Aromatic Ring Bromination in 1,4-Benzothiazines, 1,4-Benzoxathianes and 1,4-Benzodithianes: the Occurrence of Vicarious Nucleophilic Substitution of Hydrogen and Electrophilic Aromatic Substitution Mechanisms

1,4-benzodithianes, 1,4-benzothiazines and 1,4-benzoxathianes, when treated with bromine in anhydrous chloroform, undergo regiospecific monobromination at the aromatic ring.Based on semiempirical quantum mechanical calculations, the regiochemistry of the reaction in the case of 1,4-benzothiazines and 1,4-benzoxathianes was shown to be consistent with a charge-controlled electrophilic aromatic substitution reaction where the Br+ species comes from monobromosulfonium ions (as 2).On the contrary, in the case of 1,4-benzodithianes, the bromination is accomplished by Br- via an orbital-controlled vicarious nucleophilic substitution of hydrogen occurring on dibromodisulfonium ions (as 4).

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.

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.

Sodium Triethylborohydride-Catalyzed Controlled Reduction of Unactivated Amides to Secondary or Tertiary Amines

The first transition-metal-free catalytic protocol for controlled reduction of amide functions using cheap and bench-stable hydrosilanes as reducing agents has been established. By altering the hydrosilane and solvent, the new method enables the selective cleavage of unactivated C-O bonds in amides and allows the C-N bonds to selectively break via the deacylated cleavage. Overall, this novel process may offer a versatile alternative to current methodologies employing stoichiometric metal systems for the controlled reduction of carboxamides.

Learning from clinical phenotypes: Low-dose biophotonics therapies in oral diseases

This narrative review on the use of biophotonics therapies for management of oral diseases is written as a tribute to Prof. Crispian Scully. His seminal contributions to the field are highlighted by the detailed, comprehensive description of clinical presentations of oral diseases. This has enabled a more thorough, fundamental understanding of many of these pathologies by research from his group as well as inspired mechanistic investigations in many groups globally. In the same vein, a major emphasis of this narrative review is to focus on the evidence from human case reports rather than in vitro or in vivo animal studies that showcases the growing and broad impact of biophotonics therapies. The similarities and differences between two distinct forms of low-dose biophotonics treatments namely photodynamic therapy and photobiomodulation therapy are discussed. As evident in this review, a majority of these reports provide promising evidence for their clinical efficacy. However, a lack of adequate technical details, precise biological rationale, and limited outcome measures limits the current utility of these treatments. Future investigations should attempt to address these shortcomings and develop better designed, rigorous, controlled studies to fully harness the tremendous potential of low-dose biophotonics therapies.
