DNA-templated synthesis of trimethine cyanine dyes: A versatile fluorogenic Reaction for sensing G-quadruplex formation
Meguellati, Kamel,Koripelly, Girish,Ladame, Sylvain
, p. 2738 - 2742 (2010)
(Figure Presented) A healthy glow: Fluorogenic peptide nucleic acids (PNAs) functionalized with indoline derivatives are used to specifically sense G-quadruplex formation. Upon hybridization of both PNAs to the singlestranded flanking arms of quadruplex DNA (see scheme), the synthesis of a trimethine cyanine dye is templated. Dye formation can be detected by the appearance of a characteristic fluorescence signal.

Paragraph 0475; 0977-0980, (2020/04/17)
The invention relates to a polysubstituted isoindoline compound represented by a general formula (I), and a preparation method, a pharmaceutical composition and an application thereof. Specifically, as a CRL4CRBNE3 ubiquitin ligase regulator with a novel structure, the polysubstituted isoindoline compound provided by the invention has stronger anti-tumor activity and an anti-tumor spectrum, and can be used for preparing medicines for treating diseases related to CRL4CRBNE3 ubiquitin ligase.

Single-molecule localization microscopy (SMLM) allows the reconstruction of super-resolution images but generally requires prior intense laser irradiation and in some cases additives to induce blinking of conventional fluorophores. We previously introduced a spontaneously blinking rhodamine fluorophore based on an intramolecular spirocyclization reaction for live-cell SMLM under physiological conditions. Here, we report a novel principle of spontaneous blinking in living cells, which utilizes reversible ground-state nucleophilic attack of intracellular glutathione (GSH) upon a xanthene fluorophore. Structural optimization afforded two pyronine fluorophores with different colors, both of which exhibit equilibrium (between the fluorescent dissociated form and the nonfluorescent GSH adduct form) and blinking kinetics that enable SMLM of microtubules or mitochondria in living cells. Furthermore, by using spontaneously blinking fluorophores working in the near-infrared (NIR) and green ranges, we succeeded in dual-color live-cell SMLM without the need for optimization of the imaging medium.

Flash chemistry based on flow microreactor systems allowed alkyllithiums bearing electrophilic functional groups to be successfully generated and used for subsequent reactions. The series of reactions with high reactivity was achieved by extremely accurate control over residence time in a controlled and selective manner.

We designed a combinatorial library of trifunctional scaffold-derived compounds, which were derivatized with 30 different in-house-made azides. The compounds were proposed to mimic insulin receptor (IR)-binding epitopes in the insulin molecule and bind to and activate this receptor. This work has enabled us to test our synthetic and biological methodology and to prove its robustness and reliability for the solid-phase synthesis and testing of combinatorial libraries of the trifunctional scaffold-derived compounds. Our effort resulted in the discovery of two compounds, which were able to weakly induce the autophosphorylation of IR and weakly bind to this receptor at a 0.1 mM concentration. Despite these modest biological results, which well document the well-known difficulty in modulating protein-protein interactions, this study represents a unique example of targeting the IR with a set of nonpeptide compounds that were specifically designed and synthesized for this purpose. We believe that this work can open new perspectives for the development of next-generation insulin mimetics based on the scaffold structure.
