Facile, Odourless, Quantitative Synthesis of 3-Hydroxy-3,4-dihydro-2H-1,4-thiazines

A sulfa-Michael addition/formal [3+3] annulation cascade reaction between 1,4-dithiane-2,5-diol and 1,2-diaza-1,3-dienes by a one-pot base-catalysed strategy was developed. This metal-free and odourless method provides a practical and facile approach to 1,4-thiazines obtained in total atom economy and in quantitative yields. Furthermore, the synthesis could be scaled-up to the gram scale.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 151-21-3, in my other articles. Category: thiazines.

An efficient ligand-free ferric chloride catalyzed synthesis of annulated 1,4-thiazine-3-one derivatives

A straight forward route for the synthesis of coumarin-, quinolone-annulated 1,4-thiazine-3-one derivatives has been achieved by using sodium sulfide as the sulfur source and ferric chloride as catalyst in a ligand-free condition. The synthetic procedure is simple, inexpensive, and affords the products in good yields. This methodology is also applicable to naphthalene and benzene systems. (C) 2014 Elsevier Ltd.

Dual catalysis system for ring-opening polymerization of lactones and 2,2-dimethyltrimethylene carbonate

In this study, three isothioureas (ITUs), 2,3,5,6-tetrahydroimidazo[2,1-b]thiazole (ITU 1), 2,3,6,7-tetrahydro-5H-thiazolo-[3,2-a]pyrimidine (ITU 2) and 3,4,7,8-tetrahydro-2H,6H-pyrimido[2,1-b][1,3]thiazine (ITU 3) were prepared. These ITUs coupled with magnesium halides (MgX2) as the cocatalysts, cooperatively promoted the ring-opening polymerization (ROP) of several common lactones (including -valerolactone, epsilon-caprolactone, epsilon-decalactone and even of macrolactone -pentadecalactone) and 2,2-dimethyltrimethylene carbonate. These cocatalysts were found to exhibit suitable activities and ITU 2 emerged as the most active organic component. The order of activities for the magnesium halides was found to be lying in the following order: MgI2 > MgBr2 > MgCl2. The polymerizations attained high conversions (>90%) under optimal conditions, and produced linear polyesters having predictable molecular weights, narrow polydispersity indices (PDIs < 1.20) and defined end groups, which were derived from the benzyl alcohol initiator. The resulting polymers were characterized using GPC, IR, DSC, NMR and MALDI-ToF mass. The kinetic and chain extension experiments showed that the ITUs/MgX2-cocatalyzed ROPs of epsilon-caprolactone proceeded a living polymerization characteristics. Furthermore, the proposed polymerization mechanism was supposed to be a dual catalytic mechanism, and involved the activation of monomers through coordination to Lewis acids, while the initiator was activated by bases. Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.

Utilizing Amines and Carbon Disulfide to Obtain Nitrogen- and Sulfur-containing Compounds under Green Conditions: A Review

As multi-component reactions have been among the most important and advantageous methodologies in organic chemistry since 150 years ago, the present review focuses on one-pot multi-component reactions containing amines and carbon disulfide as constant starting materials along with other essential substances to afford the corresponding nitrogen-and sulfur-containing products in demand such as thiazolidine-2-thiones, 2-imino-1,3-dithiolanes, 2-substituted benzothiazoles, 1,3-thiazine-2-thiones, dithiocarbamate derivatives, and thioureas through green methodologies. This synthetic field has been widely studied throughout the last two decades to achieve such biologically active structures. The progress orientation of these reports towards green chemistry principles is reviewed from 2000 to December 2017.

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.

Ratiometric polymer probe for detection of peroxynitrite and the application for live-cell imaging

Peroxynitrite (ONOO?) is one of the sources of oxidation stress involved in many biological signaling pathways. The role of ONOO? being a double-edged sword in biological systems drives the development of effective detection tools. In this work, a boronate-based polymeric fluorescent probe PB-PVA was synthesized and the probe performance was evaluated. The probe exhibits ratiometric sensing of ONOO? in a range of 0?6 muM. There is good linear relationship between the probe fluorescence intensity ratio and ONOO? concentration. The probe also displays moderate selectivity towards ONOO? over other ROS. Moreover, it is water-soluble and possesses good biocompatibility which aids the imaging of ONOO? in living cells. These properties could make the probe a promising tool in in vitro study related to ONOO?

Antimicrobial efficacy of photodynamic therapy and light-activated disinfection on contaminated zirconia implants: An in vitro study

Background: We aimed to evaluate the antimicrobial efficacy of photodynamic therapy (PDT) and light-activated disinfection (LAD) on zirconia dental implants contaminated with three bacterial species and investigate if the PDT and LAD cause implant surface alterations. Methods: Seventy-two zirconia dental implants were contaminated with a bacterial suspension of Prevotella intermedia, Actinomyces actinomycetemcomitans, and Porphyromonas gingivalis. The implants were subsequently randomly divided into four groups (n = 12 dental implants/each) according to the decontamination protocol: Group 1 (PDT1) ? PDT (660 nm, 100 mW) with toluidine blue; Group 2 (PDT2) ? PDT (660 nm, 100 mW) with phenothiazine chloride dye; Group 3 (LAD) ? light emitting diode (LED) with toluidine blue; and Group 4 (TB) ? toluidine blue without the application of light. Implants in the positive control (PC) group were treated with a 0.2% chlorhexidine-based solution, and implants assigned to the negative control (NC) group did not undergo any treatment. Each implant was then placed in tubes containing phosphate buffered saline (PBS) and vortexed for 60 s to remove the remaining bacteria from the implant surface. After 10-fold serial dilutions, 30 mul of the suspension was plated on Brucella agar plates. After 72 h, the colony forming units (CFU) were counted. Distinctive colonies were confirmed with MALDI Biotyper. The implants were analyzed using scanning electron microscope (SEM) to evaluate the possible surface alterations due to PDT or LAD. Results: All study groups had significant reductions in the number of CFUs compared with the NC (p < 0.05). PDT1, the PDT2, and the LAD groups had the largest bacterial reduction with respect to each bacterial species separately and the total bacterial count, and they were more efficient compared with the TB group (p < 0.05). SEM analysis did not reveal any alterations of the implant surface after the treatment procedures. Conclusion: Both PDT protocols and LAD showed high and equal effectiveness in decontamination of zirconia dental implants. Do you like my blog?
