  The present disclosure relates to bifunctional compounds, ULM— L—PTM, which find utility as modulators of Rapidly Accelerated Fibrosarcoma (RAF, such as c-RAF, A- RAF and/or B-RAF; the target protein). In particular, the present disclosure is directed to bifunctional compounds, which contain on one end a Von Hippel-Lindau, cereblon, Inhibitors of Apotosis Proteins or mouse double-minute homolog 2 ligand which binds to the respective E3 ubiquitin ligase and on the other end a moiety which binds the target protein RAF, such that the target protein is placed in proximity to the ubiquitin ligase to effect degradation (and inhibition) of target protein. The present disclosure exhibits a broad range of pharmacological activities associated with degradation/inhibition of target protein. Diseases or disorders that result from aggregation or accumulation of the target protein, or the constitutive activation of the target protein, are treated or prevented with compounds and compositions of the present disclosure.

• Photoswitchable rotaxanes using the photolysis of alkoxyacridanes

  日期：——

  9-Aryl-9-alkoxy-acridanes and their counterparts, 9-aryl-acridinium ions, have been incorporated into the axles both of one- and two-station [2]rotaxanes. The ring component of the rotaxanes consists of the tetracationic ring cyclobis(paraquat-4,4′-bisphenylene). The electron-rich acridanes represent suitable recognition sites for the electron-poor ring because charge transfer interaction plays an important role. The 9-aryl groups at the acridane unit bearing substituents such as the alkoxy and the amino groups influence the strength of the recognition site. Photoexcited acridanes bearing a suitable leaving group such as the methoxy substituent in the 9-position undergo heterolysis, resulting in the formation of the acridinium methoxides. The acridanes are regenerated by the nucleophilic attack of the methoxide ion at the acridinium ion formed. The lifetime of the ionic state is strongly dependent on the solvent composition. Because the positively charged acridinium ions repel the positively charged ring component of the interlocked molecules, a movement of the ring is initiated provided the molecular axle contains an evasive recognition site. Two-station rotaxanes presented here possess as the second station an anisol unit. Both the photoreaction and the thermal back-reaction render the thermodynamic driving force of the interaction of the ring with one of the two recognition stations. Accordingly, movement of the ring forward and back, driven by Brownian motion, occurs. The switching cycle can also be triggered by acid–base titration. The photoexcitation of the acridane unit present in one-station rotaxanes leads to a very unfavourable acridinium recognition station. However, because of the absence of a second station, the ring remains at the unfavourable acridinium station having interaction with 9-aryl group.

  9-芳基-9-烷氧基吖啶和9-芳基吖啶鎓离子已分别整合到单站点和双站点[2]轮烷的轴中。轮烷的环状部分由四阳离子环cyclobis（对醌二甲烷-4,4'-联苯）组成。富电子的吖啶可作为贫电子环的合适识别位点，因为电荷转移相互作用起着重要作用。吖啶单元上连接的9-芳基取代基，如烷氧基和氨基，会影响识别位点的强度。具有合适离去基团的受激吖啶，如9-位带有甲氧基取代基的吖啶，会发生异裂，形成吖啶鎓甲氧基。通过甲氧基离子对形成的吖啶鎓离子的亲核攻击，可以再生吖啶。离子态的寿命强烈依赖于溶剂成分。由于带正电的吖啶鎓离子排斥带正电的互锁分子的环状部分，如果分子轴包含一个避开的识别位点，就会启动环的移动。这里展示的双站点轮烷的第二个站点是一个苯甲醚单元。光反应和热返回反应都提供了环与两个识别站点之一相互作用的驱动力。因此，环会因布朗运动而前后移动。开关循环也可以通过酸碱滴定来触发。单站点轮烷中存在的吖啶单元的光激发导致了一个非常不利的吖啶鎓识别站点。然而，由于缺乏第二个站点，环仍停留在与9-芳基团相互作用的不利吖啶鎓站点。

  Just subtract water: Amphiphilic π‐conjugated acyclic oligopyrroles form solvent‐assisted H‐aggregates that give rise to vesicular structures in aqueous solution (see figure). The H‐aggregates are sensitive to the conditions and are transformed into J‐aggregates by the removal of water.

  只需减去水即可：两亲性π-共轭无环寡吡咯形成溶剂辅助的H-聚集体，在水溶液中形成囊状结构（见图）。H-骨料对条件敏感，并且通过除去水将其转化为J-骨料。

• Click chemistry based synthesis of dopamine D4 selective receptor ligands for the selection of potential PET tracers
  作者：Ashutosh Banerjee、Simone Maschauer、Harald Hübner、Peter Gmeiner、Olaf Prante

  日期：2013.11

  Taking advantage of click chemistry, a library of N-arylpiperazinylmethyl triazoles bearing fluoro substituted appendages was synthesized and the target compounds were investigated for dopamine and serotonin receptor binding. With the aim to bias their hydrophilicity and to optimize their D4 receptor affinity and selectivity, a concise series of triazoles containing fluoroalkyl, fluoroalkoxy, fluoroalkoxyphenyl, and deoxyfluoroglucosyl substituents was studied. The D4 receptor affinity and selectivity could be tuned by altering the chemical moiety attached to the triazole unit. Among the test compounds, the fluoroethoxyphenyl derivative 15b showed weak partial agonism at D4 and a K-i value of 14 nM, while its fluoropropoxyphenyl homologue 16a turned out to act as a neutral D4 antagonist (K-i = 5.1 nM). Both, 15b and 16a revealed an excellent balance between D4 receptor affinity and subtype selectivity, providing lead candidates for the development of F-18-labeled radioligands for D4 receptor imaging studies by positron emission tomography (PET).
