N-(Pyridin-2-yl) arylsulfonamides are identified as inhibitors of 11β-hydroxysteroiddehydrogenasetype1 (11βHSD1), an enzyme that catalyzes the reduction of the glucocorticoid cortisone to cortisol. Dysregulation of glucocorticoids has been implicated in the pathogenesis of diabetes and the metabolic syndrome. In this Letter, we present the development of an initial lead to an efficient ligand with

This communication demonstrates the utility of peri-substituted 1,8-diphenylnaphthalene as an effective buildingblock for the construction of novel conformationally ordered synthetic oligomers displaying cofacial structural features.
self-organize into single stranded helical structures upon forming intramolecularhydrogenbonds. Pentameric strands 11, 12, and 14, heptameric strands 1 and 20, and undecameric strand 15 have been synthesized using stepwise convergent strategies. Single helical conformations have been characterized in the solid state by single crystalX-ray diffraction analysis for four of these compounds. Helices from
由交替的2,6-二氨基吡啶和2,6-吡啶二羰基单元组成的分子链已被设计成在形成分子内氢键时自组织成单链螺旋结构。五聚体链11、12和14,七聚体链1和20以及非十聚体链15已经使用逐步收敛策略合成。通过对这些化合物中的四种进行单晶X射线衍射分析,已表征了固态的单螺旋构象。来自五聚体链12和14的螺旋延伸一圈,来自七聚体20和非十聚体15种的螺旋分别延伸一圈半和二圈半。分子内氢键负责股线的强烈弯曲。极性和非极性有机溶剂中的1 H NMR位移均表明外围芳族基团之间存在分子内重叠。因此,螺旋构象在溶液中也占主导地位。从高能延伸线性构象异构体开始的链折叠的分子随机动力学模拟显示,快速(在300 K时为600 ps)转变为稳定的螺旋构象。
