Thiazine, Antibiotic, Bilirubin Adducts

Xenobiotica, 1989
1. 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.

Multicomponent Synthesis of Dihydropyrimidines and Thiazines

Chemistry – A European Journal, 2006
AbstractA 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.

1,3-Thiazines

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.

Synthesis of 4H-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, 1961
DURING 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, 2000
Abstract 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, 1992
Abstract 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.
