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 throμgh filtration and stored frozen, where it will be stable for months.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。
Information
Ampicillin is a beta-lactam antibiotic that is part of the aminopenicillin family.
In vitro
Belonging to the penicillin group of beta-lactam antibiotics, ampicillin is able to penetrate Gram-positive and some Gram-negative bacteria. Ampicillin acts as a competitive inhibitor of the enzyme transpeptidase, which is needed by bacteria to make their cell walls. Ampicillin inhibits the third and final stage of bacterial cell wall synthesis in binary fission, which ultimately leads to cell lysis.
