Muramyldipeptide derivatives and influenza vaccine containing them

摘要

Novel muramyldipeptide derivatives such as [6-0-(2-tetradecylhexadecanoyl)-N-acetylmuramoyl]-L-alanyl-D-glutamide and [6-0-(2-tetradecylhexadecanoyl)-N-acetylmuramoyl]-L-alanyl-N -methyl-D-glutamamide are provided. The muramyldipeptide derivatives are excellent compound as an adjuvant or a constituting component of virosome vaccine. An influenza vaccine comprises a complex of the muramyldipeptide derivative and an influenza virus antigen. The influenza vaccine has excellent antibody-producing capacity and safety. <IMAGE>
