M. Ledvina et al., SYNTHESIS AND IMMUNOMODULATING ACTIVITY OF LIPOPHILIC ANALOGS OF ACETYLNORMURAMOYL-L-2-AMINOBUTANOYL-D-ISOGLUTAMINE, Collection of Czechoslovak Chemical Communications, 63(4), 1998, pp. 590-598
Acetylnormuramoyl-L-2-aminobutanoyl-D-isoglutamine (7) and its lipophi
lic 6-O-octadecanoyl (8) and 6-O-(2-tetradecylhexadecanoyl) (9) deriva
tives were prepared and their immunoadjuvant activity and pyrogenicity
were tested. Compounds 8 and 9 are less pyrogenic than muramoyl-dipep
tide (MDP) and norMDP analog 7. Both lipophilic derivatives 8 and 9 ar
e better adjuvants than MDP in cell mediated immunity.
