Activation of murine kupffer cell tumoricidal activity by liposomes containing lipophilic muramyl dipeptide
Nigel C. Phillips, John Rioux, Ming‐Sound Tsao – 1 September 1988 – The ability of liposomes containing a lipophilic muramyl dipeptide, N‐acetylmuramyl‐L‐alanyl‐D‐isoglutamine‐glycerol dipalmitate, to induce Kupffer cell tumoricidal activity has been investigated. Liposomal N‐acetylmuramyl‐L‐alanyl‐D‐isoglutamine‐glycerol dipalmitate was 16‐fold more potent than liposomal N‐acetylmuramyl‐L‐alanyl‐D‐isoglutamine and 2,400‐fold more potent than N‐acetylmuramyl‐L‐alanyl‐D‐isoglutamine in inducing Kupffer cell tumoricidal activity in vitro.
