with fibrinolytic activity, antiplatelet aggregation activity and reduced immunogenicity, two staphylokinase variants containing Arg-Gly-Asp (RGD) motif were constructed. Gene expression was induced in E. coli JF1125 and the variants, designated DGR and.

Based on the existing reports regarding the antiplatelet aggregation activity of hydrazone derivatives, a series of indole hydrazone derivatives were considered as potential antiplatelet agents and synthesized. The structures of the synthesized compounds were confirmed by spectral data and elemental analysis. The new.
aromaticum, respectively, were evaluated in vitro for anti-platelet aggregation activity on thrombin, adenosine diphosphate (ADP), and epinephrine-induced rat platelet aggregation. The triterpenes exhibited a dose dependent inhibitory activity on platelet aggregation induced by the three platelet agonists. The compounds.
Benzodiazepines exert many pharmacologic activities at the periphery. Among these activities, some benzodiazepines inhibit platelet aggregation. Triazolam and alprazolam inhibit platelet-activating factor–induced aggregation, 3 and the inhibition of platelet-activitating factor binding to platelets has been proposed to.
