摘要: A series of xanthone derivatives was synthesized and tested in-vitro for their ability to inhibit aggregation rabbit washed platelets human platelet-rich plasma (PRP) induced by various inducers. 2-Prenyloxyxanthone showed the most potent inhibition platelet arachidonic acid (IC50 = 10.2 μM). Of compounds in PRP, 2-[3 (propylamino)-2-hydroxypropoxy]xanthone (4) hydrochloride salt exhibited adrenaline 4.4 μM), whereas evaluation mouse antithrombotic activity, compound 4 protection mice from thrombotic challenge. Compound 4, 2-[3-(isopropylamino)-2-hydroxypropoxylxanthone 2,5 dihydroxyxanthone suppressed secondary PRP. We conclude that antiplatelet effects these are mainly due an inhibitory effect on thromboxane formation.
