Phenothiazinyl Boranes: A New Class of AIE Luminogens with Mega Stokes Shift, Mechanochromism, and Mechanoluminescence

Phenothiazines with a dimesityl boron moiety, a new class of aminoboranes with B?N linkage, were synthesized. These aminoboranes exhibited interesting photophysical behavior including aggregation-induced emission (AIE), mechanochromism (MC), mechanoluminescence (ML), and a mega Stokes shift (up to 312 nm in hexane). The solid-state emission of the aminoboranes could be switched reversibly by grinding?fuming processes. Furthermore, the phenothiazine derivative with a bromo and an arylborane group at 3- and 7-positions exhibited bright mechanoluminescence.

The design and synthesis of related molecules that are more effective, more selective, and less toxic than aspirin are important objectives of biomedical research.Keep reading other articles of 3-Bromo-10H-phenothiazine!SDS of cas: 3939-23-9

Electrooxidative para-selective C?H/N?H cross-coupling with hydrogen evolution to synthesize triarylamine derivatives

Oxidative C?H/N?H cross-coupling is one of the most atom-economical methods for the construction of C?N bonds. However, traditional oxidative C?H/N?H cross-coupling either required the use of strong oxidants or high reaction temperature, which makes it difficult to tolerate redox active functional groups. Herein we describe an external chemical oxidant-free electrooxidative C?H/N?H cross-coupling between electron-rich arenes and diarylamine derivatives. Under undivided electrolytic conditions, a series of triarylamine derivatives are produced from electron-rich arenes and diarylamine derivatives with high functional group tolerance. Both of the coupling partners are redox active in oxidative C?H/N?H cross-coupling, which enables high regioselectivity in C?N bond formation. Exclusive para-selectivity is observed for the coupling with anilines.

Clinical efficacy of photodynamic therapy as an adjunct to scaling and root planing in the treatment of chronic periodontitis among cigarette smokers: A systematic review and meta-analysis

Background: The aim of the study was to evaluate the clinical efficacy of adjunctive photodynamic therapy (PDT) as compared to scaling and root planing (SRP) alone in the treatment of chronic periodontitis among cigarette smokers. Methods: Electronic databases including EMBASE, MEDLINE, Cochrane Oral Health Group Trials Register and Cochrane Central Register of Controlled Trials were searched up to January 2019. Randomized clinical trials (RCTs) with data on comparison between adjunctive PDT compared to SRP in each group were included. Primary outcomes included clinical attachment level (CAL) gain, while secondary outcomes was probing depth (PD) reduction. The weighted mean differences (WMD) of outcomes and 95% confidence intervals (CI) for each variable were calculated using random and fixed effect models. Results: A total of 5 RCTs were included. Two clinical trials were classified as having a low risk of bias and 3 clinical trials as high risk of bias. The overall effect for CAL gain (WMD= ?0.088, 95% CI= ?0.40 to 0.23, p = 0.58) and PD reduction (WMD= -0.35, 95% CI= -0.87 to -0.17, p = 0.18) was not statistically significant between PDT and SRP groups at follow-up, respectively. Conclusion: Within the limitations of this study, it remains debatable whether PDT as an adjunct to SRP is more effective in clinical attachment level gain as compared to SRP alone in cigarette smokers given that the available scientific evidence is weak.

Selective inhibitors of monoamine oxidase. 4. SAR of tricyclic N- methylcarboxamides and congeners binding at the tricyclics’ hydrophilic binding site

Linear [6.6.6] tricyclic moieties whose center ring is made of two atoms of differing size (here primarily thioxanth-9-ones and phenoxathiins) monosubstituted meta to the sulfur by C(O)NHMe include potent and selective inhibitors of monoamine oxidase A. Similarities with effects on SAR of acylamide and of diazapentacyclic substitution on such rings, including positional variables, the requirement for monomethylation (primary and dialkylated amides are inactive and higher monoalkylated amides show little or no potency), and that sulfur is optimally in sulfone form, suggest that binding to the enzyme occurs similarly in each series. No significantly greater rise in blood pressure was found in rats given sufficient 8 to inhibit most brain and liver MAO A and then followed by oral tyramine than was found on administration of tyramine to controls. This is in contrast to a large blood pressure rise in rats pretreated with phenelzine followed by tyramine, and in accord with the belief that an inhibitor selective for MAO A which is reversibly bound to the enzyme and therefore displaced by any ingested tyramine will not lead to the ‘cheese effect’ (hypertension during treatment with MAO inhibitors usually caused by ingestion of foods containing tyramine).

Synthesis and electronic properties of monodisperse oligophenothiazines

Starting from N-hexylphenothiazine, a versatile construction kit of brominated and borylated phenothiazines can be easily prepared by a sequence of bromination, bromo-lithium exchange/borylation, and Suzuki coupling. Subsequent Suzuki arylation of the building blocks gives soluble, monodisperse, and structurally well defined oligophenothiazines in good yields. The molecular weights at the peak maximum (Mp), obtained by GPC (gel permeation chromatography), and the actual molecular weights of the oligomer series, obtained by mass spectrometry, show excellent correlation. A QM/MM conformational analysis for the complete series reveals that the obvious butterfly-shaped phenothiazine structure multiplies and significantly reduces the hydrodynamic volume of the oligomers. The electronic properties (absorption and emission spectroscopy and cyclic voltammetry) give reasonable correlations with the chain length. With regard to the emission maxima, the effective conjugation length is already reached with the hexamer. Oligophenothiazines are highly fluorescent, with high fluorescence quantum yields, and are simultaneously highly electroactive, with low oxidation potentials.

Photodynamic therapy in the treatment of periodontal diseases: A literature review

Aim: Periodontal diseases remain a challenging clinical condition and hence existing literature showed no consensus on the best treatment option for disease control. The aim of this review was to provide a comprehensive overview of exciting clinical evidence on the effect of photodynamic therapy (PDT) in the treatment of periodontal diseases. Materials and Method: A literature review was performed using MEDLINE, PubMed, Wiley, ScienceDirect, and Scopus using the terms PDT, periodontal disease, laser, scaling and root planning, chronic periodontitis, and aggressive periodontitis. Results: Of a total of 149 articles appeared from various sources, 147 articles were screened and 36 were related to the research objective. Adjunctive therapy with PDT may promote additional clinical and microbiological outcomes. Conclusion: Little information is available with regard to PDT photosensitizers, wavelength, number of sessions, and duration. Therefore, large randomized control trials with longer follow-up are needed to assess the potential of PDT in the treatment of periodontal disease.

Photodynamic therapy in the control of endodontic infections

Introduction: Effective decontamination of the root canal system is key to the success of endodontic treatment. Photodynamic Therapy (PDT) may be an important tool in the reduction of root canal pathogens. Objectives: This study aimed to review the literature on the use of this therapy in Endodontics, and which clinical protocol has been used. Methods: A literature search was carried out using the following databases: PubMed and Scielo, and the following key-words: endodontics; photodynamic therapy; photodynamic therapy endodontics; light-activated disinfection root canal; light activated disinfection endodontics; photo-activated disinfection endodontics; photo-activated disinfection. Results: We selected 18 articles which fit the inclusion criteria: original and relevant articles, clinical and laboratory research, in permanent human teeth, as well as articles reporting the use of photodynamic therapy as a single or adjunct treatment to root canal disinfection, in addition to its efficacy in bacterial reduction. Conclusions: PDT has been shown to be an effective method in microbial reduction of root canals; however, it should be used as an additional method to conventional treatment.
