An Anti-Inflammatory Azaphenothiazine Inhibits Interferon beta Expression and CXCL10 Production in KERTr Cells

An azaphenothiazine derivative, 6-chloroethylureidoethyldiquino[3,2-b; 2 0,3 0 -e][1,4]thiazine (DQT), has recently been shown to exhibit immunosuppressive activities in mouse models. It also inhibited the expression of CXCL10 at the protein level, at non-toxic concentrations, in the culture of KERTr cells treated with double-stranded RNA, poly(I:C). In this report, we demonstrated that DQT inhibits the transcription of the CXCL10 gene. Although CXCL10 is an IFN gamma-inducible protein, we found that the CXCL10 protein was induced without the detectable release of IFN gamma or I kappa B degradation. Hence, we concluded that IFN gamma or NF kappa B was not involved in the regulation of the CXCL10 gene in KERTr cells transfected with poly(I: C), nor in the inhibitory activity of DQT. On the other hand, we found that IFN beta was induced under the same conditions and that its expression was inhibited by DQT. Kinetic analysis showed that an increase in IFN beta concentrations occurred 4-8 h after poly(I: C) treatment, while the concentration of CXCL10 was undetectable at that time and started to increase later, when IFN beta reached high levels. Therefore, DQT may be regarded as a new promising inhibitor of IFN beta expression and IFN beta-dependent downstream genes and proteins, e.g., CXCL10 chemokine, which is implicated in the pathogenesis of autoimmune diseases.

Visible light-driven oxidation of arsenite, sulfite and thiazine dyes: A new strategy for using waste to treat waste

Recently, the advanced oxidation processes (AOPs) based on sulfate radical (SO4 center dot-) using sulfite has received increasing concerns. Metal-free activation of sulfite is still in urgent demands from the perspective of cleaner production since the reported efficient systems containing sulfite has been relied on the transition metals. In this work, methylene blue (MB+), a well-known photosensitizer and thiazine dye contaminant, was utilized to activate sulfite for the efficient photooxidation of arsenite (As(III)) to arsenate (As(V)) under visible light (LED lamps with wavelength 640 nm) and sunlight, respectively. The initial oxidation rates of 5-40 mu M As(III) are 28-folde116-fold as that of the decolorization of 0.27 mu M MB+ with 50 mu M sulfite at pH 7.3. The maximum stoichiometric ratio MB+: As(III): sulfite was obtained to be 1 : 142: 247, suggesting an efficient utilization of both MB+ and sulfite as waste resources. The electrical energy per order (EE/O) index was calculated to be 1.83 x 10(-3) kWh L-1 for the visible light-MB+-sulfite system, which is much less than those reported systems. Oxysulfur radicals (mainly peroxymonosulfate radical, SO5 center dot-) produced in this photochemical system are responsible for As(III) oxidation. The other two common thiazine dyes (thionine and Azure B) are also capable of activating sulfite for As(III) oxidation due to the same chromophores. Thus the novel strategy of using waste sulfite and the thiazine dyes is promising for As(III) oxidation under sunlight, with which low-concentration wastes of thiazine dye and sulfite can be utilized to achieve the goal of cleaner production.

Topically applied azaphenothiazines inhibit experimental psoriasis in mice

The therapeutic efficacy of topically applied azaphenothiazine derivatives: 9-chloro-6-acetylaminobutylquinobenzo[3,2-b] [1,4]thiazine (compound 4) and 6-chloroethylureidoethyldiquino[3,2-b;2′;3′-e] [1,4]thiazine (compound 5) in the amelioration of inflammatory symptoms of imiquimod-induced psoriasis in mice was investigated. Clobederm (R), containing clobetasol propioniate, served as a reference drug. The application of the compounds led to thinning of the epidermis and reduction of the cell layers. The suppressive actions of the compounds were even stronger with regard to pathological changes of the dermis. The compounds also exerted generalized, anti-inflammatory effects by decreasing the number of circulating leukocytes, lowering subiliac lymph node weight and partially normalizing an altered blood cell composition. The changes in the composition of main cell types in the epidermis and dermis were less affected by the compounds. In addition, both compounds inhibited to a similar degree production of tumor necrosis factor alpha (TNF alpha) in human whole blood cell culture. Whereas compound 5 strongly inhibited IL-8 and CXCL10 chemokines in human keratinocytes – KERTr cell line, transfected with poly(I:C), the suppressive action of compound 4 in this model was weak. In addition, compound 5, but not compound 4, exhibited at low doses proapoptotic properties with regard to colonic cell lines. In summary, we demonstrated the therapeutic potential of two selected azaphenotiazines in the amelioration of the skin pathology elicited in a mouse experimental model of psoriasis.

Pathological conformations involving the amino terminus of tau occur early in Alzheimer’s disease and are differentially detected by monoclonal antibodies

Conformational changes involving the amino terminus of the tau protein are among the earliest alterations associated with tau pathology in Alzheimer’s disease and other tauopathies. This region of tau contains a phosphatase-activating domain (PAD) that is aberrantly exposed in pathological forms of the protein, an event that is associated with disruptions in anterograde fast axonal transport We utilized four antibodies that recognize the amino terminus of tau, TNT1, TNT2 (a novel antibody), Tau12, and Tau13, to further study this important region. Using scanning alanine mutations in recombinant tau proteins, we refined the epitopes of each antibody. We examined the antibodies’ relative abilities to specifically label pathological tau in non-denaturing and denaturing assays to gain insight into some of the mechanistic details of PAD exposure. We then determined the pattern of tau pathology labeled by each antibody in human hippocampal sections at various disease stages in order to characterize PAD exposure in the context of disease progression. The characteristics of reactivity for the antibodies fell into two groups. TNT1 and TNT2 recognized epitopes within amino acids 7-12 and specifically identified recombinant tau aggregates and pathological tau from Alzheimer’s disease brains in a conformation-dependent manner. These antibodies labeled early pre-tangle pathology from neurons in early Braak stages and colocalized with thiazine red, a marker of fibrillar pathology, in classic neurofibrillary tangles. However, late tangles were negative for TNT1 and TNT2 indicating a loss of the epitope in later stages of tangle evolution. In contrast, Tau12 and Tau13 both identified discontinuous epitopes in the amino terminus and were unable to differentiate between normal and pathological tau in biochemical and tissue immunohistological assays. Despite the close proximity of these epitopes, the antibodies demonstrated remarkably different abilities to identify pathological changes in tau indicating that detection of conformational alterations involving PAD exposure is not achieved by all N-terminal tau antibodies and that a relatively discrete region of the N-terminus (i.e., amino acids 7-12, the TNT1 and TNT2 epitope) is central to the differences between normal and pathological tau. The appearance of PAD in early tau pathology and its disappearance in late-stage tangles suggest that toxic forms of tau are associated with the earliest forms of tau deposits. Collectively, these findings demonstrate that the TNT antibodies are useful markers for early conformational display of PAD and provide information regarding conformational changes that have potential implications in the toxic mechanisms of tau pathology.

Mortino (Vaccinium floribundum Kunth) berry assisted green synthesis and photocatalytic performance of Silver-Graphene nanocomposite

Mortitio (Vacciniumf/oribundum Kunth) is a wild shrub native to South America, whose berries are widely consumed in Ecuador as fresh fruit, juice and jam. We reported a green synthesis of Silver-Graphene (Ag-G) nanocomposite through the reduction of Ag+ and graphene oxide using berry extract of Morthio. Silver nanoparticles were anchored onto the graphene sheets by ultrasonication and solar light irradiation. The as-prepared 4g-G nanocomposite was characterized by Fourier transform infrared spectroscopy, UV-vis spectroscopy, Scanning transmission electron microscopy, Scanning electron microscopy with energy dispersive X-ray spectrometry, and X-ray diffraction techniques. The photocatalytic activities of the Ag-G nanocomposite were evaluated by the degradation of methylene blue (MB) and methylene orange (MO) in an aqueous medium under sunlight irradiation. The photocatalytic activity of Ag-G nanocomposite for the degradation of MB (k = 0.0163283 min(-1)) > MO (k=0.0140985 min(-1)), due to the anchoring of Ag nanoparticles on the graphene sheets and thiazine ring of MB is more susceptible to photodegradation than the azo bond of MO. This ecofriendly and green reduction method avoids the use of toxic reagents, and it might be useful for biocompatible materials in the future engineering applications. (C) 2016 Elsevier B.V.
