Impact of benzannulation on ESIPT in 2-(2 ‘-hydroxyphenyl)-oxazoles: a unified perspective in terms of excited-state aromaticity and intramolecular charge transfer

Hydroxyphenyl-azoles are among the most popular ESIPT (Excited State Intramolecular Proton Transfer) scaffolds and as such, they have been thoroughly studied. Nevertheless, some aspects regarding the interplay between the emissive properties of these fluorophores and the size of their pi-conjugated framework remain controversial. Previous studies have demonstrated that benzannulation of 2 ‘-hydroxyphenyl-oxazole at the phenol group of the molecule can lead to either red- or blue-shifted fluorescence emission, depending on the site where it occurs. In this report, benzannulation at the heterocyclic unit (the oxazole site) is analysed in order to get the whole picture. The extension of pi-conjugation does not significantly affect the ESIPT emission wavelength, but it leads instead to higher energy barriers for proton transfer in the first excited singlet state, as a consequence of dramatic changes in the charge transfer character of excitation caused by successive benzannulation. Theoretical calculations revealed an interesting connection between intramolecular charge transfer and excited-state aromaticity in the S-1 state. The theoretical approach presented herein allows the behaviour of hydroxyphenyl-oxazoles in the excited state to be rationalized and, more generally, a deeper understanding of the factors governing the ESIPT process to be obtained, a crucial point in the design of new and efficient fluorophores.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 1895-39-2 help many people in the next few years. Name: Sodium 2-chloro-2,2-difluoroacetate.

Investigation of thermal and fluorescent properties of benzoxazole-linked triphenylamine-based co-polyimides

A series of novel fluorescent co-polyimides are obtained by combining N (1)-(4-aminophenyl)-N (1)-(4-(benzo[d]oxazol-2-yl) phenyl) benzene-1,4-diamine and 4,4 ‘-oxydianiline with four aromatic anhydride, 3,3 ‘,4,4 ‘-benzophenonetetracarboxylic dianhydride, pyromellitic dianhydride, 4,4 ‘-oxydiphthalic anhydride, and 4,4 ‘-(hexafluoroisopropylidene)diphthalic anhydride following conventional polycondensation method. The resultant co-polyimides are characterized by elemental, Fourier transform infrared spectral analysis and gel permeation chromatography. All newly prepared polyimides (PIs) exhibit shallow highest occupied molecular orbital energy levels in the range of -4.47 to -4.98 eV and have reasonable optical bandgaps. The photoluminescence spectral analysis shows blue to green emission in solution form. Thermal and solubility properties reveal that the PIs with pendant 4-(benzo[d]oxazol-2-yl group linked to triphenylamine unit in polymer backbone impart not only good thermal stability but also appreciable solubility making these new co-polyimides versatile for multipurpose usage.

Micro-structured fluorescent powders for detecting latent fingerprints on different types of surfaces

Benzazole dyes have shown great potential for application in different fields of science due to their intense and stable photoluminescence properties, associated with high sensitivity. In this study, we developed and evaluated micro-structured fluorescent powders based on benzazole dyes for fingerprint detection on different types (porous and non-porous) and colors (dark, white, and multi-colored) of surfaces. The new micro-structured powders were obtained by embedding a small amount of benzazole dye into a silica matrix (1:100 and 1:300 mass ratio) using an aqueous solution or ethanol under ambient conditions. The photophysical properties were characterized by UV-vis absorption and fluorescence emission spectroscopy. To assess the efficiency of these proposed powders, comparisons were performed with commercially available black, white, and fluorescent powders (Sirchie (R)) for different types of surfaces. The developed micro-structured powders showed intense fluorescence emission in the blue-green region, and a sharp contrast with the fingerprint residues when exposed to long wavelengths of UV light (365 nm) was observed, producing distinct ridge details on all examined surfaces.

Pyrazolopyrimide library screening in glioma cells discovers highly potent antiproliferative leads that target the PI3K/mTOR pathway

The search for novel targeted inhibitors active on glioblastoma multiforme is crucial to develop new treatments for this unmet clinical need. Herein, we report the results from a screening campaign against glioma cell lines using a proprietary library of 100 structurally-related pyrazolopyrimidines. Data analysis identified a family of compounds featuring a 2-amino-1,3-benzoxazole moiety (eCF309 to eCF334) for their antiproliferative properties in the nM range. These results were validated in patient-derived glioma cells. Available kinase inhibition profile pointed to blockade of the PI3K/mTOR pathway as being responsible for the potent activity of the hits. Combination studies demonstrated synergistic activity by inhibiting both PI3Ks and mTOR with selective inhibitors. Based on the structure activity relationships identified in this study, five new derivatives were synthesized and tested, which exhibited potent activity against glioma cells but not superior to the dual PI3K/mTOR inhibitor and lead compound of the screening eCF324.

Synthesis of Various 2-Aminobenzoxazoles: The Study of Cyclization and Smiles Rearrangement

This study reports two synthetic approaches leading to 2-aminobenzoxazoles and their N-substituted analogues. Our first synthetic strategy involves a reaction between various o-aminophenols and N-cyano-N-phenyl-p-toluenesulfonamide as a nonhazardous electrophilic cyanating agent in the presence of Lewis acid. The second synthetic approach uses the Smiles rearrangement upon activation of benzoxazole-2-thiol with chloroacetyl chloride. Both developed synthetic protocols are widely applicable, afford the desired aminobenzoxazoles in good to excellent yields, and use nontoxic and inexpensive starting material.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 319-03-9, in my other articles.

Biological evaluation and pharmacophore modeling of some benzoxazoles and their possible metabolites

A series of benzoxazole derivatives and some possible primary metabolites were evaluated as anticancer agents. In vitro anti-proliferative activities of the compounds were tested using the SRB assay on cancerous (HeLa) and non-cancerous (L929) cell lines. It was found that 17 of 21 tested compounds had cytotoxic activity on HeLa cells and the cytotoxic activities of the compounds were 15-700 times higher than on L929 cells. We generated two distinct pharmacophore models for the cytotoxic activities of the compounds on HeLa and L929 cells. While active compounds such as camptothecin and X8 fitted the two models generated for both cell lines, selective cytotoxic compounds such as XT3B fitted only the model generated for HeLa cells. Evaluation of the genotoxic activities of the cytotoxic compounds with the alkaline comet assay revealed that compounds X17 and XT3 showed strong genotoxic effects against HeLa cells at low concentrations whereas they had no genotoxic effect on L929 cells. Due to the selective ability for inducing DNA strand breaks only on cancerous cells, the compounds were identified as effective derivatives for anticancer candidates.

The design, synthesis and evaluation of 2-aminobenzoxazole analogues as potent and orally efficacious ChemR23 inhibitors

We previously reported 2-aminobenzoxazole analogue 1 as a potent ChemR23 inhibitor. The compound showed inhibitory activity against chemerin-induced calcium signaling through ChemR23 internalization in CAL-1 cells, which are cell lines of plasmacytoid dendric cells (pDCs). Furthermore, compound 2 inhibited chemotaxis of CAL-1 triggered by chemerin in vitro. However, we noted a difference in the ChemR23 response to our inhibitor between rodents and non-rodents in a previous study. To address this issue, we performed optimization of ChemR23 inhibitors using CAL-1 cells endogenously expressing human ChemR23 and conducted a pharmacokinetics study in cynomolgus monkeys. Various substituents at the 4-position of the benzoxazole ring exhibited potent in vitro bioactivity, while those at the 6-position were not tolerated. Among substituents, a carboxyl group was identified as key for improving the oral bioavailability in cynomolgus monkeys. Compound 38a with the acidic part changed from a tetrazole group to a 1,2,4-oxadiazol-5-one group to improve bioactivity and pharmacokinetic parameters exhibited inhibitory activity against chemerin-induced chemotaxis in vitro. In addition, we confirmed the ChemR23 internalization of pDCs by compound 38a orally administered to cynomolgus monkeys. These 2-aminobenzoxazole-based ChemR23 inhibitors may be useful as novel immunotherapeutic agents capable of suppressing the migration of pDCs, which are known to be major producers of type I interferons in the lesion area of certain autoimmune diseases, such as systemic lupus erythematosus and psoriasis.
