Spectroscopic investigations of vinyl-substituted 10H-phenothiazine

Different 10H-phenothiazine derivatives modified at their 3- and 3,7-positions with conjugated electron-deficient pyridine or pyridinium groups using ethenyl linkers are described. Spectral variations of 3-((E)-2-(Methylpyridium-4-yl)vinyl)-10H-phenothiazine iodide and 3,7-bis((E)-2-(Methylpyridium-4-yl)vinyl)-10H-phenothiazine diiodide, which are attributed to intramolecular charge transfer, electronic rearrangement and contact ion-pair mechanisms, were observed to be either base or ion dependent. Depending on the extent of deprotonation of the nitrogen atom in the 10-position of the phenothiazine core, donor-acceptor or push-pull systems provide fluorophore-switching and potential near infrared sensor application.

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.

2-Azaadamantane N-oxyl (AZADO)/Cu Catalysis Enables Chemoselective Aerobic Oxidation of Alcohols Containing Electron-Rich Divalent Sulfur Functionalities

The chemoselective oxidation of alcohols containing electron-rich sulfur functionalities (e.g., 1,3-dithianes and sulfides) into their corresponding carbonyl compounds with the sulfur groups can sometimes be a demanding task in modern organic chemistry. A reliable method for this transformation, which features azaadamantane-type nitroxyl radical/copper catalysis using ambient air as the terminal oxidant is reported. The superiority of the developed method was demonstrated by comparing it with various conventional alcohol oxidation methods.

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.

Fragment-Based Covalent Ligand Screening Enables Rapid Discovery of Inhibitors for the RBR E3 Ubiquitin Ligase HOIP

Modification of proteins with polyubiquitin chains is a key regulatory mechanism to control cellular behavior and alterations in the ubiquitin system are linked to many diseases. Linear (M1-linked) polyubiquitin chains play pivotal roles in several cellular signaling pathways mediating immune and inflammatory responses and apoptotic cell death. These chains are formed by the linear ubiquitin chain assembly complex (LUBAC), a multiprotein E3 ligase that consists of 3 subunits, HOIP, HOIL-1L, and SHARPIN. Herein, we describe the discovery of inhibitors targeting the active site cysteine of the catalytic subunit HOIP using fragmentbased covalent ligand screening. We report the synthesis of a diverse library of electrophilic fragments and demonstrate an integrated use of protein LC-MS, biochemical ubiquitination assays, chemical synthesis, and protein crystallography to enable the first structure-based development of covalent inhibitors for an RBR E3 ligase. Furthermore, using cell-based assays and chemoproteomics, we demonstrate that these compounds effectively penetrate mammalian cells to label and inhibit HOIP and NF-kappaB activation, making them suitable hits for the development of selective probes to study LUBAC biology. Our results illustrate the power of fragment-based covalent ligand screening to discover lead compounds for challenging targets, which holds promise to be a general approach for the development of cell-permeable inhibitors of thioester-forming E3 ubiquitin ligases.

Bactericidal efficacy of photodynamic therapy against Enterococcus faecalis in infected root canals: A systematic literature review

Objective: The aim was to review the bactericidal efficacy of photodynamic therapy (PDT) against Enterococcus faecalis (E. faecalis) in infected root canals. Methods: To address the focused question “Does PDT exhibit bactericidal effects against E. faecalis in infected root canals?” PubMed/Medline and Google-Scholar databases were searched from 1985 up to August 2013 using various combinations of the following key words: “antibacterial; “bactericidal; “endodontic; “root canal” and “photodynamic therapy”. Original studies, experimental studies and articles published only in English language were included. Letters to the editor, historic reviews and unpublished data were excluded. The pattern of the present review was customized to primarily summarize the pertinent information. Results: Seventeen studies (16 ex vivo and one in vivo) were included. In these studies, numbers of teeth used ranged between 30 and 220 teeth. In these studies, wavelengths of diode laser used, diameter of fiber and power output ranged between 625 and 805. nm, 200. mum and 0.4. cm, and 40. mW and 5. W respectively. Twelve studies reported PDT to be effective in eliminating E. faecalis from infected root canals. Four studies reported conventional irrigation and instrumentation to be more efficient in killing E. faecalis than PDT. One study reported PDT and conventional endodontic regimes to be equally effective in eliminating E. faecalis from infected root canals. In most studies, toluidine blue and/or methylene blue were used as photosensitizers. Conclusion: Efficacy of PDT in eliminating E. faecalis from infected root canals remains questionable.
