    摘要： Novel 2-amino-4H-3,1-benzoxazin-4-ones represented by the formula
    and the pharmaceutically acceptable esters and salts thereof wherein R' is hydrogen or lower alkyl;

    R 2 and R 3 are each independently hydrogen, halo, lower alkyl, hydroxy, lower alkoxy, lower thioalkyl, -N0 2 , -N(R') 2 , -NR'COR', -NHCON(R') 2 or -NHCOOR',
    with the proviso that at least one of R 1 , R 2 and R 3 is not hydrogen when X is NHR or NR'COR"; and
    X is a radical chosen trom
    in which:
    R is lower alkyl, lower alkenyl, lower alkynyl, optionally substituted lower cycloalkyl or optionally substituted phenyl lower alkyl;
    each R' is independently hydrogen or lower alkyl, or lower alkenyl or lower alkynyl where the unsaturated bond is at least one carbon removed from the O or N atom;
    each R" is independently R, lower alkoxy, NHR' or AOR'; and
    A is an amino acid residue, or a peptide of 2 to 3 amino acid residues, are useful as enzyme inhibitors in animals.
