Mass Spectral Fragmentation Patterns of Heterocycles. VII. Reinvestigation of Fundamental Processes in Phenothiazines

Electron impact induced fragmentation patterns of simple phenothiazines have been reinvestigated using metastable ion studies, exact mass measuremants and deuterated derivatives.Secondary fragmentation processes involving ions m/e 198, 171, 167, 166, 154, 140 and 139 have been clarified.Mechanisms for the release of sulfur (SH. and CSH.) nitrogen (HCN and H2CN.) containing fragments from phenothiazine molecular ion are proposed based on the deuterium content of the daughter ions obtained from 1,9-dideuteriophenothiazine.A revised mechanism for the expulsion of ketene from 10-acetylphenothiazine is suggested based on the fragmentation pattern of the 1,9-dideuterioderivative.The composition of m/e 140 was determined by high resolution measurement to be C10H6N and not C11H7 as previously reported.

Studies on Diamagnetic Susceptibility of Biologically Active Heterocycles. 1. Diamagnetic Susceptibility of Phenothiazines

Diamagnetic susceptibilities for a number of phenothiazines are reported.A theoretical method to estimate the diamagnetic susceptibility of these biologically active heterocycles is presented.Phenothiazines have been considered to be composed of two units: one consisting of a benzene nucleus containing amino and thio groups at ortho positions to the substituents and the other consisting of a benzene ring with substituents.The diamagnetic contributions of these two units have been obtained from the diamagnetic susceptibilities of substituted o-aminobenzenethiols and benzenes and have been used in estimating the diamagnetic susceptibilities of phenothiazines.It has provided excellent theoretical results.Such an excellent agreement between measured and estimated values is due to the fact that the interactions between substituents which affect the diamagnetism have been duly accounted for in such calculations.

We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 1910-85-6, and how the biochemistry of the body works.Reference of 1910-85-6

Antimicrobial efficacy of photodynamic therapy on dental implant surfaces: A systematic review of in vitro studies

Background: To systematically review the literature regarding the antimicrobial effects of photodynamic therapy (PDT) on multi-bacterial species and the possible surface alterations of dental implants as a result of PDT. Methods: The addressed focused question was: ?Does PDT show antimicrobial efficacy against multi-bacterial species colonization and result in surface alteration on dental implants?? Electronic databases including MEDLINE and EMBASE up to and including December 2018 were searched. Results: Seven studies were included. Two studies used a total of 110 titanium dental implants, while 1 study included a total of 72 zirconia dental implants. Three studies investigated the antimicrobial PDT effects on titanium discs, while 1 study used titanium plates with germanium prisms. All in-vitro studies used diode laser. Energy fluence was reported only in 2 studies. Power output and density were 100 mW (mW) and 150 mW cm?2, respectively. All in-vitro studies reported the multibacterial species outcomes after the application of antimicrobial PDT. All studies showed a significant reduction in the bacterial load. Only two studies reported the outcomes of microstructural changes on the titanium surface, in which both studies did not report any significant alterations on the titanium implants or discs with the application of PDT. Conclusion: This systematic review demonstrated significant reduction in the bacterial load but inconclusive findings regarding structural alterations on the titanium surface with the use of PDT. The results of this review should be considered preliminary and further in-vitro studies with standardized laser parameters are needed to obtain strong conclusions.

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.

Antimicrobial efficacy of photodynamic therapy and light-activated disinfection against bacterial species on titanium dental implants

Purpose: The aim of this study was to evaluate the efficacy of photodynamic therapy (PDT) and light-activated disinfection (LAD) against a 3-day-old bacterial suspension prepared from three different bacterial species present on titanium dental implants, and to analyze the possible alterations of the implant surfaces as a result of the PDT and LAD. Materials and Methods: The study was conducted on 72 titanium dental implants contaminated with a bacterial suspension prepared from three bacterial species: Prevotella intermedia, Aggregatibacter actinomycetemcomitans, and Porphyromonas gingivalis. The contaminated implants were incubated under anaerobic conditions for 72 hours and then were randomly divided into four experimental groups and two control groups (n = 12 each), according to the following treatment protocols: group 1 (PDT1): PDT (660 nm, 100 mW, 60 seconds) with toluidine blue; group 2 (PDT2): PDT (660 nm, 100 mW, 60 seconds) with phenothiazine chloride dye; group 3 (LAD): light-emitting diode (LED) with toluidine blue; group 4 (toluidine blue): treatment with only toluidine blue for 60 seconds. In the positive control group, the implants were treated with a 0.2% chlorhexidine-based solution for 60 seconds, and in the negative control group, no treatment was used. Results: The highest bacterial reduction was recorded in the PDT1 (98.3%) and PDT2 (97.8%) groups. The results of this study showed that there was a statistically significant reduction of bacteria in the PDT1 and PDT2 groups compared with the negative control group (P < .05), individually for each bacterial species as well as for all three species together. LAD was less effective than PDT1 and PDT2, and did not show a statistically significant difference compared with the negative control or any other treatment group. Toluidine blue was the least effective treatment in terms of both the total bacterial count and the individual count for each bacterial species. Conclusion: Both PDT1 and PDT2 protocols showed a high efficacy against a 3-day-old bacterial biofilm on dental implants and were more effective compared with LAD. Do you like my blog?

Effect of the linkage location in double branched organic dyes on the photovoltaic performance of DSSCs

Two novel double branched D-pi-A organic dyes (DB dyes) are synthesized to investigate the influence of the linkage location in DB dyes on the performance of dye-sensitized solar cells (DSSCs), where phenothiazine is introduced as a donor, thiophene-benzotriazole unit as the pi-bridge and cyanoacrylic acid as the electron-acceptor. The photophysical, electrochemical and photovoltaic properties of the dyes are systematically investigated. The results show that the location of the linkage unit has a small effect on the physical and electrochemical properties of the dyes. However, when the dyes are applied in DSSCs, an obvious decline of short-circuit current (Jsc) and open-circuit voltage (Voc) is found by moving the linkage unit from the donor part to the pi-bridge part. The DSSC based on the dye DB-D with the linkage unit in the donor obtains an overall power conversion efficiency of 6.13%, which is about 68% higher than that (3.65%) of the DSSC based on the dye DB-B with the linkage unit in the pi-bridge. The DB-B based device exhibits a lower efficiency due to its serious aggregation and short electron lifetime. The results indicate that the linkage location of the dyes has a big effect on the performance of the DSSCs.
