4H-3,1-Benzoxazin-4-one compounds represented by
(wherein R represents a hydrogen atom or an alkyl group, A represents an amino acid residue or a peptide containing 2 to 3 amino acid residues (provided that side chains of these amino acid residues may be protected by protective groups), X represents an alkyl group, a fluoroalkyl group, OR1 or NHR1 (wherein R1 represents an alkyl group) and Y represents an amino group-protective group) and their salts are disclosed. They show an excellent inhibitory action on serine protease, particularly human leukocyte elastase, thus being useful as the component of elastase-inhibiting drugs.
