  3. Antibiotic Bacterial
  4. Colistin

Colistin is an orally active polypeptide antibiotic. Colistin has excellent activity against various Gram-negative rod-shaped bacteria, including multidrug-resistant Pseudomonas aeruginosa, Acinetobacter baumannii and Klebsiella pneumoniae. Colistin is associated with nephrotoxicity. Colistin can be used for the research of infections caused by Gram-negative bacilli.

The free form of the compound is prone to instability, it is advisable to consider the stable salt form (Colistin sulfate) that retains the same biological activity.

    제품 설명

    Colistin is an orally active polypeptide antibiotic. Colistin has excellent activity against various Gram-negative rod-shaped bacteria, including multidrug-resistant Pseudomonas aeruginosa, Acinetobacter baumannii and Klebsiella pneumoniae. Colistin is associated with nephrotoxicity. Colistin can be used for the research of infections caused by Gram-negative bacilli[1][2].

    In Vivo

    Colistin (16 mg/kg/day, i.p.) shows the enrichment of cell cycle arrest genes and suggests that injury or cellular stress caused by colistin is acting through p53 to inhibit cell cycle progression[1].
    Colistin (16 mg/kg/day, i.p.) has elevated blood urea nitrogen (BUN), creatinine, and pathologic evidence of acute tubular necrosis and apoptosis[1].

    MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
