Electrochemical Oxidative C?H Amination of Phenols: Access to Triarylamine Derivatives

Dehydrogenative C?H/N?H cross-coupling serves as one of the most straightforward and atom-economical approaches for C?N bond formation. In this work, an electrochemical reaction protocol has been developed for the oxidative C?H amination of unprotected phenols under undivided electrolytic conditions. Neither metal catalysts nor chemical oxidants are needed to facilitate the dehydrogenation process. A series of triarylamine derivatives could be obtained with good functional-group tolerance. The electrolysis is scalable and can be performed at ambient conditions.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! Read on for other articles about Electric Literature of 185137-29-5!, Related Products of 38642-74-9

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.

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.

New banana shaped A?D?pi?D?A type organic dyes containing two anchoring groups for high performance dye-sensitized solar cells

Two new bent A?D?pi?D?A type organic dyes (MA-1 and MA-2) consisting of carbazole and phenothiazine moieties as electron donors with 2,1,3-benzothiadiazole as a pi-linker with two end-anchoring groups are designed, synthesized and tested in DSSCs. The photophysical and electrochemical properties of the dyes are investigated in detail. Incorporation of phenothiazine unit in MA-2 resulted in high HOMO level (0.62?V vs. NHE), with a red shift in absorption maxima and broadening of the absorption spectrum. Under standard global AM 1.5 solar conditions, the MA-2 sensitized solar cells exhibited a short circuit photocurrent density of 13.1?mA?cm?2, an open-circuit voltage of 0.73?V, a fill factor of 0.72, corresponding to an overall conversion efficiency of 6.87%. Such design and development of molecular dyes are useful for improving the overall efficiency of DSSCs.

Why Have Clinical Trials of Antioxidants to Prevent Neurodegeneration Failed? – A Cellular Investigation of Novel Phenothiazine-Type Antioxidants Reveals Competing Objectives for Pharmaceutical Neuroprotection

Purpose: Only a fraction of the currently established low-molecular weight antioxidants exhibit cytoprotective activity in living cells, which is considered a prerequisite for their potential clinical usefulness in Parkinson?s disease or stroke. Post hoc structure-activity relationship analyses have predicted that increased lipophilicity and enhanced radical stabilization could contribute to such cytoprotective activity. Methods: We have synthesized a series of novel phenothiazine-type antioxidants exhibiting systematic variation in their lipophilicity and radical stabilization. Phenothiazine was chosen as lead structure for its superior activity at baseline. The novel compounds were evaluated for their neuroprotective potency in cell culture, and for their primary molecular targets. Results: Lipophilicity was associated with enhanced cytoprotective activity, but only to a certain threshold (logP ? 7). Benzannulation likewise produced improved cytoprotectants that exhibited very low EC50 values of ~8?nM in cultivated neuronal cells. Inhibition of global protein oxidation was the best molecular predictor of cytoprotective activity, followed by the inhibition of membrane protein autolysis. In contrast, the inhibition of lipid peroxidation in isolated brain lipids and the suppression of intracellular oxidant accumulation were poor predictors of cytoprotective activity, primarily as they misjudged the cellular advantage of high lipophilicity. Conclusions: Lipophilicity, radical stabilization and molecular weight appear to form an uneasy triangle, in which a slightly faulty selection may readily abolish neuroprotective activity.

A 2 – cyano phenothiazine preparation method (by machine translation)

The invention relates to a preparation method of 2-cyanophenothiazine. Dehydration reaction is firstly performed, thereby avoiding the complex technical step of performing dehydration refinement after the 2-cyanophenothiazine crude product is generated, and effectively reducing the product decomposition; meanwhile, the 2-cyanophenothiazine generation reaction is performed after dehydration to obviously reduce the recrystallization frequency in the refinement process, so that the recrystallization is only needed once, thereby greatly reducing the loss of the materials and energy sources, lowering the preparation cost and enhancing the reaction yield; and thus, the yield of the preparation method can reach 90.3% or above. Besides, the purity of the product is very high and can reach 99.5% or above, and the content of the impurity amide is less than 0.1%. In addition, the catalyst used by the method can effectively accelerate the reaction, shorten the reaction time and lower the reaction temperature, thereby enhancing the energy utilization ratio and further lowering the cost of the whole preparation process.

Clinical effects of photodynamic therapy as an adjunct to full-mouth ultrasonic scaling and root planing in treatment of chronic periodontitis

Background and aims: Photodynamic therapy (PDT) is a potential strategy to eliminate infection in the specific tissue. It uses lower-power laser to activate a photosensitizing agent. Studies have shown the benefit of PDT in the periodontal treatment. The aim of this study was to evaluate the periodontal changes after applying PDT as an adjunct to one visit full-mouth SRP (scaling and root planing) with subgingival piezoelectric ultrasonic scaler compared with full-mouth SRP alone. Methods: A split-mouth randomized clinical trial was designed. Twenty patients with moderate to severe chronic periodontitis were treated with subgingival piezoelectric ultrasonic device alone in control group and adjunct treated with PDT in the test group. Probing pocket depth (PD), clinical attachment level (CAL), plaque index (PI), gingival bleeding index (GBI) and gingival inflammation index (GI) were evaluated at baseline, 1 month, 3 and 6 months after treatment. Only sites with PD ? 4 mm at baseline were calculated. Results: All periodontal parameters were significantly improved in both groups at 1 month, 3 and 6 months after treatment. All parameters in test group were better than that control group, with statistically significant differences of GBI and GI (P < 0.05) at 3 and 6 months after treatment but no statistically significant differences of PD, CAL and PI. Conclusions: One visit full-mouth ultrasonic SRP seems to have good enough effort for the periodontal status till 6 months. The adjunct treatment of PDT provided positive effect in term of GBI and GI.

Efficient and regioselective synthesis of phenothiazine via ferric citrate catalyzed C-S/C-N cross-coupling

Efficient C-S and C-N cross-coupling reactions have been developed for regioselective, scalable and environmentally benign synthesis of substituted phenothiazine derivatives. Cross-coupling reactions were demonstrated on various challenging substrates using non-toxic, highly economical, readily available ferric citrate as a catalyst to get desired product with high regioselectivity. Atom economy is the added advantage of this protocol since additional N-protection step before coupling and eventual deprotection of the same to obtain the desired product arenot required. To the best of our knowledge, this is the first report on the use of inexpensive ferric citrate as a catalyst without involving any ligand for the synthesis of regioselectively substituted phenothiazine.

Is antimicrobial photodynamic therapy effective as an adjunct to scaling and root planing in patients with chronic periodontitis? A systematic review

The aim of this systematic review was to investigate whether antimicrobial photodynamic therapy (aPDT) as either a primary mode of treatment or an adjunct to non-surgical treatment was more effective than scaling and root planing (SRP) alone in treating chronic periodontitis in terms of clinical attachment level (CAL) gain and probing depth (PD) reduction. The focused question was developed using the Patient, Intervention, Comparison, and Outcome (PICO) format, and two authors independently searched the Medline, EMBASE, Cochrane Library, Web of Science, Google Scholar, and Scopus databases for relevant studies from January 2008 to December 2016. Twenty studies included in this systematic review were randomized clinical trials (RCTs) or quasi-RCTs of aPDT compared to placebo, no intervention, or non-surgical treatment in an adult population. Basic study characteristics, photosensitizing agents and wavelengths used in aPDT, frequency of aPDT application, effect of aPDT on clinical parameters, antimicrobial effect of aPDT in chronic periodontitis, effect of immunological parameters following aPDT and patient-based outcome measures were collected from the studies. Although there was a wide range of heterogeneity in the included studied, they all indicated that aPDT has the potential to be an effective adjunct in the treatment of chronic periodontitis. Long-term, multicenter studies with larger sample sizes are needed before aPDT can be recommended as an effective treatment modality.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Related Products of 1910-85-6, you can also check out more blogs aboutRelated Products of 1910-85-6

Phenothiazine-based benzoxazole derivates exhibiting mechanochromic luminescence: The effect of a bromine atom

Two phenothiazine-based benzoxazole derivates (PVB and BPVB) were designed and synthesized, and their photophysical properties were studied and compared. The results showed that both compounds emitted strong fluorescence in solution and in the solid state. Their emission wavelengths were also strongly affected by solvent polarity, indicating intramolecular charge transfer (ICT) transitions. Interestingly, the two compounds exhibited different mechanochromism. The ground film of PVB without bromine atoms can self-cure and change into the original film within 15 min at room temperature. The fluorescence of the ground film for BPVB showed no changes for at least 2 weeks. Meanwhile, a higher contrast fluorescence change was observed for the solid film of BPVB with bromine atoms under grinding, although PVB and BPVB exhibited similar spectral red shifts after grinding. Based on the spectral results and single-crystal structures, a mechanochromic mechanism is given.
