  摘要：

  三环凝血酶抑制剂的苯基氨定针中的氢原子与酶选择性口袋 S1 底部的 Asp189 发生相互作用，系统地将这些氢原子替换为氟原子，试图通过降低 pKa 值来改善药代动力学特性。F-替代后，pKa 值以及对凝血酶和胰蛋白酶的抑制常数 Ki 均有所降低。有趣的是，线性自由能关系（LFERs）显示，与胰蛋白酶相比，pKa 值的降低对凝血酶的结合亲和力影响更大。在苯基氨定针的 F-替代对抑制剂三环骨架中的三级胺中心 pKa 值的影响上观察到了意外现象，随后通过 X 射线晶体学分析和从头计算进行了合理化。通过对小分子 X 射线晶体结构的分析和剑桥结构数据库（CSD）的研究，获得了强方向性分子间 C–F⋯CN 交互作用的证据。

  摘要：

  凝血酶是凝血中的关键酶，一直是抗血栓治疗的目标。口服活性凝血酶抑制剂可为静脉和动脉血栓形成提供有效和安全的预防。我们对高效的基于苯甲am的凝血酶抑制剂LB30812（3，K（i）= 3 pM）进行了优化，以提高口服生物利用度。在P1位置研究的各种芳基idine胺中，2,5-噻吩基idine胺有效替代了苯amam，而不会损害凝血酶的抑制作用和口服吸收。通常，在N末端位置进行磺酰胺和磺酰胺衍生化可提供高效的凝血酶抑制剂，但具有适度的口服吸收，而可吸收性强的N-氨基甲酸酯衍生物在S9馏分中的代谢稳定性有限。目前的工作最终是发现含有N-羧甲基和2,5-噻吩啶的化合物22，该化合物表现出最有利的抗凝血和抗血栓形成活性以及口服生物活性（K（i）= 15 pM; F =在大鼠，狗和猴子中分别为43％，42％和15％）。在大鼠和兔子的静脉血栓形成模型中，以重量计，该化合物显示出比低分子量肝素依诺肝素更有效

  these transporters should not be addressed by such an inhibitor. A high-throughput screen against a library of ∼3 million compounds was performed to find a small molecule with this challenging potency and selectivity profile. The N-(1H-pyrazol-4-yl)quinoline-4-carboxamides were identified as an excellent starting point for further compound optimization. After extensive structure-activity relationship explorations

  尽管众所周知的事实是，即使在正常的氧气供应条件下，促进性葡萄糖转运蛋白GLUT1仍是保证许多肿瘤实体葡萄糖消耗增加的关键因素之一（被称为Warburg效应），但仅进行了很少的努力寻找一种GLUT1选择性小分子抑制剂。由于GLUT1家族的其他转运蛋白都参与关键过程，因此此类抑制剂不应解决这些转运蛋白。针对约300万种化合物的库进行了高通量筛选，以发现具有这种具有挑战性的效能和选择性的小分子。N-（1H-吡唑-4-基）喹啉-4-羧酰胺被确定为进一步优化化合物的理想起点。经过广泛的构效关系探索后，获得了对GLUT2，GLUT3和GLUT4的选择性因子> 100的个位数纳摩尔抑制剂。最有前途的化合物BAY-876 [N4- [1-（4-氰基苄基）-5-甲基-3-（三氟甲基）-1H-吡唑-4-基] -7-氟喹啉-2,4-二甲酰胺]在体外具有良好的代谢稳定性，在体内具有较高的口服生物利用度。
