Photo-Sensitivity of Thiazine Leucobases
Nature, 1961DURING the course of experiments designed to investigate the staining of nucleic acid in histological sections, I happened to gather together on one bench a number of solutions of basic dyes reduced to their colourless sulphite leucobase. These included methyl green, basic fuchsin and a series of thiazines, namely, thionin, azure A, B and C, and ...

N,N-DIALKYLAMINOALKYL SUBSTITUTED QUINOBENZO[1,4]THIAZINES AND DIQUINO[1,4]THIAZINES#
Phosphorus, Sulfur, and Silicon and the Related Elements, 2000Abstract 12-(N,N-Dialkylaminoalkyl)quino[1,4]benzothiazines 2c-2g were obtained by alkylation of 12H-quino[1,4]benzothiazines 2a and 2b with N,N-dialkylaminoalkyl chlorides in dioxane. 14H-Diquino [1,4]thiazine 4a was unreactive in the same conditions.

4H-1,4-THIAZINES ET 2H-1,4-THIAZINES A PARTIR DE 2-(DIALKYLHYDRAZONO)-THIOACETOPHENONES
Phosphorus, Sulfur, and Silicon and the Related Elements, 1992Abstract 2-(Dialkylhydrazono)thioacetophenones 1 react with N-phenylmaleimide and lead via [4 + 2] cycloaddition to 4-amino-3,4-dihydro-2H-1,4-thiazines 2 which are easily converted into 4H-1,4-thiazines 3. Reaction with 1,4-naphthoquinone leads directly to 4H-1,4-thiazines 4.

Quinoxalino[2,3-b]-1,4-thiazines
Chemistry of Heterocyclic Compounds, 1971Quinoxalino[2,3-b]-1,4-thiazines were obtained by the reaction of 2-aminoquinoxaline-3-thione and its 6,7-dimethyl derivative with α-halocarbonyl compounds. Hydrolysis of these compounds in alkaline and acid media gave 2-amino-3-quinoxalone and quinoxaline-2,3-dione. The IR and UV spectra are presented.

Dielectric properties of thiazine derivatives
Electrochimica Acta, 1968Abstract The thiazine derivatives promethazine, chlorpromazine, trimeprazine, prochlorperazine, trifluoperazine, methotrimeprazine and thioproperazine exhibit similar dielectric behaviour, and all except the last two are subject to severe supercooling.

Luminescence of Leuco-Thiazine Dyes
Journal of Fluorescence, 2003Details of the novel luminescence of the leuco forms of the thiazine dyes, methylene blue and thionine, are reported, including their emission maxima, quantum yields and lifetimes of the luminescence. Other work shows that this luminescence is independent of reducing agent type and solution pH and is a common feature of most thiazine dyes.

The Journal of Organic Chemistry, 1999
The reaction of N-(2-chloroethyl)diisopropylamine 1a with S2Cl2 allows the selective one-pot preparation of the tricyclic 4-(2-chloroethyl) bisdithiolothiazines 2-4 or, by addition of phosphorus pentasulfide at a late stage in the reaction, of the dithiolothiazine 5. The chloroethyl derivative 2 is also obtained from (2-diisopropylamino)ethanethiol 1b,
