Improved Photodecarboxylation Properties in Zinc Photocages Constructed Using <i>m‐</i> Nitrophenylacetic Acid Variants**
نویسندگان
چکیده
The methoxy- and fluoro-derivatives of meta-nitrophenylacetic acid (mNPA) chromophores undergo photodecarboxylation with comparable quantum yields (Φ) to unsubstituted mNPA, but uncage at red-shifted excitation wavelengths. This observation prompted us investigate DPAdeCageOMe (2-[bis(pyridin-2-ylmethyl)amino]-2-(4-methoxy-3-nitrophenyl)acetic acid) DPAdeCageF (2-[bis(pyridin-2-ylmethyl)amino]-2-(4-fluoro-3-nitrophenyl)acetic as Zn2+ photocages. has a high Φ exhibits other photophysical properties XDPAdeCage ({bis[(2-pyridyl)methyl]amino}(9-oxo-2-xanthenyl) acetic acid), the best preforming photocage reported date. Since synthesis is more straightforward than XDPACage, new will be highly competitive tool for biological applications.

Characterization of engineered channelrhodopsin variants with improved properties and kinetics.
Channelrhodopsin 2 (ChR2), a light-activated nonselective cationic channel from Chlamydomonas reinhardtii, has become a useful tool to excite neurons into which it is transfected. The other ChR from Chlamydomonas, ChR1, has attracted less attention because of its proton-selective permeability. By making chimeras of the transmembrane domains of ChR1 and ChR2, combined with site-directed mutagene...

Two novel metal coordination polymers, [Zn5Cl4(BBTA)3].3 DMF (1), and [ZnCl(BBTA)(0.5)(DMA)] (2) {H2-BBTA = 1H,5H-benzo(1,2-d:4,5-d')bistriazole}, have been synthesized under solvothermal conditions using ZnCl2 and H2-BBTA in DMF (DMF = N,N'-dimethylformamide) or DMA (DMA = N,N'-dimethylacetamide). Moreover, a highly efficient microwave synthetic route has been developed for 1. The structures o...
متن کاملVariants of Mixtures: Information Properties and Applications
In recent years, we have studied information properties of various types of mixtures of probability distributions and introduced a new type, which includes previously known mixtures as special cases. These studies are disseminated in different fields: reliability engineering, econometrics, operations research, probability, the information theory, and data mining. This paper presents a holistic ...

The effectiveness of virtual environments has often been linked to the sense of presence reported by users of those virtual environments. Presence studies look investigate the phenomenon of acting and feeling that we are in the world created by computer displays. We propose to study relations between virtual humans and sense of presence in immersive environments. We particularly consider how su...
