Visible-light photoswitching of ligand binding mode suggests G-quadruplex DNA as a target for photopharmacology

We report the selective targeting of telomeric G4 DNA with a dithienylethene ligand and demonstrate the robust visible-light mediated switching of the G4 ligand binding mode and G-tetrad structure in physiologically-relevant conditions. The toxicity of the ligand to cervical cancer cells is modulated by the photoisomeric state of the ligand, indicating for the first time the potential of G4 to serve as a target for photopharmacological strategies.

Controlled Generation of Singlet Oxygen in Living Cells with Tunable Ratios of the Photochromic Switch in Metal–Organic Frameworks

Development of a photosensitizing system that can reversibly control the generation of singlet oxygen (1O2) is of great interest for photodynamic therapy (PDT). Recently several photosensitizer–photochromic-switch dyads were reported as a potential means of the1O2control in PDT. However, the delivery of such a homogeneous molecular dyad as designed (e.g., optimal molar ratio) is extremely challenging in living systems. Herein we show a Zr-MOF nanoplatform, demonstrating energy transfer-based1O2controlled PDT. Our strategy allows for tuning the ratios between photosensitizer and the switch molecule, enabling maximum control of1O2generation. Meanwhile, the MOF provides proximal placement of the functional entities for efficient intermolecular energy transfer. As a result, the MOF nanoparticle formulation showed enhanced PDT efficacy with superior1O2control compared to that of homogeneous molecular analogues.

Synthesis, properties, and electrochemistry of a photochromic compound based on dithienylethene and ProDOT

The synthesis, photochromic features, and electrochemistry of a novel material based on dithienylethene (DTE) and 3,3-didecyl-3,4-dihydro-2H-thieno[3,4-b][1,4]dioxepine (didecyl-ProDOT) units are described. It is noteworthy that 1,2-bis(5-(3,3-didecyl-3,4-dihydro-2H-thieno[3,4-b][1,4]dioxepin-6-yl)-2-methylthiophen-3-yl)cyclopent-1-ene can be effciently switched between open and closed states by light in both solution and in the solid poly(methyl metacrylate) (PMMA) matrix. It is also found that the emission of this novel compound can be switched on and off upon irradiation.
