  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.

  Discovery of Potent Cyclic GMP Phosphodiesterase Inhibitors. 2-Pyridyl- and 2-Imidazolylquinazolines Possessing Cyclic GMP Phosphodiesterase and Thromboxane Synthesis Inhibitory Activities

  摘要：

  Moderate cyclic GMP phosphodiesterase (cGMP-PDE, PDE V) inhibitor 2-phenyl-4-anilino-quinazoline (1) was identified utilizing MultiCASE assisted drug design (MCADD) technology. Modification of compound 1 was conducted at the 2-, 4-, and 6-positions of the quinazoline ring for enhancement of cGMP-PDE inhibitory activity. The 6-substituted 2-(imidazol-1-yl)-quinazolines are 1000 times more potent in in vitro PDE V enzyme assay than the well-known inhibitor zaprinast. The 6-substituted derivatives of 2-(3-pyridyl)quinazoline 84 and 2-(imidazol-1-yl)quinazoline 86 exhibited more than 1000-fold selectivity for PDE V over the other four PDE isozymes. In addition, cGMP-PDE inhibitors 64, 65, and 73 were found to have an additional property of thromboxane synthesis inhibitory activity.

  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
