  Substituted thiophene-anthranilamides as potent inhibitors of human factor Xa

  摘要：

  A series of thiophene-containing non-amidine factor Xa inhibitors is described. Simple methyl-substituted thiophene analogs were relatively weak inhibitors. However, introduction of hydrophilic substituents at C-4 or C-5 of the thiophene afforded inhibitors with low nanomolar potency. Optimization of the thiophene substituent at C-4 afforded subnanomolar inhibitors with improved in vitro anticoagulant activity. Incorporating basic amine substituents on the thiophene increased hydrophilicity and improved anticoagulant activity. The pharmacokinetic profile of one inhibitor was evaluated in dogs, and the X-ray crystal structure of this compound bound to factor Xa provides insight into the observed SAR for binding to factor Xa.

  A novel domino reaction for the preparation of non-racemic β-proline derivatives is reported. The addition of a methyl 2-(oxetan-3-yl)acetate titanium enolate to chiral tert-butanesulfinyl ketimines followed by an intramolecular oxetane ring-opening provides the highly-substituted pyrrolidine ring systems with three contiguous stereogenic centers.

  For the purpose of discovering novel type-II inhibitors of vascular endothelial growth factor receptor 2 (VEGFR2) kinase, we designed and synthesized 5,6-fused heterocyclic compounds bearing a anilide group. A co-crystal structure analysis of imidazo[1,2-b]pyridazine derivative 2 with VEGFR2 revealed that the N1-nitrogen of imidazo[1,2-b]pyridazine core interacts with the backbone NH group of Cys919

  为了发现新型的血管内皮生长因子受体2（VEGFR2）激酶II型抑制剂，我们设计并合成了带有苯胺基团的5,6-稠合杂环化合物。咪唑并[1,2- b ]哒嗪衍生物2与VEGFR2的共晶体结构分析表明，咪唑并[1,2 - b ]哒嗪核心的N 1-氮与Cys919​​的骨架NH基相互作用。为了保留这种必要的相互作用，我们设计了一系列咪唑并[1,2- a ]吡啶，[1,2,4]三唑并[1,5- a ]吡啶，噻唑并[5,4- b]。]吡啶和1,3-苯并噻唑衍生物在相应位置保持环氮作为氢键受体（HBA）。这样设计的所有化合物均显示出对VEGFR2激酶的强抑制活性，[1,2,4]三唑并[1,5- a ]吡啶13d显示出良好的理化性质。此外，13d以缓慢的解离动力学抑制了VEGFR2激酶，并且还抑制了血小板衍生的生长因子受体（PDGFR）激酶。口服13d在裸鼠的DU145和A549异种移植模型中显示出强大的抗肿瘤功效。
