  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。

  日期：2021.6.18

  A lanthanide silylamide-catalyzed tandem reaction of isatins, diethyl phosphite, and 2,3-diarylcyclopropenones has been developed. A series of pyrano[2,3-b]indol-2-ones were synthesized in high yields. The cooperation of the Lewis acidity of the lanthanide center and the Bronsted basicity of the N(SiMe3)2 anion may be the key factor affecting the catalytic activity of lanthanide amides.
