  Design, synthesis, and structure–activity relationships of potent GPIIb/IIIa antagonists: discovery of FK419

  摘要：

  The discovery of the non-peptide antiplatelet injectable agent FK419 is reported. Based on the P-turn structure of RGD peptide sequences in the a chain of fibrinogen, which binds the glycoprotein IIb/IIIa (GPIIb/IIIa) on the surface of platelets to induce platelet aggregation, the prototype 2 was designed. After further substituent effects were investigated at the a-position of the carboxylic acid in 2, we enhanced platelet aggregation inhibition, and discovered the useful feature of reduced prolongation of bleeding time. Finally, the potent platelet aggregation inhibitor FK419 (3) could be discovered. FK419 shows a safe feature of reduced prolongation of bleeding time, as well as potent inhibition of platelet aggregation. (c) 2005 Elsevier Ltd. All rights reserved.
