  Discovery of Quinazolines as Histamine H₄ Receptor Inverse Agonists Using a Scaffold Hopping Approach

  摘要：

  From a series of small fragments that was designed to probe the histamine H-4 receptor (H4R), we previously described quinoxaline-containing fragments that were grown into high affinity H4R ligands in a process that was guided by pharmacophore modeling. With a scaffold hopping exercise and using the same in silico models, we now report the identification and optimization of a series of quinazoline-containing H4R compounds. This approach led to the discovery of 6-chloi-o-N-(furan-3-yl)methyl)2-(4-methylpiperzin-1-yl)quinazolin-4-amine (VUF10499, 54) and 6-chloro-2-(4-methylpiperazin-1-yl)-N-(thiophen-2-ylmethyl)quinazolin-4-amine (VUF10497, 55) as potent human H4R inverse agonists (pK(i) = 8.12 and 7.57, respectively). Interestingly, both compounds also possess considerable affinity for the human histamine Hi receptor (H1R) and therefore represent a novel class of dual action H1R/H4R ligands, a profile that potentially leads to added therapeutic benefit. Compounds from this novel series of quirlazolines are antagonists at the rat H4R and were found to possess anti-inflammatory properties in vivo in the rat.

  valuable chemicals at atmospheric pressure is an attractive topic. A novel method of preparing quinazoline derivatives by capturing CX2 (O, S) in reusable, room-temperature, reversible ionic liquids (ReILs) with high yields (up to 98%) at 40 °C and atmospheric pressure was developed in this paper. The different reaction conditions were optimized and the products were easily separated from the ReILs which

  在大气压下将CX 2（O，S）高效转化为有价值的化学物质是一个有吸引力的话题。本文提出了一种通过在可重复使用的，室温可逆的离子液体（ReILs）中捕获CX 2（O，S）来制备喹唑啉衍生物的新方法，该方法在40°C和大气压下具有高产率（高达98％）。 。优化了不同的反应条件，可以轻松地将产物与ReILs分离，可以将其重复使用至少六次，而收率却没有显着降低。捕获CX的可信机构2在ReILs（O，S）提出，它提供了一种绿色，高效的协议来捕获CX 2在ReILs（O，S）的合成喹唑啉衍生物。
