Electron-Rich Phenothiazine Congeners and Beyond: Synthesis and Electronic Properties of Isomeric Dithieno[1,4]thiazines

A series of isomeric dithieno[1,4]thiazines is accessible through an intermolecular-intramolecular Buchwald-Hartwig amination starting from dihalodithienyl sulfides. The electronic properties of dithieno[1,4]thiazine isomers differ conspicuously over a broad range depending on the thiophene-thiazine anellation: a large cathodic (340 mV) or an anodic shift (130 mV) of the redox potentials relative to corresponding phenothiazines is possible. Structure-property relationships of the dithieno[1,4]thiazine constitution derived from DFT calculations and cyclic voltammetry not only reveal increased electron density but also different delocalization of the radical cations that determines the electrochemical properties significantly. In addition, photophysical properties (absorption and emission) qualify dithieno[1,4]thiazines as promising substitutes of phenothiazine and beyond due to increased tunable electron richness.

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.

Assessment of a pretomanid analogue library for African trypanosomiasis: Hit-to-lead studies on 6-substituted 2-nitro-6,7-dihydro-5H-imidazo[2,1-b][1,3] thiazine 8-oxides

A 900 compound nitroimidazole-based library derived from our pretomanid backup program with TB Alliance was screened for utility against human African trypanosomiasis (HAT) by the Drugs for Neglected Diseases initiative. Potent hits included 2-nitro-6,7-dihydro-5H-imidazo[2,1-b][1,3] thiazine 8-oxides, which surprisingly displayed good metabolic stability and excellent cell permeability. Following comprehensive mouse pharmacokinetic assessments on four hits and determination of the most active chiral form, a thiazine oxide counterpart of pretomanid (24) was identified as the best lead. With once daily oral dosing, this compound delivered complete cures in an acute infection mouse model of HAT and increased survival times in a stage 2 model, implying the need for more prolonged CNS exposure. In preliminary SAR findings, antitrypanosomal activity was reduced by removal of the benzylic methylene but enhanced through a phenylpyridine-based side chain, providing important direction for future studies (C) 2017 Elsevier Ltd.

Experimental and Quantum Chemical Analysis of New Pyrimidothiazine Derivative as Corrosion Inhibitor for Mild Steel in 1.0 M Hydrochloric Acid Solution

The corrosion inhibition efficiency of pyrimidothiazine compound, namely: 8-ethyl-3-hydroxy-4,6-dioxo-2-(p-tolyl)-4,6-dihydropyrimido [2,1-b][1,3] thiazine-7carbonitrile (EHDPTC), was evaluated in the system steel/1 M HCl. This compound is investigated experimentally using weight loss, potentiodynamic polarization curves and electrochemical impedance spectroscopy. The results showed that the inhibition mechanism involves blockage of the steel surface by the inhibitor molecules by a Langmuir-type adsorption process and that the structure of molecule plays an important role in the inhibition efficiency of the synthesized inhibitor. The thermodynamic parameters of activation and adsorption have been calculated and discussed in detail. Furthermore, the quantum chemical parameters have been calculated and discussed in view of the results earlier reported.

Differential activity of methylene blue against erythrocytic and hepatic stages of Plasmodium

Background: In the context of malaria elimination/eradication, drugs that are effective against the different developmental stages of the parasite are highly desirable. The oldest synthetic anti-malarial drug, the thiazine dye methylene blue (MB), is known for its activity against Plasmodium blood stages, including gametocytes. The aim of the present study was to investigate a possible effect of MB against malaria parasite liver stages. Methods: MB activity was investigated using both in vitro and in vivo models. In vitro assays consisted of testing MB activity on Plasmodium falciparum, Plasmodium cynomolgi and Plasmodium yoelii parasites in human, simian or murine primary hepatocytes, respectively. MB in vivo activity was evaluated using intravital imaging in BALB/c mice infected with a transgenic bioluminescent P. yoelii parasite line. The transmission-blocking activity of MB was also addressed using mosquitoes fed on MB-treated mice. Results: MB shows no activity on Plasmodium liver stages, including hypnozoites, in vitro in primary hepatocytes. In BALB/c mice, MB has moderate effect on P. yoelii hepatic development but is highly effective against blood stage growth. MB is active against gametocytes and abrogates parasite transmission from mice to mosquitoes. Conclusion: While confirming activity of MB against both sexual and asexual blood stages, the results indicate that MB has only little activity on the development of the hepatic stages of malaria parasites.
