Derivatives of benzo-1,4-thiazine-3-carboxylic acid and the corresponding amino acid conjugates
Herein, we present the synthesis and utilization of derivatives of 4H-benzo[b][1,4]thiazine-3-carboxylic acid. These benzothiazine compounds were assembled via the coupling of aminothiols and bromopyruvates.

Microglial dynamics and ferroptosis induction in human iPSC-derived neuron-astrocyte-microglia tri-cultures. [PDF]
A tri‐culture of iPSC‐derived neurons, astrocytes, and microglia treated with ferroptosis inducers as an Induced ferroptosis model was characterized by scRNA‐seq, cell survival, and cytokine release assays. This analysis revealed diverse microglial transcriptomic changes, indicating that the system captures key aspects of the complex cellular ...

Synthesis of quinazolino‐1,3‐benzothiazine derivatives [PDF]
AbstractThe ring‐closure reactions of N‐(3,4‐dimethoxyphenylthiomethyl)‐2‐nitrobenzamide derivatives 5a,b with phosphoryl chloride gave 4‐(2‐nitrophenyl)‐2H1,3‐benzothiazine derivatives 7a,b, which on reduction yielded 4‐(2′‐aminophenyl)‐3,4‐dihydro‐2H‐1,3‐benzothiazines 8a,b.

Benzothiazines in Synthesis. A Total Synthesis of Pseudopteroxazole. [PDF]
An enantioselective total synthesis of the naturally occurring antitubercular agent pseudopteroxazole is described. The synthesis is organized around the use of a stereoselective, intramolecular addition of a sulfoximine carbanion to an alpha,beta-unsaturated ester to form an enantiomerically pure benzothiazine.

Synthesis and bioassay of azolyl benzothiazine carboxamides [PDF]
Cyclic sulfonamides (sultams) gained importance due to their potential pharmaceutical activity. Amongst these, 1,2-benzothiazine-1,1-dioxide and their derivatives represent the most familiar class of non-steroidal anti- inflammatory drugs (NSAIDs) available in the market.
