molecules, self‐assembled supramolecularstructures of perylenebisimides (PBIs) are commonly limited to columnar or lamellar structures due to their distinct π‐conjugated scaffolds and unique rectangular shape of perylene cores. The discovery of PBIs with supramolecularstructuresbeyond layers and columns may expand the scope of PBI‐based materials. A series of unconventional spherical packing phases in
Multitarget directed ligands (MTDLs) are arising as promising tools to tackle complex diseases. The main goal of this work is to create powerful modulating agents for neurodegenerative disorders. To achieve this aim, we have combined fragments that inhibit key protein kinases involved in the main pathomolecular pathways of Alzheimer's disease (AD) such as tau aggregation, neuroinflammation and decreased
多靶点定向配体(MTDL)正在成为解决复杂疾病的有前景的工具。这项工作的主要目标是创造针对神经退行性疾病的强大调节剂。为了实现这一目标,我们组合了抑制参与阿尔茨海默病 (AD) 主要病理分子途径(例如 tau 聚集、神经炎症和神经发生减少)的关键蛋白激酶的片段,同时寻找 β-分泌酶 (BACE1) 中的第三种作用,负责β-淀粉样蛋白的产生。我们获得了平衡良好的 MTDL,其在三个不同相关靶标中具有体外活性,并且在两种 AD 细胞模型中具有功效。此外,计算研究证实了这些化合物如何充分适应又长又窄的 BACE1 催化位点。最后,我们采用原位点击化学,使用 BACE1 作为蛋白质模板,作为一种多功能合成工具,使我们能够获得更多 MTDL。

the micro-patterning of PeQDs. AzL can be attached to the surface of the PeQDs during their synthesis without additional ligand exchange. Using the AzL-grafted CsPbBr3 PeQDs, high-color-purity 240 × 240 μm2 square-shaped patterns were successfully fabricated using UV light irradiation, which corresponds to a resolution of >50 pixels per inch.

render chemical synthesis highly time- and resource-intensive. As a result, the design and synthesis of more acid-stable and linker functional group-equipped analogs that retain the low picomolar potency of the parent natural product requires more efficient and step-economical synthetic access. Using uniquely enabling direct complex fragment coupling crotyl- and alkallylsilylation reactions, we report a
