There are disclosed a compound having the following formula:
in which R' denotes an aromatic group; Z represents a group
(wherein R' denotes hydrogen, a salt forming cation or a protective group for carboxylic acid, and R' denotes hydrogen or a residue of a nucleophilic compound); and X' and X2 each represent hydrogen or a halogen atom, provided that both X' and X2 cannot represent hydrogen at the same time; processes for preparing the same; and an intermediate compound useful for preparing the same.
The above mentioned compound has a broad antibacterial spectrum and shows strong antibacterial activities against not only gram-positive bacteria but also the gram-negative bacteria, particularly the resistive gram-negative bacteria.
公开了一种具有下式的化合物:其中 R'表示芳香基团;Z 表示一个基团(其中 R'表示氢、形成盐的阳离子或羧酸的保护基团,R'表示氢或亲核化合物的残基);X'和 X2 各自表示氢或卤素原子,但 X'和 X2 不能同时表示氢;制备上述化合物的工艺;以及制备上述化合物的中间化合物。 上述化合物具有广阔的抗菌谱,不仅对革兰氏阳性菌,而且对革兰氏阴性菌,特别是抵抗性革兰氏阴性菌都有很强的抗菌活性。
