Synthesis and biological activity of substituted 4H-1,4-benzothiazines, their sulfones, and ribofuranosides. Nucleosides, nucleotides & nucleic acids, 2013, Volume: 32, Issue:2 The present article describes the synthesis of new 4H-1,4-benzothiazines via condensation and oxidative cyclization of substituted 2-aminobenzenethiols with β-diketones/β-ketoesters in dimethyl sulfoxide. The oxidation of these synthesized 4H-1,4-benzothiazines with 30% hydrogen peroxide in glacial acetic acid yielded 4H-1,4-benzothiazine sulfones and the reaction of these synthesized benzothiazines with sugar (β-D-ribofuranose-1-acetate-2,3,5-tribenzoate) afforded the new ribofuranosides. These compounds were evaluated for their antioxidant and antimicrobial activities (using broth microdilution method). The structural assignments of the synthesized compounds were made on the basis of elemental analyses and spectroscopic data.

Synthesis and antioxidant activity of quinolinobenzothiazinones. European journal of medicinal chemistry, 2010, Volume: 45, Issue:10 A new series of structurally diverse quinolinobenzothiazinones has been synthesized with the annulation of heterocyclic structural pharmacophores. The synthesized quinolinobenzothiazinones have been evaluated for their antioxidant (LPO & GSH) and radical scavenging activities (DPPH and ABTS assays). Topics: Animals; Antioxidants; Benzothiazoles; Biphenyl Compounds; Free Radical Scavengers; Free Radicals; Lipid Peroxidation; Mice; Picrates; Quinolines; Sulfonic Acids; Thiazines	2010
