  dihydrofolate reductase inhibitors with potent in vitro and in vivo antibacterial activity against methicillin-resistant Staphylococcus aureus (MRSA) strains. In this work, we extended our previous study to the Gram-negative pathogen Acinetobacter baumannii We determined that optimized N2,N4-disubstituted quinazoline-2,4-diamines are strongly antibacterial against multidrug-resistant A. baumannii strains

  我们以前报道了一系列N2，N4-二取代的喹唑啉-2,4-二胺作为二氢叶酸还原酶抑制剂，对耐甲氧西林的金黄色葡萄球菌（MRSA）菌株具有有效的体外和体内抗菌活性。在这项工作中，我们将先前的研究扩展到革兰氏阴性病原鲍曼不动杆菌。我们确定，当6位为9位时，经优化的N2，N4-二取代喹唑啉-2,4-二胺对多药耐药鲍曼不动杆菌菌株具有较强的抗菌作用。被卤化物或烷基取代基取代。此类药物显示出强大的抗菌活性，MIC低至0.5μM，同时被证明具有强力杀菌作用。有趣的是，这些化合物还具有抗生物膜活性的潜力，可消除MIC处或附近的生物膜中90％的细胞。使用连续传代测定，与现有的叶酸合成抑制剂（如甲氧苄氨嘧啶（增加64倍）和磺胺甲恶唑（增加128倍））相比，我们观察到对这些分子产生抗药性的能力有限（MIC增加4倍）。我们还确定了对人细胞的有限毒性，第4和第5号先导剂的50％致死剂量（LD50s）≤23μM。最后

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

  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.
