  Donor−Acceptor−Donor Fluorene Derivatives for Two-Photon Fluorescence Lysosomal Imaging

  摘要：

  As part of a strategy to achieve large two-photon absorptivity in fluorene-based probes, a series of donor- acceptor-donor (D-A-D) type derivatives were synthesized and their two-photon absorption (2PA) properties investigated. The synthesis of D-A-D fluorophores was achieved by efficient preparation of key intermediates for the introduction of central electron acceptor groups. To accomplish the synthesis of two of the new derivatives, a high-yield method for a one-step direct dibromomethylation of phenyl sulfide was developed. The linear and nonlinear optical properties, including UV-vis absorption, fluorescence emission, fluorescence anisotropy, and two-photon absorption (2PA), of the new D-A-D compounds were measured and compared to their D-A or D-D counterparts. Fully conjugated acceptor moieties in the center of the D-A-D fluorophore led to the greatest increase in the 2PA cross section, while weakly conjugated central acceptors exhibited only a modest increase in the 2PA cross section relative to D-A diploar analogs. Encapsulation of the new probes in Pluronic F 108N F micelles, and subsequent incubation in HCT 116 cells, resulted in very high lysosomal colocalization (> 0.98 colocalization coefficient) relative to commercial Lysotracker Red, making the micelle-encapsulated dyes particularly attractive as fluorescent probes for two-photon fluorescence microscopy lysosomal imaging.

• Counter-rotatable dual cinchona quinuclidinium salts and their phase transfer catalysis in enantioselective alkylation of glycine imines
  作者：Jiin Oh、Jihyeon Park、Keepyung Nahm

  DOI：10.1039/d1cc02785a

  日期：——

  Dual cinchona quinuclidinium salts with a diphenyl ether linker were synthesized and used as powerful asymmetric phase transfer catalysts in the α-alkylation of imines of glycine and alanine ester with 0.01–0.1 mol% loading (17 examples, 92–99% ee). Skewed conformers of dual quinuclidiniums at TS were proposed to rationalize their high efficiency via DFT calculations.

  本发明涉及金属超分子化合物在制备抗新冠病毒的药物中的应用，具体提供了手性金属超分子化合物在制备提高RNA G‑四链体的稳定性的制剂中的应用。本发明首先发现了通过金属超分子化合物Λ1金属配合物可以高度稳定SARS‑CoV‑2RNA G‑四链体，并有效抑制病毒蛋白的表达，从而根除SARS‑CoV‑2。然而，对相应对映体Δ1的金属配合物没有检测到明显的效果，显示出显著的对映选择性。更重要的是，Λ1金属配合物更倾向于SARS‑CoV‑2G‑四链体，而不是人类基因组中的各种DNA G‑四链体，这表明其具有治疗COVID‑19的潜力。
