Biochem/physiol Actions
Antibiotic peptide.
MDP-LYS(L18), a synthetic analogue of MDP (muramyl dipeptide) derived from bacterial cell walls, is used as a potent immunoadjuvant that enhances protective immunity through activation of monocyte-macrophage lineage cells, such as dendritic cells.
N-Acetylmuramyl-Ala-D-isoglutaminyl-Nε-stearoyl-Lys, Romurtide, a muramyl dipeptide analogue, is a granulocyte-macrophage colony-stimulating factor and a TNF-α inducer.

The novel applications of a muramyl dipeptide analogue, romurtide, were investigated. When mice were intravenously injected with 10-1000 micrograms/mouse of romurtide as a primer and 3 KE/mouse of OK-432 as a trigger, systemic tumor necrosis factor-alpha (TNF-alpha) activity was increased.

MDP-Lys (N2-[(N-acetylmuramyl)-L-alanyl-D-isoglutaminyl]-N6-stearoyl-L-lysine), a macrophage activator, is a lipophilic derivative of muramyl dipeptide (MDP). Multilamellar liposome incorporated MDP-Lys was prepared using phosphatidylcholine and phosphatidylserine by conventional film method, and its inhibitory effect on lung metastasis was compared with MDP-Lys as a
