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.
4H-3,1-苯并恶嗪-4-酮化合物,其代表为
(其中 R 代表氢原子或烷基,A 代表氨基酸残基或含有 2 至 3 个氨基酸残基的多肽(条件是这些氨基酸残基的侧链可由保护基团保护),X 代表烷基、氟烷基、OR1 或 NHR1(其中 R1 代表烷基),Y 代表氨基保护基团)及其盐类。它们对丝氨酸蛋白酶,特别是人类白细胞弹性蛋白酶有很好的抑制作用,因此可用作弹性蛋白酶抑制药物的成分。
