1,2-Didehydrophenothiazines: Preparation of 1-Alkyl and 1-Aryl-substituted Phenothiazines by Lithium-directed Alkylation

A general route to 1-alkyl substituted phenothiazines is described.Reactions of 2-chlorophenothiazine with an excess of methyl-, n-butyl-, s-butyl-, t-butyl- or phenyl-lithiums give the corresponding 1-substituted phenothiazines via 10-lithio-1,2-dehydrophenothiazine.Attempts to trap the presumed 1,10-dilithio intermediate failed.The reaction of 1-chlorophenothiazine with s-butyl-lithium results in preferential metallation of the 9-position. 2-Chlorophenothiazine reacts with nitrogen nucleophiles (lithium dialkylamides) to give 2-substituted products.

A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about Computed Properties of C12H8ClNS

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.

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.Product Details of 1910-85-6, you can also check out more blogs aboutProduct Details of 1910-85-6

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.

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.

The effects of repeated applications of antimicrobial photodynamic therapy in the treatment of residual periodontal pockets: a systematic review

The aim of this study was to assess the effects of repeated applications of antimicrobial photodynamic therapy (aPDT) on the non-surgical periodontal treatment of residual pockets. This work was performed and reported according to the Cochrane and PRISMA recommendations, respectively, and registered at the PROSPERO registry (number CRD42017058403). An extensive search of the biomedical literature was conducted on four databases from January 1960 to August 2018, followed by hand searching. Analysis of the quality of the selected studies was based on the risk of bias. Only two randomised controlled clinical trials (RCTs) met the inclusion criteria although they had unclear risk of bias. One study showed that repeated applications of aPDT in association with conventional non-surgical treatment during periodontal maintenance improved all clinical outcomes after 6?months. The other study, which assessed the effects of repeated applications of aPDT in association with ultrasound debridement on periodontal pathogens, showed no significant reduction of the main pathogens after 3?6?months but reported reductions of probing pocket depth and C-reactive protein after 3 and 6?months, respectively, compared to mechanical therapy alone. Concluding, it was not possible to state that repeated applications of aPDT, in association with non-surgical treatment of residual pockets, have effective clinical effects in the periodontal maintenance therapy. Although one can consider that aPDT is a promising adjuvant therapy, it is still necessary to carry out more RCTs with low risk of bias in order to confirm or refute the benefits of multiple applications for residual periodontal pockets.

Photochromic Radical Complexes That Show Heterolytic Bond Dissociation

Photochromic materials have been widely used in various research fields because of their variety of photoswitching properties based on various molecular frameworks and bond breaking processes, such as homolysis and heterolysis. However, while a number of photochromic molecular frameworks have been reported so far, there are few reports on photochromic molecular frameworks that show both homolysis and heterolysis depending on the substituents with high durability. The biradicals and zwitterions generated by homolysis and heterolysis have different physical and chemical properties and different potential applications. Therefore, the rational photochromic molecular design to control the bond dissociation in the excited state on demand expands the versatility for photoswitch materials beyond the conventional photochromic molecular frameworks. In this study, we synthesized novel photochromic molecules based on the framework of a radical-dissociation-type photochromic molecule: phenoxyl-imidazolyl radical complex (PIC). While the conventional PIC shows the photoinduced homolysis, the substitution of a strong electron-donating moiety to the phenoxyl moiety enables the bond dissociation process to be switched from homolysis to heterolysis. This study gives a strategy for controlling the bond dissociation process of the excited state of photochromic systems, and the strategy enables us to develop further novel radical and zwitterionic photoswitches.
