Synthesis, characterization and antimicrobial activity of new chalcones and their 6-aryl-4-(2,5-dichlorothiophen-3-yl)-6H-1,3-thiazin-2-amine derivatives

Chalcones (5a-h) were prepared in high yields via the condensation of 3-acetyl-2,5-dichlorothiophene (3) with aryl aldehydes (4a-h). The reaction of the resulting chalcones with thiourea in the presence of a catalytic amount of hydrochloric acid provided the 1,3-thiazin-2-amine derivatives (6a-g) in moderate yields. All new compounds were characterized by extensive NMR analysis data, including 1D NMR experiments (H-1 and C-13) and 2D NMR experiments (COSY, HMBC, HSQC), as well as ESIMS and HRESIMS data. The newly synthesized compounds were evaluated for their biological activities, which demonstrate a very good to low bioactivities as antibacterial and antifungal, respectively. [GRAPHICS] .

Synthesis of the Fused Tetracyclic Thiazinan-4-one Derivatives and Their Anti-tumor Activitiy

The benzothiazin-4-one intermediates were prepared by the one-pot three-components condensation from the N-Boc-L-prolinal 1, amino acid ethyl/methyl ester hydrochlorides 2a similar to 2d, and mercaptobenzoic acids 3a similar to 3b. After removal of Boc, the target novel fused tetracyclic thiazinan-4-one derivatives 6 similar to 11 were afforded by the intramolecular cyclo- amidation reaction. The absolute configurations of the newly generated chiral carbon (1-C) were determined by the coupling constants of H-1 and H-2 and the X-ray crystallographic structures. The tetracyclic alkaloids were examined for their anti-proliferative activity against Hela and A549 tumor cells. The results showed that some compounds could moderately inhibit the growth of Hela cells, and among them, (13aR, 13bR)-1,2,3,13b-tetrahydrobenzo[e]pyrrolo[2′, 1′: 3,4] pyrazino[2,1b][1,3] thiazine-5,8(6H, 13aH)-dione (6b) was the best one with the IC50 value of 9.50 mu mol/L. However, all the compounds showed no anti-tumor activity against A549.

An Approach to Polysubstituted Triazipines, Thiadiazoles and Thiazoles Based on Benzopyran Moiety Through The Utility of Versatile Hydrazonoyl Halides as In Vitro Monoamine Oxidase Inhibitors

The chromene compound 1 is used as a key intermediate for synthesis of new heterocyclic compounds, and it reacted with hydrazonoyl chlorides in presence of TEA to give the amidrazone derivatives 3a, 3b, 3c, 3d, 3e, 3f, 3g, 3h, which were cyclized to the corresponding triazepines 5a, 5b, 5c, 5d, 5e, 5f, 5g, 5h on boiling with sodium ethoxide. Conversion of compound 1 to the methylthiocarbamate derivative 6 was performed through its reaction with carbon disulfide and KOH followed by treatment with methyl iodide. Compound 6 reacted with hydrazonoyl chlorides in presence of TEA to give thiadiazoles 8a, 8b, 8c, 8d, 8e, 8f, 8g. In addition, chromene 1 combined with aminodithiocarbamic acid in DMF under reflux to furnish the thiosemicarbazide derivative 9, which in turn interacted with several hydrazonoyl chlorides to give the thiazole derivatives 11a, 11b, 11c, 11d, 11e. The structures of the prepared compounds were confirmed from their spectroscopic data and elemental analysis. The synthesized compounds were tested against both monoamine oxidase (MAO)-A and MAO-B and corrected to analyses showed good inhibitory activities especially against MAO-A.

Novel temperature-activated humidity-sensitive optical sensor

A novel, colorimetric, temperature-activated humidity indicator is presented, with a colour change based on the semi-reversible aggregation of thiazine dyes (esp. methylene blue, MB) encapsulated within the polymer, hydroxypropyl cellulose (HPC). The initially purple MB/HPC film is activated by heat treatment at 370 degrees C for 4 s, at which point the film (with a colour associated with that of a highly aggregated form of MB; lambda(max) = 530 nm) becomes blue (indicating the presence of monomeric and dimeric MB; i.e. with lambda(max) = 665; 605 nm respectively). The blue, heat-treated MB/HPC films respond to an ambient environment with a relative humidity (RH) exceeding 70% at 21 degrees C within seconds, returning to their initial purple colour. This colour change is irreversible until the film is heat-treated once more. When exposed to a lower RH of up to ca. 47%, the film is stable in its blue form. In contrast, a MB/HPC film treated only at 220 degrees C for 15 s also turns a blue colour and responds in the same way to a RH value of ca. 70%, but it is unstable at moderate RH 37-50% values, so that it gradually returns to its purple form over a period of approximately 6 h. The possible use of the high heat-treated MB/HPC humidity indicator in the packaging of goods that cannot tolerate high RH, such as dry foods and electronics, is discussed. (C) 2016 Elsevier B.V.

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.
