Antibiotics

An antibiotic is a chemical substance that kills bacteria, protozoa or fungi or inhibits their proliferation. Due to this antimicrobial function antibiotics are used as therapeutics in case of bacterial infections. In life sciences, antibiotics are often used for selecting clones after transformation of recombinant DNA. This method uses resistance genes that are part of the transformed DNA. Alternatively Antibiotics are used as inhibitors to specifically shut down specific targets, like enzymes or receptors of bacteria and cells. Here you’ll find an extensive portfolio of antibiotics from ampicillin to zelkovamycin for use in the selection of resistant bacteria or inhibition of cells.

Mitomycin C
Mitomycin C

Item number: Cay11435-10

Mitomycin C (MMC) is an antitumor antibiotic that was discovered as a fermentation product of S. caespitosus. As an alkylating agent, its activity depends on reductive activation either through low pH or DT-diaphorase or NADH cytochrome c reductase. Activated MMC crosslinks double stranded DNA and is widely used as a tool to selectively inhibit DNA synthesis and...

Amphotericin B
Amphotericin B

Item number: Cay11636-500

Amphotericin B is a classic antifungal polyene macrolide that has been used in the treatment of systemic fungal infections, primarily caused by C. albicans, A. fumigatus, and parasitic L. protozoans, as well as in tissue culture to prevent fungi from contaminating cell cultures. Amphotericin B binds with ergosterol, the main component of fungal cell membranes, forming a...

Sulfasalazine
Sulfasalazine

Item number: Cay15025-5

Sulfasalazine is a prodrug of the anti-inflammatory agent 5-aminosalicylic acid that is covalently linked to the antibiotic sulfapyridine by an azo bond. This bond is rapidly cleaved by bacteria in the terminal ileum and colon, thus releasing the active anti-inflammatory component. It has long been used in treatment of inflammatory bowel disease and rheumatoid arthritis...
