13C Nuclear Magnetic Resonance of Some Derivatives of Phenothiazines, Pyridobenzothiazines and Phenoxazines

Natural abundance 13C NMR studies were carried out on a series of phenothiazines, pyridobenzothiazines and phenoxazines.Chemical shift assignments were made on the basis of models, coupling patterns and aromatic substituent affects.For most of the compounds studied, substituents influence only the carbon chemical shifts of the substituted carbocyclic ring, while the chemical shifts of the unsubstituted ring are essentially the same as those of the parent heterocyclic compound.However, the 10-acetyl and 4′-nitro-10-phenyl groups affect the chemical shifts of several of the carbon atoms in the phenothiazine nucleus.An explanation in terms of resonance interactions between these groups and the N-10 lone-pair electrons is presented.

We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 3939-23-9, and how the biochemistry of the body works.Computed Properties of C12H8BrNS

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 Letters to the editor, historic reviews and unpublished data were excluded.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.

An efficient para-alkylation of primary and secondary anilines with a variety of sterically encumbered alkenes using a simple beta-diketiminato scandium catalyst is reported. This protocol features 100% atom economy, excellent chemo- and regioselectivity, broad substrate scope, and good functional group tolerance. Mechanistic studies disclosed that the reaction probably proceeded via a tandem hydroamination/Hofmann-Martius rearrangement.
