Spectroscopic and time-resolved fluorescence emission properties of a cationic and an anionic porphyrin in biomimetic media and Candida albicans cells

Spectroscopic and time-resolved fluorescence emission techniques were used to provide information for the interaction of 5,10,15,20-tetrakis(4-N,N,N- trimethylammoniumphenyl) porphyrin (TMAP4+) and 5,10,15,20- tetrakis(4-sulphonatophenyl) porphyrin (TPPS4-) with different biomimetic media and with Candida albicans cells. In n-heptane/sodium bis(2-ethylhexyl)sulfosuccinate (AOT)/water and benzene/benzyl-n- hexadecyldimethylammonium chloride (BHDC)/water reverse micelles interactions were dependent on the micellar interface and the amount of water dispersed in the microemulsion. It was also observed that the DNA binding of cationic porphyrin TMAP4+ led to two lifetimes. In vitro investigations showed that TMAP4+ is bound to C. albicans. Fluorescence lifetime measurements and fluorescence microscopic images provided additional insight into the effects of porphyrin uptake by cells. The results reveal a double localization of TMAP4+ inside of C. albicans cells. Thus, a redistribution of TMAP4+ was observed in unwashed cells, probably due to a relocalisation of molecules that were weakly bound to the cells or remained in solution. However, this effect was not found with molecules tightly bound in the cells, after one washing step.

Near-Infrared Optogenetic Genome Engineering Based on Photon-Upconversion Hydrogels

Photon upconversion (UC) from near-infrared (NIR) light to visible light has enabled optogenetic manipulations in deep tissues. However, materials for NIR optogenetics have been limited to inorganic UC nanoparticles. Herein, NIR-light-triggered optogenetics using biocompatible, organic TTA-UC hydrogels is reported. To achieve triplet sensitization even in highly viscous hydrogel matrices, a NIR-absorbing complex is covalently linked with energy-pooling acceptor chromophores, which significantly elongates the donor triplet lifetime. The donor and acceptor are solubilized in hydrogels formed from biocompatible Pluronic F127 micelles, and heat treatment endows the excited triplets in the hydrogel with remarkable oxygen tolerance. Combined with photoactivatable Cre recombinase technology, NIR-light stimulation successfully performs genome engineering resulting in the formation of dendritic-spine-like structures of hippocampal neurons.

Nanocrystals: A perspective on translational research and clinical studies

Poorly soluble small molecules typically pose translational hurdles owing to their low solubility, low bioavailability, and formulation challenges. Nanocrystallization is a versatile method for salvaging poorly soluble drugs with the added benefit of a carrier-free delivery system. In this review, we provide a comprehensive analysis of nanocrystals with emphasis on their clinical translation. Additionally, the review sheds light on clinically approved nanocrystal drug products as well as those in development.

Two Reaction Mechanisms via Iminium Ion Intermediates: The Different Reactivities of Diphenylprolinol Silyl Ether and Trifluoromethyl-Substituted Diarylprolinol Silyl Ether

The reactions of alpha,beta-unsaturated aldehydes with cyclopentadiene in the presence of diarylprolinol silyl ethers as catalyst proceed via iminium cations as intermediates, and can be divided into two types; one involving a Michael-type reaction (type A) and one involving a cycloaddition (type B). Diphenylprolinol silyl ethers and trifluoromethyl-substituted diarylprolinol silyl ethers, which are widely used proline-type organocatalysts, have been investigated in this study. As the LUMO of the iminium ion derived from trifluoromethyl-substituted diarylprolinol silyl ether is lower in energy than that derived from diphenylprolinol silyl ether, as supported by ab initio calculations, the trifluoromethyl-substituted catalyst is more reactive in a type B reaction. The iminium ion from an alpha,beta-unsaturated aldehyde is generated more quickly with diphenylprolinol silyl ether than with the trifluoromethyl-substituted diarylprolinol silyl ether. When the generation of the iminium ion is the rate-determining step, the diphenylprolinol silyl ether catalyst is the more reactive. Because acid accelerates the generation of iminium ions and reduces the generation of anionic nucleophiles in the Michael-type reaction (type A), it is necessary to select the appropriate acid for specific reactions. In general, diphenylprolinol silyl ether is a superior catalyst for type A reactions, whereas the trifluoromethyl-substituted diarylprolinol silyl ether catalyst is preferred for type B reactions.

Polymer-Supported BINOL Ligand for the Titanium-Catalyzed Diethylzinc Addition to Aldehydes: A Remarkable Positive Influence of the Support on the Enantioselectivity of the Catalyst

A new polymer-supported BINOL (1,1?-Bi-2-naphthol) was synthesized by coupling of aminomethyl polystyrene resin and (S)-2,2?-dihydroxy-1,1?-binaphthyl-3,3?-dicarboxylic acid. This new ligand was found to be more enantioselective for the asymmetric addition of diethylzinc to aldehydes than its “free” analog [Ti(BINOL)iPrO2]. A range of 57-99% ee’s as well as 78-97% yields was obtained, and the electronic properties of the enantioselectivity were also observed.

High-dispersed catalysts of core?shell structured Au@SiO2 for formaldehyde catalytic oxidation

In this article, we first report a correlation between the Au based catalyst with core?shell structure and HCHO catalytic oxidation behavior by adjusting of number of Au cores and the SiO2 shell thickness. The Au@SiO2 catalysts displayed the best HCHO reaction activities when Au cores size is about 5 nm and the SiO2 shell thickness is about 50 nm. Based on the results of characterizations and HCHO catalytic oxidation performance, it is suggested that both single-core and multi-core structures are beneficial to HCHO combustion and the multi-core particles can significantly improve the catalytic performance comparing with single-core particles. It is deduced that Au cores transport electrons to the surface of SiO2 shell which improves the formation of high oxidation states Au (Au+ and Au3+) due to the strong metal-support interaction in core?shell structure. Meanwhile, Au3+ formed in single-core structure and Au+ formed in multi-core structure are both active sites in the catalytic oxidation of HCHO. Besides, it is supposed that Au+ is more effective compared to Au3+. Insight into the activity dependence on the strong Au-SiO2 interaction is not only meaningful for development of advanced uniform well dispersed Au based catalysts, but also supports the development of Au@SiO2 catalysts for practical applications of VOCs elimination.
