Abstract
In an effort to develop potent cytotoxic inhibitors of cyclooxygenase (COX), a series of cytotoxic 3-alkylaminopropoxy-9,10-anthraquinone derivatives was screened to evaluate their antiplatelet effect on washed rabbit platelets and human platelet-rich plasma (PRP). Thrombin, arachidonic acid (AA), collagen, and platelet-activating factor (PAF) induced platelet aggregations were potently inhibited by compounds 1, 2, and 3 (each at 300 μM). Of the compounds tested in human PRP, compounds 1, 8, and 10 showed significant inhibition of primary and secondary aggregation induced by epinephrine and had a weak inhibitory effect on cyclooxygenase-1 (COX-1). Molecular docking studies revealed that compounds, 1, 8, and 10 were bound in the active sites of COX-1. This indicated that the antiplatelet effect of these three compounds was partially mediated through the suppression of COX-1 activity and reduced thromboxane formation. It is concluded that the cytotoxic compounds 1, 8, and 10 may interfere the conversion of arachidonic acid to prostaglandin (PG)H2 in the active site of COX-1.
