, (2008/06/13)
The present inventors have discovered three classes of novel α-methylene-γ-butyrolactones with excellent antiplatelet activity. As a result of intensive studies, it has been found that compounds represented by the formula I-III are potent inhibitors of platelet aggregation. STR1 For the formula I, R1 is a methyl, a phenyl group optionally substituted with one or two group selected from halide, (C1 -C4) alkyl, (C1 -C4) alkoxy, phenyl, nitro, amino. For the formula II, R1 is a methyl, a phenyl group optionally substituted with one or two group selected from halide, (C1 -C4) alkyl, (C1 -C4) alkoxy, phenyl, nitro, amino; R2 represents hydrogen, halide, (C1 -C4) alkyl, phenyl, nitro, amino; R3 represents hydrogen, halide, (C1 -C4) alkyl, phenyl, nitro, amino. For the formula III, R1 is a methyl, a phenyl group optionally substituted with one or two group selected from halide, (C1 -C4) alkyl, (C1 -C4) alkoxy, phenyl, nitro, amino; R4 represents hydrogen, hydroxy, (C1 -C4) alkyl. The present invention also provides a cost-efficient method for the preparation of formula I-III. Formula I-III may be administered orally or parenterly with an inert diluent or with a pharmaceutically acceptable carrier in the treatment or the prevention of cardiovascular disease.

As a continuation of our previous studies on the synthesis and antiplatelet activity of coumarin derivatives of α-methylidene-γ-butyrolactones, certain quinoline, flavone, and xanthone derivatives were synthesized and evaluated for antiplatelet activity against thrombin (Thr)-, arachidonic acid (AA)-, collagen (Col)-, and platelet-activating factor (PAF)-induced aggregation in washed rabbit platelets. These compounds were synthesized from quinolin-8-ol, flavon-7-ol, and xanthon-3-ol, respectively, via alkylation and Reformatsky-type condensation. By the comparison with coumarin α-methylidene-γ-butyrolactone 3a, flavone and xanthone derivatives, 3b and 3c, respectively, are more selective in which only AA- and collagen-induced aggregation are strongly inhibited. Most of the quinoline derivatives (9a-e) exbibited broad-spectrum antiplatelet activities.
