Jl. Gilmore et al., SYNTHESIS AND EVALUATION OF 2-ARYL-4H-3,1-BENZOXAZIN-4-ONES AS C1R SERINE-PROTEASE INHIBITORS, Bioorganic & medicinal chemistry letters, 6(6), 1996, pp. 679-682
A series of 2-aryl-4H-3,1-benzoxazin-4-ones have been synthesized and
tested for inhibitory activity against Clr serine protease. Compounds
were found that were equipotent and more selective than the reference
compound FUT-175.
