This paper discusses the synthesis of privileged structures 4H-benzo[1,4]thiazin-3-one and 1,1-dioxo-1,4-dihydro-2H-1lambda6-benzo[1,4]thiazin-3-one derivatives in a parallel solution-phase manner using 1,5-difluoro-2,4-dinitrobenzene. Each scaffold possesses four diversity points. A cheap and efficient oxidant, urea-hydrogen peroxide (UHP), was applied for the introduction of the

The UL9 gene of herpes simplex virus type 1 (HSV-1) encodes an origin binding protein (OBP). It is an ATP-dependent DNA helicase and a sequence-specific DNA-binding protein. The latter function is carried out by the C-terminal domain of OBP (DeltaOBP).
