  Structure-Based Drug Design of Potent Pyrazole Derivatives against Rhinovirus Replication

  摘要：

  Rhinoviruses (RVs) have been linked to exacerbations of many pulmonary diseases, thus increasing morbidity and/or mortality in subjects at risk. Unfortunately, the wide variety of RV genotypes constitutes a major hindrance for the development of Rhinovirus replication inhibitors. In the current investigation, we have developed a novel series of pyrazole derivatives that potently inhibit the Rhinovirus replication. Compounds 10e and 10h behave as early stage inhibitors of Rhinovirus infection with a broad-spectrum activity against RV-A and RV-B species (EC50 < 0.1 mu M). We also evaluate the dynamics of the emerging resistance of these promising compounds and their in vitro genotoxicity. Molecular docking experiments shed light on the pharmacophoric elements interacting with residues of the drug-binding pocket.

  Abstract Base-mediated stereospecific tandem reactions using para-quinone methides and carbene-like benzyl chlorides are developed. DBU-mediated 1,6-addition/cyclization/isomerization reactions produce triarylsubstituted alkenes in 43–89% yields and Z/E ratios of 5:1 to 35:1 in favor of the Z-isomers. Single-step 1,6-conjugate additions are realized with the mediation of cesium carbonate, and different

• Conformations of Bridged Diphenyls. V. A Nuclear Magnetic Resonance Comparative Study of the Conformations of Identically Substituted Diphenyl Ethers, Sulfides, Methanes, Ketones, Sulfoxides, and Sulfones

  Using n.m.r. methods developed in earlier papers, the conformations of two series, one doubly ortho-substituted and one triply ortho-substituted, of six identically substituted bridged diphenyls were compared. The ethers, sulfides, and methanes have been shown to adopt the same conformation in which the di-ortho-substituted ring is perpendicular to the central bridge plane while the other ring lies in that plane and an ortho hydrogen takes up the "inside" or "proximal" position. The benzophenones and sulfoxides prefer a conformation in which the dihedral angle between each ring and the central plane is about 40–50° and an ortho hydrogen adopts the "outside" or "distal" position. The sulfones adopt a conformation in which the two rings are more nearly perpendicular to the central plane.

  使用在之前的论文中发展的核磁共振方法，比较了两个系列的构象，一个是双邻位取代的，另一个是三邻位取代的，这两个系列都是六个相同取代的桥联二苯基化合物。已经证明醚类化合物、硫醚和甲烷在构象上是相同的，其中二邻位取代的环垂直于中央桥平面，而另一个环位于该平面上，一个邻位氢原子占据“内部”或“近端”位置。苯甲酮和亚砜更倾向于采取一个构象，其中每个环与中央平面之间的二面角约为40-50°，一个邻位氢原子占据“外部”或“远端”位置。砜类化合物采取了两个环更接近垂直于中央平面的构象。
