Synthesis and Biological Investigation of Phenothiazine-Based Benzhydroxamic Acids as Selective Histone Deacetylase 6 Inhibitors

The phenothiazine system was identified as a favorable cap group for potent and selective histone deacetylase 6 (HDAC6) inhibitors. Here, we report the preparation and systematic variation of phenothiazines and their analogues containing a benzhydroxamic acid moiety as the zinc-binding group. We evaluated their ability to selectively inhibit HDAC6 by a recombinant HDAC enzyme assay, by determining the protein acetylation levels in cells by western blotting (tubulin vs histone acetylation), and by assessing their effects on various cancer cell lines. Structure-activity relationship studies revealed that incorporation of a nitrogen atom into the phenothiazine framework results in increased potency and selectivity for HDAC6 (more than 500-fold selectivity relative to the inhibition of HDAC1, HDAC4, and HDAC8), as rationalized by molecular modeling and docking studies. The binding mode was confirmed by co-crystallization of the potent azaphenothiazine inhibitor with catalytic domain 2 from Danio rerio HDAC6.

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.

Identification of a non peptidic RANTES antagonist

A series of phenothiazines demonstrating inhibition of RANTES binding to THP-1 cell membranes has been identified. The lead compound RP23618 (IC50 = 3 muM) was found to inhibit specific binding of 125I-RANTES, but not 125I-MCP-1 to THP-1 cell membranes and furthermore to antagonise RANTES, but not MCP-1-induced chemotaxis of THP-1 cells.

Effect of photodynamic and laser therapy in the treatment of peri-implant mucositis: A systematic review

Background The present study systematically reviewed the literature to investigate the effect of photodynamic therapy (PDT) or laser therapy (LT) in the management of peri-implant mucositis (p-iM). Methods The electronic databases were searched until October 2017. Outcome measures were bleeding on probing (BOP), plaque index (PI), or probing depth (PD). The addressed PICO question was: ?Is PDT and LT effective in the management of p-iM?? Results A total of five studies included in the qualitative analysis, two of which had a low risk of bias. Three studies used PDT while two studies used LT. All studies reported a significant improvement in clinical peri-implant inflammatory parameters in p-iM. For PDT, one study demonstrated a significant reduction for PDT group as compared to manual debridement (MD), while one study indicated comparable outcomes when tested with probiotics at follow-up. One study used PDT alone and indicated significant improvements in peri-implant parameters at follow-up. However, in the studies using LT, one study demonstrated a significant improvement in peri-implant parameters as compared to scaling and root planing alone, while other study indicated comparable outcomes when compared with manual debridement/chlorhexidine group at follow-up. Conclusion This systematic review demonstrated inconclusive findings to show the effect of PDT or LT in the management of p-iM due to methodological heterogeneity such as non-standard control groups, laser parameters and short follow-up period. The results of this review should be considered preliminary and further, more robust, well-designed studies with long-term follow up and standardized comparators with laser parameters are warranted.

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.

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.

Rearrangement of an aniline linked perylene bisimide under acidic conditions and visible to near-infrared emission from the intramolecular charge-transfer state of its fused derivatives

We have prepared a series of aniline-linked and fused perylene bisimides (PBIs) for making near-infrared (NIR) fluorophores. During this research, we found an unexpected rearrangement reaction on the PBI core for the first time. The aniline- and phenothiazine-fused PBIs exhibit excellent absorption ability and visible-to-NIR emission owing to their intramolecular charge transfer character.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 3939-23-9, help many people in the next few years.3939-23-9

Dual optical responses of phenothiazine derivatives: Near-IR chromophore and water-soluble fluorescent organic nanoparticles

We have designed a conventional one-step organic coupling synthetic method to prepare a series of 10H-phenothiazine (PTZ) derivative fluorophores and investigated their optical behavior under alkaline conditions. The unexpected proton detachment at N-10 position (10N-H) of these PTZ derivatives provides switching between the visible fluorophore and near infrared (NIR) chromophore. Both anionic forms of compounds PTZ-NH and PTZ-OH exhibit strong red emission in alkali DMSO solutions, whereas only anionic PTZ-OH exhibits the near infrared absorption wavelength at 1010 nm. Moreover, the unexpected green fluorescence is observed due to the formation of fluorescent organic nanoparticles (FONs) when PTZ-OH is dissolved in alkaline aqueous conditions. These results indicate that these compounds have the potential for use in alkaline sensor applications, especially in aqueous solution.
