Microwave-Assisted Synthesis of 2-Substituted 2-Thiazolines and 5,6-Dihydro-4 H -1,3-thiazines

An efficient and general method for the synthesis of 2-substituted thiazolines and 5,6-dihydro-4 H -1,3-thiazines is developed via microwave-assisted ring closure of omega -thioamidoalcohols promoted by ethyl polyphosphate (PPE). The cyclization reaction involves an S (N) 2-type mechanism and features the advantages of very short reaction times, high yields and a predictable stereochemical outcome. The acyclic precursors are prepared in high overall yields by an improved diacylation-thionation-saponification sequence from commercially available omega -aminoalcohols. The whole process is metal-free and operationally simple.

Organic Synthesis with N-Heterocyclic Carbenes of Indazole: Synthesis of Benzo(thio)imidates, Benzo[d][1,3]thiazines and Quinazoline-4-thiones

The N-heterocyclic carbenes of indazole, generated by deprotonation of indazolium salts, proved to be versatile starting materials for organic synthesis. They undergo ring-opening reactions to generate ketenimines which readily add thiols thus affording what are, to the best of our knowledge, the first examples of 2-anilinobenzothioimidates. Water converts the ring-opened intermediates into functionalized 2-anilinobenzamides which can be thionated with Lawesson’s reagent and subsequently cyclized with formaldehyde and propionaldehyde, respectively, to give benzo[d][1,3]thiazines and quinazoline-4-thiones. The outcome of the cyclization depends upon the thiobenzamide substitution pattern.

Access to SCN-containing thiazolines via electrochemical regioselective thiocyanothiocyclization of N-allylthioamides

An electrochemical thiocyanothiocyclization of N-allylthioamides has been developed for the synthesis of SCN-containing 2-thiazolines. This method provides a green and efficient approach to generate 5-exo-cyclization 2-thiazolines with a broad substrate scope and good yields. In addition, 6-endo-cyclization isothiocyanato thiazines are formed regioselectively when cyclic thioamides are used as reactants. The reaction is easy to proceed under catalyst-, additive- and oxidant-free conditions.

6-Substituted 9-fluoroquino[3,2-b]benzo[1,4]thiazines display strong antiproliferative and antitumor properties

6-Substituted 9-fluoroquino[3,2-b]benzo[1,4]thiazines – a new type of tetracyclic azaphenothiazines -were obtained from of 6H-9-fluoroquinobenzothiazine by the introduction of appropriate substituents to the thiazine nitrogen atom (alkyl, aminoalkyl, amidoalkyl, sulfonamidoalkyl and nitrogen half-mustard groups). The compounds displayed differential cytotoxic as well as antiproliferative actions against human peripheral blood mononuclear cells (PBMC) stimulated with phytohemagglutinin A (PHA). In addition, they suppressed lipopolysaccharide (LPS)-induced tumor necrosis factor alpha (TNF-alpha) production by whole blood human cell cultures. Two compounds (4 and 15, with the propargyl and methanesulfonamidopropyl groups) were selected for further experiments because of lack of cytotoxicity and strong antiproliferative actions. Compound 4 showed strong suppressive actions on growth of L1210, SW948, A-431 and CX-1 tumor cell lines which were close to those of cisplatin, the reference drug (e.g. GI(50) of 2.28 mu g/mL vs. 1.86 mu g/mL for L1210 cells). Further, the compound appeared to be equally effective as cyclosporine A (CsA) in the inhibition of human two-way mixed lymphocyte reaction (MLR). The compound did not significantly inhibit interleukin 2 (IL-2)-induced growth of CTLL-2 cell line. In addition, inhibition of prostaglandin (PG) synthesis by indomethacin or block of PG receptors did not interfere with the inhibitory effect of the compound on PHA-induced cell proliferation. Therefore, it is likely that the compound acts by inhibiting cell cycle as proposed for other phenothiazines. Further studies are required for the elucidation of the mechanism of action and therapeutic utility of these compounds in more advanced in vivo models. (C) 2014 Elsevier Masson SAS.

An operational study comparing microscopes and staining variations for tuberculosis LED FM

SETTING: Tuberculosis control projects, Damien Foundation Bangladesh. OBJECTIVES: To compare transmitted fluorescence (Olympus CX21 (TM)/FRAEN FluoLED (TM)) with epi-fluorescence (Zeiss Primostar iLED (TM)) light-emitting diode microscopes (LED-FM) and various auramine staining and destaining/counterstaining techniques for the detection of acid-fast bacilli. DESIGN: Multicentre blinded reading of routine smears on both types of microscopes using different staining techniques in multiple phases. LED-FM rechecking of discordant series with and without restaining to calculate operating characteristics. RESULTS: Among 64 874 smears, both instruments detected 9.6% positives. Compared to the standard technique, the stronger auramine-O formulation did not perform better. Thiazine red counterstaining tended to yield more false-positive as well as false-negative errors. Combined destaining/counterstaining (sensitivity 93%, positive predictive value [PPV] 98%) proved significantly less effective. Both destaining with 1% hydrochloric acid (HCl) and 10% alcohol and the standard 0.5% HCl and 70-95% alcohol were equally accurate (sensitivity 95-96%, PPV 99%). The sturdiness of the microscopes in field conditions was sub-optimal: only 5/16 instruments did not break down. CONCLUSIONS: Both microscopes performed equally well. The standard staining technique is as good as the more complicated and expensive variations. A destaining solution containing only 10% alcohol works perfectly well. The inferior quality of LED-FM microscope components is an obstacle to FM expansion.

Environment effects on the nonlinear absorption properties of Methylene blue under different power of excitation beam

In this paper, the nonlinear optical absorption properties of Methylene blue solutions were studied by open aperture Z-scan technique under a continuous-wave laser irradiation with various input powers. The experimental results show that the mechanism of nonlinear absorption and the calculated coefficients depend highly onthe molecular surrounding media properties and the nature of intermolecular interactions. From the experimental results, the contributions of various intermolecular interactions were determined as well. Exploiting these results, it is possible to determine the effective media polarity parameters on the nonlinear responses of optical materials. According to the experimental results, by increasing of excitation beam power, the strong hydrogen bonds with high contributions increase the third order nonlinear responses of Methylene blue molecules.

A new route for the synthesis of pyrimido[2,1-b][1,3]thiazine ring system

A simple and efficient pathway to conjugate monosaccharides to thienopyrimidines via click chemistry establishing a 1,2,3-triazole linker was reported. Potential pharmaceutical interest is envisaged for the expected target products. Starting from a 2-isothiocyanate-thiophene-3-carboxylate, an allylthiourea was obtained with allylamine, cyclized and S-propargylated to give a thienopyrimidine-alkyne core. Click reaction with tetraacetyl-1-azidoglucose was successful to give the target conjugate with one sugar unit. When propargylamine was used in the first step, the expected thiourea cyclized via the alkyne moiety leading to pyrimido[2,1-b][1,3]thiazine.
