Three novel zinc(II) phthalocyanines substituted with one or two 3,4,5-tris(3,6,9-trioxadecoxy)benzoxy group(s) have been prepared and spectroscopically characterized. These compounds are highly soluble and remain nonaggregated in N,N-dimethylformamide. Upon excitation, they exhibit a relatively weak fluorescence emission and high efficiency to generate singlet oxygen compared with the unsubsti...

A series of photosensitizers (PS), which are meso-substituted tetra-cationic porphyrins, was synthesized in order to study the role of amphiphilicity and zinc insertion in photodynamic therapy (PDT) efficacy. Several properties of the PS were evaluated and compared within the series including photophysical properties (absorption spectra, fluorescence quantum yield Phif, and singlet oxygen quant...

The generation efficiencies of mutation-induced mice when using engineered zinc-finger nucleases (ZFNs) have been generally 10 to 20% of obtained pups in previous studies. The discovery of high-affinity DNA-binding modules can contribute to the generation of various kinds of novel artificial chromatin-targeting tools, such as zinc-finger acetyltransferases, zinc-finger histone kinases and so on...

We describe a fluorometric method for determining zinc protoporphyrin, in which whole-blood specimens collected in heparin/ethylenediaminetetraacetate are prediluted with water, and zinc protoporphyrin is extracted into ethanol/ water (95/5 by voi). The resulting extract has a low absorbance (0.05) at the excitation wavelength (415 nm) of zinc protoporphyrin, and the extraction efficiency is ab...

Nonlinear optical Zinc mixed bisthiourea Cadmium chloride (BTCC) crystals were synthesized and grown by slow evaporation method. The FTIR analysis reveals that the C-N stretching frequencies of thiourea are shifted towards the higher frequencies for pure and Zinc mixed BTCC and the C = S stretching frequencies are shifted towards the lower frequencies for pure and Zinc mixed BTCC crystals. Thes...
