However, synthesizing stable fused five-, six- and seven-membered organoboron complexes possess significant challenges. In this study, we successfully developed novel mono-nuclear (6-8 & 10) and di-nuclear (9) organoboron complexes supported by triaminoguanidine-salicylidene based -symmetric Schiff base ligands one-step condensation reaction with excess phenylboronic acid.

Characterization of the tail current of Channelrhodopsin-2 variants.

Our study focused on specific ChR2 variants, particularly those with the Step function Opsins (SFO) mutation at the D156-C128 gate. These are widely used in optogenetics due to their heightened sensitivity to light and bi-stable prolonged activation. However, in some ChR2 variants, specifically D156 mutants, a tail current occurs when continuous light exposure is stopped.

Targeting Ribosome Biogenesis for Cancer Therapy with Oral Platinum Complexes.

Cancer cells often upregulate ribosome biogenesis to meet increased protein synthesis demands for rapid proliferation; therefore, targeting ribosome biogenesis has emerged as a promising cancer therapeutic strategy. Herein, we introduce two Pt complexes, ataluren monosubstituted platinum(IV) (SPA, formula: c,c,t,-[Pt(NH)Cl(OH)(CHFNO)], where CHFNO = ataluren) and ataluren bisubstituted platinum(IV) complex (DPA, formula: c,c,t,-[Pt(NH)Cl(CHFNO)], where CHFNO = ataluren), which effectively suppress ribosome biogenesis by inhibiting 47s pre-RNA expression. Furthermore, SPA and DPA induce nucleolar stress by dispersing nucleolar protein NPM1, ultimately inhibiting protein generation in tumor cells.

Nonetheless, its practical implementation encounters considerable obstacles, such as impaired structural integrity, sensitivity to moisture, inadequate high-temperature stability, and being unstable under high-voltage conditions. This study investigates the co-substitution of Cu, Mg, and Ti, guided by principles of the periodic law, to enhance the material's stability under varying conditions.

Intramolecular charge transfer assisted multi-resonance thermally activated delayed fluorescence emitters for high-performance solution-processed narrowband OLEDs.

Multi-resonance thermally activated delayed fluorescence (MR-TADF) emitters have been actively employed in high-resolution solution-processed organic light emitting diodes (OLEDs) due to their excellent color purity. Nonetheless, they are always confronted with intrinsic slow spin flip of triplet excitons, impeding the electroluminescence properties, especially in non-sensitized OLEDs. Herein, we constructed intramolecular charge transfer (ICT) assisted MR-TADF emitters by grafting donor-acceptor-type moieties with a - or -substitution as a pendant on an organoboron multi-resonance core.

A free-radical initiator-based carrier-free smart nanobomb for targeted synergistic therapy of hypoxic breast cancer.

Thermodynamic therapy (TDT) is a promising alternative to photodynamic therapy (PDT) by absorbing heat through thermosensitive agents (TSAs) to generate oxygen-irrelevant highly toxic free radicals. Therefore, TDT can be a perfect partner for photothermal therapy (PTT) to achieve efficient synergistic treatment of anoxic tumors using a single laser, greatly simplifying the treatment process and overcoming hypoxia limitations. However, the issues of how to improve the stability and delivery efficiency of TSAs still need to be addressed urgently.

Effect of Gadolinium Doping on the Optical and Magnetic Properties of Red-Emitting Dual-Mode Carbon Dot-Based Probes for Magnetic Resonance Imaging.

Bioimaging probes based on carbon dots (CDs) can become a useful replacement for existing commercial probes, benefiting clinical diagnostics. While the development of dual-mode CD-based probes for magnetic resonance imaging (MRI), which provides the ability for photoluminescence (PL) detection at the same time, is ongoing, several challenges have to be addressed. First, most of the CD-based probes still emit at shorter wavelengths (blue/green spectral range), which is harmful to biological objects or have very low PL intensity in the biological window of tissue transparency (red/near-infrared spectral range).
