β-Lactam compounds, process for their preparation, compositions containing them and intermediates of use in their preparation are described. The β-lactam compounds have the formula
(wherein R2a represents a carboxyl esterifying group or a hydrogen atom, R3 represents a group -CnH2n- where n is an integer from 1 to 6, R' represents an azido group -N3 or an amino group -NH2 and B represents S or S→O) together with salts and zwitterionic forms thereof.
The acids, salts and metabolically labile esters are of use as antibiotics or as β-lactamase inhibitors against a range of gram-positive and gram-negative microorganisms.
描述了 β-内酰胺化合物、其制备工艺、含有这些化合物的组合物以及用于制备这些化合物的中间体。β-内酰胺化合物的化学式为
(其中 R2a 代表羧基酯化基团或氢原子,R3 代表基团 -CnH2n- 其中 n 为 1 至 6 的整数,R'代表叠氮基团 -N3 或氨基基团 -NH2,B 代表 S 或 S→O)及其盐和齐聚物形式。
这些酸、盐和代谢易变酯可用作抗生素或 β-内酰胺酶抑制剂,以对付各种革兰氏阳性和革兰氏阴性微生物。
