Phosphorogenic dipyrrinato-iridium(III) complexes as photosensitizers for photodynamic therapy

We have designed and synthesized a family of Ir(III) metal complexes coordinated with two cyclometalated bis-fluorophenylpyridine ligands and an ancillary dipyrromethene which is functionalized with a mesityl group (Ir(dipy)-1), an α-chloroacetyl ester (I

Physicochemical and computational insight of 19F NMR and emission properties of: Meso -(o -aryl)-BODIPYs

A series of electronic and physicochemical parameters were explored to determine their effect on experimental spectroscopic and photophysical data. Through a systematic obtention of a series of meso-(o-aryl)-BODIPYs, 19F NMR spectra were analyzed and thei

QUINONE-METHIDE PRECURSORS WITH BODIPY CHROMOPHORE, METHOD OF PREPARATION, BIOLOGICAL ACTIVITY AND APPLICATION IN FLUORESCENT LABELLING

The invention relates to BODIPY derivatives of Formula (I) that bear one or more functional groups which in the photochemical reaction upon irradiation with visible light undergo deamination and deliver quinone methides. Furthermore, the invention relates

Targetable and fixable rotor for quantifying mitochondrial viscosity of living cells by fluorescence lifetime imaging

It is meaningful to accurately quantify the changes in local viscosity within the mitochondria of living cells, because viscosity influences mitochondrial network organization and metabolite diffusion. Although many molecular probes targeting mitochondria have been reported, almost all of them are not fixed to the mitochondria. Thus, they may not be suitable for sensing in abnormal mitochondria with lowered potential. In order to monitor viscosity in all mitochondria, no matter their working or health status, we develop the first fixable BODIPY (boron-dipyrromethene) rotor, named Vis-A. Vis-A contains an aldehyde group as an anchor to react with amino groups of proteins, which make it immobilizable in mitochondria. Vis-B, the reference compound without such anchor unit, is also synthesized. Both Vis-A and Vis-Bshow excellent mitochondrial targetability, as good as the commercially available mitochondrial dye (Mito Tracker Deep Red). However, when cells are chemically treated to decrease the mitochondrial potential, only Vis-A continues emitting strong fluorescence in mitochondria, but the signals of Vis-B and Mito Tracker Deep Red completely disappear. This comparison confirms that Vis-A not only specifically localizes in mitochondria, but also can be stably retained there. Then, Vis-A is applied to detect the mitochondrial viscosity of living cells by Fluorescence Lifetime Imaging (FLIM). Especially, with the aid of Vis-A, the changes in viscosity under typical pathological conditions (i.e., treatment with rotenone and carbonylcyanide-m-chlorophenylhydrazone (CCCP)) for mitochondria are monitored by FLIM.

Molecular Rotors for the Detection of Chemical Warfare Agent Simulants

The fluorogenic probe o-OH is able to detect and quantify organophosphorus nerve agent mimics in solution and in the vapor phase following immobilization on a solid substrate, making the system a suitable candidate for the field detection of chemical warfare agents. Detection is achieved by the suppression of internal rotation upon phosphorylation of a reactive phenolate, resulting in a large fluorescence turn-on response.

Structural diversity in heteroleptic dipyrrinato copper(II) complexes

Synthesis and characterization of the heteroleptic dipyrrinato complexes [Cu2(2-pcdpm)2(acac)2] (1), [Cu 2(2-pcdpm)2(hfacac)2] (2), [Cu 3(4-OHdpm)2(acac)4]

DNA binding and anti-cancer activity of redox-active heteroleptic piano-stool Ru(II), Rh(III), and Ir(III) complexes containing 4-(2-methoxypyridyl)phenyldipyrromethene

The synthesis of four novel heteroleptic dipyrrinato complexes [(η6-arene)RuCl(2-pcdpm)] (η6-arene = C 6H6, 1; C10H14, 2) and [(η5-C5Me5)MCl(2-pcdpm)] (M = Rh, 3; Ir, 4) containing a new chelating ligand 4-(2-methoxypyridyl)-phenyldipyrromethene (2-pcdpm) have been described. The complexes 1-4 have been fully characterized by various physicochemical techniques, namely, elemental analyses, spectral (ESI-MS, IR, 1H, 13C NMR, UV/vis) and electrochemical studies (cyclic voltammetry (CV) and differential pulse voltammetry (DPV)). Structures of 3 and 4 have been determined crystallographically. In vitro antiproliferative and cytotoxic activity of these complexes has been evaluated by trypan blue exclusion assay, cell morphology, apoptosis, acridine orange/ethidium bromide (AO/EtBr) fluorescence staining, and DNA fragmentation assay in Dalton lymphoma (DL) cell lines. Interaction of 1-4 with calf thymus DNA (CT DNA) has also been supported by absorption titration and electrochemical studies. Our results suggest that in vitro antitumor activity of 1-4 lies in the order 2 > 1 > 4 > 3.

A novel Bodipy-Dipyrrin fluorescent probe: Synthesis and recognition behaviour towards Fe (II) and Zn (II)

We present the design, synthesis, characterization and spectral studies for a new Zn (II) and Fe (II) selective fluorescent probe, 4,4-Difluoro-8-{3-[(4- phenoxy-dipyrromethene)propoxy]}-4-bora-3a,4a-diazaindacene (DPYBODPY). DPBODPY consists of a terminal fluorophore and a selective ligand and was designed to detect significant changes in absorbance and/or fluorescence on metal ion binding. The fluorophore is based on the Bodipy unit due to its excellent photophysical properties, while the dipyrrin unit has specific recognition abilities for Fe2+ and Zn2+ ions. The combination of these two structures is optimised to achieve significant spectral changes in the presence of Fe2+ and Zn2+ ions.
