Abstract magnified imageThe method of pyrimidine ring fusion at the [c] side of benzothiazines based on the reaction of their chloroaldehyde derivatives with amidines is described. Formation of the structural isomers of reaction products was investigated, and regioselectivity of heterocyclization reactions was shown.

Quinolones are a widely used class of antibacterial agents characterized by overall favourable pharmacokinetic and pharmacodynamic characteristics. Unfortunately, both nosocomial and community acquired resistances to these agents are increasing. Thorough structure–activity relationship (SAR) studies have demonstrated that even drastic manipulation of ...

3,4-Dihydro-2,1-benzothiazine 2,2-dioxides were easily obtained in good yields by the reaction of N-methyl 2-arylethane-sulfonamides with 1,3-diiodo-5,5-dimethylhydantoin (D1H) under irradiation with a tungsten lamp. When N-benzyl 2-phenylethane-sulfonamide was treated with DIH under the same conditions, the corresponding N-benzyl 3,4-dihydro-2,1 ...

Diabetes mellitus (DM) is a metabolic disorder characterized by frequent urination, hunger and high blood sugar level. α-glucosidase inhibitors are considered as a frontline treatment for the DM. This research article deals with the identification of benzothiazine derivatives as α-glucosidase inhibitors through in-silico techniques and then the ...
