Design, synthesis and biological evaluation of substituted 2-amino-1,3-thiazine derivatives as antituberculosis and anti-cancer agents

A series of substituted 2-amino-1,3-thiazines were synthesized as amides (9a-9i), carbamates (9j-9m), sulfonamides (9n-9o) and urea derivatives (9p-9q) by treating the compound 7 with acid chlorides (8a-8i), chloroformates (8j-8m), sulfonyl chlorides (8n-8o) and isocyanates (8p-8q) respectively. The synthesized compounds (9a-9q) were screened for antituberculosis activity against Mycobacterium tuberculosis H(37)Rv ATCC 27294 and the results show that some of these derivatives possess good activity against Mycobacterium tuberculosis H(37)Rv ATCC 27294. A few also display promising cytotoxic activity against human breast cancer MCF-7 and human esophageal cancer EC-9706 cell lines. Regarding both biological profiles 9b, 9m and 9h are the most active for anti-cancer, anti-TB activity. [GRAPHICS] .

One-Pot Multicomponent Synthesis and Anticancer Activity of 1,3-Cyclopentathiazine and Pyrimidothiazine Derivatives

Novel 1,3-cyclopentathiazine and pyrimidothiazine derivatives were synthesized starting from 7-benzyl-4-phenylcyclopenta[d][1,3]thiazin-2-amine (CTA) prepared by a one-pot multicomponent reaction of cyclopentanone, benzaldehyde, and thiourea. Cyclocondensation of CTA with benzylidenemalononitrile gave a pyrimidothiazine. Oxidation of cyclopentathiazine with hydrogen peroxide afforded the corresponding epoxide, while its alkylation with ethyl iodide yielded anN-ethyl derivative. Cyclopentylidenemalononitrile was reacted with formaline and carbon disulfide to obtain pyridine-4-carbonitrile and thiapyrane, respectively, and the reactions of cyclopentylidenemalononitrile with aryl isocyanate and aryl isothiocyanate gave condensed diimino-substituted cyclopentanaphthyridine-1,6-dione and dithiaacenaphthylene-3,8-diylidedibenzamide, respectively. Heating cyclopentanone with benzoyl isothiocyanate and benzoyl chloride produced a sulfide derivative and an enolic dione, respectively. The structures of the newly synthesized compounds were confirmed by spectral analysis, and some products were screened for anticancer activity.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 103-47-9 is helpful to your research. Category: thiazines.

Spectral Study on Association of Thiazine Dyes with Anionic Polymers

Feasible method of quantitative determination of anionic polymers in aqueous solutions was described using poly(styrene sulfonate) and poly(acrylate) sodium salts as an example. The method consists in absorbance measurements while titrating with thiazine dye. Volume of dye solution needed to attain specified value of absorbance is linearly dependent on polymer concentration. Optimal wavelengths are 666nm and 640nm for Methylene Blue dye and Toluidine Blue dye, respectively. Calibration plots are straight lines (r(2) > 0.99) ensuring good accuracy of the method developed. Range of measurable concentrations is dependent on chosen value of end-point absorbance.

Synthesis and antioxidant activity of some 1-aryl/aralkyl piperazine derivatives with xanthine moiety at N4

Piperazine nucleus is one of the most important heterocyclic systems exhibiting remarkable pharmacological activities. Thus, in the current study six new aryl/aralkyl substituted piperazine derivatives, containing methylxanthine moiety were synthesized and their structures were confirmed by IR and H-1 NMR analysis. All compounds were in vitro screened for their activity as antioxidants using DPPH (2,2 ‘-Diphenyl-1-picrylhydrazyl), ABTS (2,2 ‘-azinobis-(3-ethylbenzo thiazine-6-sulfonic acid)) and FRAP (ferric reducing/antioxidant power) methods. The antioxidant activity of the studied compounds against lipid peroxidation was also measured. The highest antioxidant activity was demonstrated by compound 3c. It is obvious that the presence of a hydroxyl group in the structure is essential for the antioxidant properties and should be taken into consideration in further design of structures with potential antioxidant properties.

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.

N-Radical-Initiated Cyclization through Insertion of Sulfur Dioxide under Photoinduced Catalyst-Free Conditions

A N-radical-initiated cyclization involving the sulfonylation of unactivated alkenes through insertion of sulfur dioxide in the presence of visible light under catalyst-free conditions is accomplished. A range of sulfonated 3,4-dihydro-2H-pyrroles can be generated in good yields under photoinduced sulfonylative conditions. Additionally, the corresponding 2-(3,4-dihydro-2H-pyrrol-2-yl)methylsulfonyl-1-arylethanones can be easily converted to 3,4-dihydro-2H-1,4-thiazine 1,1-dioxides. This photoinduced transformation occurs efficiently at room temperature under catalyst-free conditions, and various functional groups can be tolerated. A tandem radical process is involved through the iminyl radical-mediated cyclization with the insertion of sulfur dioxide; this process shows high efficiency and good selectivity.

Nonlinear absorption of some thiazine, xanthene, and carbocyanine dyes

The saturated and two-photon absorption of various classes of heterocyclic dyes [thiazine (thionine), xanthene (erythrosine), and carbocyanine (3,3′-di-(gamma-sulfopropy1)-4,4′,5,5′-dibenzo-9-ethylthiacarbocyaninebetaine pyridinium salt, DEC)] possessing optical absorption in the 500-680 nm range were measured at the wavelengths of 1064 and 532 nm using nanosecond (10 ns) and picosecond (40 ps) pulses and z-scan technique. It was shown that reverse saturated absorption unlikely plays important role in those dyes. We defined the two-photon absorption coefficients of thionine and erythrosine at 1064nm using 40 ps pulses (0.8 x 10(-11) and 1.0 x 10(-11) cmW(-1) respectively). The concurrence of saturated absorption and two-photon absorption was analyzed in the case of thionine and erythrosine using various models. It was suggested that dimerization of those dyes significantly suppresses the nonlinear optical response in the case of both 10 ns and 40 ps pulses of 532 nm radiation. At the same time it was found that, in the case of 532 nm pulses, the monomers of thionine participate in the processes of saturated absorption and two-photon absorption, while J-aggregates of DEC show predominantly two-photon absorption.
