Abstract

NEW MATERIAL:The compound of formula I (R is group of formula II, formula III, formula IV, etc.). EXAMPLE:alpha-Tocopherol gamma-linoleic acid ester. USE:Preventive for thrombosis caused by the coagulation of thrombocyte (e.g. myocardial infarction, ischemic fit after cerebral hemorrhage, cerebral infarction, etc.). It can be used also as a preventive for metastasis of cancer. It remarkably suppresses the thrombocyte-coagulation induced by arachidonic acid or collagen. PREPARATION:The compound of formula I can be prepared by condensing gamma- linoleic acid or its reactive derivative (e.g. thiazolidine-thionamide derivative of carboxylic acid) with alpha-tocopherol, 3-oxymethylpyridine, pyridoxamine or methyl 4-aminobenzoate, in the presence of a condensation agent such as dicyclohexylcarbodiimide.

The PPP268 μa was placed in a cuvette, heated at 37° C. for 2 minutes, added with 2 μL of an ethanol solution of the γ-lylunic acid derivative to be tested, and incubated for 3 minutes, followed by adding the aggregation inducing agent Arakito 21m solution or collagen solution. Platelet aggregation was determined using Born's turbidimetry [

As a result of the test, significant anti-platelet aggregation activity was found as shown in Table 1. Furthermore, in the table, 50% inhibition Ii! Maro means that when the aggregation ability of platelets without introducing the γ-lyrunic acid derivative according to the present invention is set as 100%, the aggregating ability of platelets is suppressed to 50% by introducing the γ-lyrunic acid derivative. It means the m degrees of γ-lyrinnic acid derivative solution required.

The above-mentioned compounds of the present invention effectively inhibit platelet aggregation induced by arachidonic acid or collagen, so they can be used to treat diseases caused by platelet aggregation, particularly myocardial infarction, ischemic attack after cerebral hemorrhage, and cerebral infarction, which are associated with platelet aggregation. It can be used as a prophylactic agent for persistent thrombosis. Furthermore, since platelet aggregation is involved in cancer metastasis, the above compounds of the present invention can also be used as agents for preventing cancer metastasis.
