General description

Cecropin B is an antimicrobial peptide present in the hemolymph of the silk moth, Hyalophora cecropia. It is a member of the Cecropin class and possesses an α-helix-like structure. 

Chemical structure: peptide

Application

Cecropin B has been used as an antibiotic peptide to study its cytotoxic potential in breast adenocarcinoma and mesothelioma cell lines. It has also been used as an antimicrobial peptide to test the susceptibility of the Photorhabdus variants in minimal inhibitory concentration (MIC) assays.

Biochem/physiol Actions

Antibacterial peptide

Antibacterial peptide originally identified in moths (Hyalophora cecropia) and later in pig intestine.

Cecropin B is known for its antimicrobial activity. It displays antitumor effects in hepatocellular carcinoma, lymphoma, and leukemia cell lines.
