  Non-Peptide Fibrinogen Receptor Antagonists. 2. Optimization of a Tyrosine Template as a Mimic for Arg-Gly-Asp

  摘要：

  Inhibitors of platelet-fibrinogen binding offer an opportunity to interrupt the final, common pathway for platelet aggregation. Small molecule inhibitors of the platelet fibrinogen receptor GPIIb/IIIa were prepared and evaluated for their ability to prevent platelet aggregation. Compound 23m (L-700,462/MK-383) inhibited in vitro platelet aggregation with an IC50 of 9 nM and demonstrated a selectivity of > 24 000-fold between platelet and human umbilical vein endothelial cell fibrinogen receptors. Dose-dependent inhibition of ex vivo platelet aggregation induced by ADP was achieved with iv infusions of 0.1-10 mu g/kg/min of 23m in anesthetized dogs, with 10 mu g/kg/min completely inhibiting platelet aggregation during the entire 6 h infusion protocol. Platelet aggregatability returned rapidly after the termination of the 23m infusions. These features suggest that 23m may be useful in the treatment of arterial occlusive disorders.

• Synthesis of RGD Analogs as Potential Vectors for Targeted Drug Delivery
  作者：Ji Jiang、Wei Wang、David C. Sane、Binghe Wang

  日期：2001.12

  RGD analogs bind to integrin receptors with high affinity and therefore have the potential to be used as vectors for the targeted delivery of pharmaceutical agents to designated sites. Critical to this application is the ability to synthesize RGD analogs with different side chain functional groups that allow for the ready tethering of pharmaceutical agents without sacrificing their affinity for the

  RGD类似物以高亲和力与整联蛋白受体结合，因此有潜力用作将药物靶向递送至指定部位的载体。对于该应用而言，至关重要的是具有不同侧链官能团的RGD类似物的合成能力，从而可以方便地束缚药物，而又不会显着牺牲其对靶受体的亲和力。制备了一系列打算用作药物递送载体的RGD类似物，并评估了它们通过结合糖蛋白IIb / IIIa抑制血小板聚集的能力。其中，化合物11对ADP活化的血小板的IC50最低。发现这种RGD类似物可以很好地耐受带有各种官能团如酰胺，胺，酯，受保护的胺和聚乙二醇的侧链修饰。具有聚（乙二醇）侧链修饰的化合物保留了对糖蛋白IIb / IIIa的高亲和力（IC50 150 nM）这一事实表明，在不显着牺牲其对RGD类似物的亲和力的情况下，可以将相当大的药剂与这些RGD类似物束缚。预期的受体。
• Synthesis and biological evaluation of PEG-tirofiban conjugates

  日期：2008.3

  We have conjugated tiro. ban, an antagonist of the GPIIb/IIIa integrin receptor, to PEG, and shown that these polymers effectively inhibit platelet aggregation. This inhibition decreased with the size of the polymer. Our goal was to develop new cryoprotective agents to store frozen platelets. Surprisingly, tirofoban-conjugated PEG did not exhibit any protection. (c) 2008 Elsevier Ltd. All rights reserved.
