  第一种高选择性GLUT1抑制剂BAY-876的鉴定和优化。

  摘要：

  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。

  Synthesis and in Vitro Pharmacology of Substituted Quinoline-2,4-dicarboxylic Acids as Inhibitors of Vesicular Glutamate Transport

  摘要：

  The vesicular glutamate transport (VGLUT) system selectively mediates the uptake of L-glutamate into synaptic vesicles. Uptake is linked to an H+-ATPase that provides coupling among ATP hydrolysis, an electrochemical proton gradient, and glutamate transport. Substituted quinoline-2,4-dicarboxylic acids (QDCs), prepared by condensation of dimethyl keto-glutaconate (DKG) with substituted anilines and subsequent hydrolysis, were investigated as potential VGLUT inhibitors in synaptic vesicles. A brief panel of substituted QDCs was previously reported (Carrigan et al. Bioorg. Med. Chem. Lett. 1999, 9, 2607-2612), and showed that certain substituents led to more potent competitive inhibitors of VGLUT. Using these compounds as leads, an expanded series of QDC analogues were prepared either by condensation of DKG with novel anilines or via aryl-coupling (Suzuki or Heck) to dimethyl 6-bromoquino-linedicarboxylate. From the panel of almost 50 substituted QDCs tested as inhibitors of the VGLUT system, the 6-PhCH=CH-QDC (K-i = 167 muM), 6-PhCH2CH2-QDC (K-i = 143 muM), 6-(4'-phenylstyryl)-QDC (K-i = 64 AM), and 6-biphenyl-4-yl-QDC (K-i = 41 muM) were found to be the most potent blockers. A preliminary assessment of the key elements needed for binding to the VGLUT protein based on the structure-activity relationships for the panel of substituted QDCs is discussed herein. The substituted QDCs represent the first synthetically derived VGLUT inhibitors and are promising templates for the development of selective transporter inhibitors.

  therapeutics. Rpn11 is a Zn2+-dependent metalloisopeptidase that hydrolyzes ubiquitin from tagged proteins that are trafficked to the proteasome for degradation. A fragment-based drug discovery (FBDD) approach was utilized to identify fragments with activity against Rpn11. Screening of a library of metal-binding pharmacophores (MBPs) revealed that 8-thioquinoline (8TQ, IC50 value ∼2.5 μM) displayed

  蛋白酶体在组成性或诱导性不稳定的正常蛋白质的降解中起着至关重要的作用，并以此能力发挥调节作用。此外，它还能降解异常/受损/突变/错误折叠的蛋白质，从而发挥质量控制功能。蛋白酶体抑制剂已在多发性骨髓瘤的治疗中得到验证，多种疗法已获得 FDA 批准。 Rpn11 是一种 Zn 2+依赖性金属异肽酶，可水解标记蛋白中的泛素，这些蛋白被运输到蛋白酶体进行降解。采用基于片段的药物发现 (FBDD) 方法来识别具有 Rpn11 活性的片段。对金属结合药效团（MBP）文库的筛选表明，8-硫代喹啉（ 8TQ ，IC 50值~2.5 μM）对Rpn11表现出强烈的抑制作用。 8TQ的进一步合成产生了一种小分子化合物（ 35 ，IC 50值~400 nM），它是 Rpn11 的有效且选择性抑制剂，可阻止培养物中肿瘤细胞的增殖。
