Abstract

The present invention relates to a fused heterocyclic compound having the Formula 1, which is useful as a platelet aggregation inhibitor, a method for preparing the same, and a pharmaceutical composition for inhibiting platelet aggregation comprising the same.

Description

technical field [0001] The present invention relates to a fused heterocyclic compound having the following formula 1 or a pharmaceutically acceptable salt thereof, which is useful as a platelet aggregation inhibitor. [0002] [Formula 1] [0003] [0004] wherein P, Q, R, T and X are as defined herein. [0005] The present invention also relates to a process for preparing a fused heterocyclic compound having Formula 1 or a pharmaceutically acceptable salt thereof. [0006] The present invention also relates to a pharmaceutical composition for inhibiting platelet aggregation, comprising the fused heterocyclic compound having formula 1 or a pharmaceutically acceptable salt thereof as an active ingredient. Background technique [0007] Platelets have long been considered essential for hemostasis. Hemostasis is the body's protective process of stopping bleeding from damaged blood vessels. However, abnormal hemostasis in blood vessels may produce blood clots. Platelets ar...
