Synthesis of apovincamic acid ethyl ester (Compound 1):
11-Amino-apovincamic acid ethyl ester 500
mg was dissolved in 20 ml of pyridine, 278 mg of benzenesulfonyl chloride was added with stirring in an ice bath, and the mixture was stirred for 2 hours and a half under the same conditions. The solvent was distilled off under reduced pressure, the obtained residue was dissolved in methylene chloride, washed with saturated aqueous NaCl, dried over magnesium sulfate, and the solvent was distilled off under reduced pressure. The obtained residue was applied to a 20-fold amount silica gel column and eluted with ethyl acetate to obtain 478 mg (yield 69%) of the title compound. 1 H-NMR (CDCl 3 , δppm): 7.78 (2H, d, J = 6.9Hz), 7.52 (1H,

The platelet pellet thus obtained is suspended in a modified HEPES Tyrode solution to prepare a washed platelet suspension of about 300,000 cells / μl. Measurement of Platelet Aggregation Reaction (Nephelometry) To 270 μl of the washed platelet suspension obtained above, 3 μl of each test compound dissolved in an appropriate solvent was added, and the mixture was allowed to stand at 37 ° C. for 2 hours.

The absorbance is measured with A tracer 601; manufactured by Nikko Bioscience. Determination of effect of test compound As a control, the absorbance at the time of maximum aggregation by collagen in the presence of the solvent used for the test compound is 100, and the absorbance before the addition of collagen is 0. Then from the absorbance at the time of maximum aggregation by collagen when adding the test compound,
The percentage of inhibition was calculated and expressed as the concentration of the test compound giving 50% inhibition, IC 50 . The results are shown in Table 2.

Oral administration of mg / kg was performed, and 1 hour after the administration, blood was collected from the abdominal aorta to prepare platelet-rich plasma (PRP). Collagen (2.5 μg / ml) was added to this PRP as a platelet aggregation inducer.
Alternatively, the maximum aggregation when arachidonic acid (0.1 mM) was added was measured, and the inhibition rate (%) was calculated. The results are shown in Table 4.
