Luminescence of Leuco-Thiazine Dyes
Journal of Fluorescence, 2003 Details 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.

Multicomponent Synthesis of Dihydropyrimidines and Thiazines
Chemistry – A European Journal, 2006AbstractA broad range of differently substituted dihydropyrimidines and thiazines can be efficiently prepared by using a four‐component reaction between phosphonates, nitriles, aldehydes, and iso(thio)cyanates. The scope and limitations of this multicomponent reaction are fully described. Variation of all four components has been investigated.

Thiazine, Antibiotic, Bilirubin Adducts
Xenobiotica, 19891. Electron charge transfer interactions of some phenothiazine derivatives with aminoglycoside antibiotics, beta-lactams and penicillin-related antibiotics and bilirubin were investigated with alternating current titrations. 2. Neither the beta-lactams nor penicillin-related drugs interacted. 3.

1990
Publisher Summary This chapter discusses the monocyclic thiazines and their functionalized derivatives. The sp 3 -hybridized saturated carbon bearing the extra hydrogen was indicated by a number placed after those for the heteroatoms. Hence, 2H-1,3-thiazine was named 1,3,2-thiazine. The chapter discusses the synthesis of 1,3-thiazines.

Chemistry of Heterocyclic Compounds, 2016
Thiazines represent an important class of heterocyclic compounds due to their valuable biological properties. For example, some derivatives of thiazine are cannabinoid receptor agonists, also they can act as an antihypotensive, antitubercular, and antibacterial agents.

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 ...

The binding of thiazines by proteins and nucleic acid
Archives of Biochemistry and Biophysics, 1952Abstract Binding of the red thiazine dyes, phenothiazone and thionol, by plasma albumin, yeast nucleic acid, and thymus nucleoprotein has been observed spectrophotometrically. Binding constants have been evaluated by the equilibrium dialysis method. The results indicate that binding of these compounds is not extensive: relatively few binding sites ...

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.

The Chemical Analysis of Thiazin Eosinates
Stain Technology, 1929The constituents of blood stains are normal eosinates of the thiazin series of dyes. Methods are outlined for the chemical examinations of blood stains which are based upon the complete reduction of all dye components present in buffered solutions of limited acidity, and the reduction of their thiazin components alone in strongly acid solutions ...
