Chemical information

CAS — 206254-79-7.


Bactericidal permeability increasing protein is produced by human leucocytes and possesses both Gram-negative bactericidal and endotoxin-neutralising properties. It also inhibits angiogenesis. Several derivatives have been developed and are under investigation. Opebacan is a modified recombinant fragment of bactericidal permeability increasing protein that is under investigation for the treatment of Crohn’s disease and meningococcal septicaemia. Other derivatives of bactericidal permeability increasing protein are under investigation for retinopathies and acne. Bactericidal permeability increasing protein also possesses antifungal activity.
