描述

产品介绍 Ampicillin is reported as slightly soluble in water, practically insoluble in alcohol, chloroform, ether and fixed oils but soluble in dilute acids or bases. The solution should not be autoclaved; a stock solution should be sterilized through filtration and stored frozen, where it will be stable for months.
别名 氨苄青霉素钠 ;氨苄西林钠;D-(−)-α-Aminobenzylpenicillin sodium salt Ampicillin sodium salt
生化机理 β-内酰胺类抗生素,具有连接到青霉素结构上的氨基侧链。青霉素衍生物,通过灭活细菌细胞膜内表面上的转肽酶,抑制细菌细胞壁的合成(肽聚糖交联)。仅对生长的 Escherichia coli 具有杀菌作用。抗性方式:通过 β-内酰胺酶使氨苄西林的 β-内酰胺环分裂。抗菌谱:革兰氏阴性和革兰氏阳性细菌。
应用 半合成的青霉素,抗革兰氏阳性及阴性菌。
属β-内酰胺酶抗生素,氨基基团链连接到青霉素结构上。属青霉素衍生物,依靠在细菌细胞膜的内层面使转肽酶(transpeptidases)失活抑制细菌细胞壁的合成。
