  intravenously administered antiplatelet fibrinogen receptor (GPIIb/IIIa) antagonists have become established in the acute-care clinical setting for the prevention of thrombosis, orally administered drugs for chronic use are still under development. Herein, we present details from our exploration of structure-activity surrounding the prototype fibrinogen receptor antagonist RWJ-50042 (racemate of 1), which

  尽管在急性护理临床环境中已建立了静脉内施用的抗血小板纤维蛋白原受体（GPIIb / IIIa）拮抗剂，以预防血栓形成，但仍在开发用于长期使用的口服药物。在本文中，我们介绍了围绕原型纤维蛋白原受体拮抗剂RWJ-50042（外消旋体1）的结构活性探索的细节，该结构活性源自涉及纤维蛋白原γ链的独特方法（Hoekstra et al.J.Med。 1995，38，1582）。我们的模拟研究最终发现了有效的口服活性GPIIb / IIIa拮抗剂RWJ-53308（2）。为了从RWJ-50042逐渐发展成为适合临床开发的候选药物，我们进行了一系列优化周期，这些周期采用固相平行合成技术进​​行快速，有效制备了将近250种类似物，对它们的血纤维蛋白原受体亲和力和四种不同激活剂诱导的血小板聚集抑制进行了测定。该策略产生了一些有前途的有希望进行进一步研究的类似物，包括3-（3,4-亚甲二氧基苯）-β-氨基酸类

  An efficient synthesis of β-aryl-β-amino acid enantiomers has been developed via the lipase-catalysed enantioselective hydrolysis of the corresponding racemic ethyl esters in an organic solvent. High enantioselectivities (E >100) were observed when the lipase PS-catalysed reactions were performed with H2O (0.5 equiv) in diisopropyl ether at 45 °C. The products could be easily separated and were obtained

  The present invention relates to novel imidazolidine derivatives of the formula I, 1 in which B, E, W, Y, R, R 2 , R 3 , R 30 , e and h have the meanings given herein. The compounds of the formula I are valuable pharmaceutically active compounds which are suitable, for example, for treating inflammatory diseases, for example, rheumatoid arthritis, or allergic diseases. The compounds of the formula I are inhibitors of the adhesion and migration of leukocytes and/or antagonists of the adhesion receptor VLA-4, which belongs to the integrin group. They are generally suitable for treating diseases which are caused by, or associated with, an undesirable degree of leukocyte adhesion and/or leukocyte migration or in which cell-cell or cell-matrix interactions, which are based on the interactions of VLA-4 receptors with their ligands, play a role. The invention furthermore relates to processes for preparing the compounds of the formula I, to their use and to pharmaceutical preparations which comprise compounds of the formula I.
