A series of MDP (muramyldipeptide) or nor-MDP (normuramyldipeptide) analogues modified at the C-terminus post of the molecule by a formation of an ester bond between the carboxylic group of isoglutamine and the hydroxyl function of the respective derivatives of 4-carboxamideacridine/9-acridone or 1-nitro-9-hydroxyalkylaminoacridines were synthesized as potential anticancer agents. The compounds O-(1-O-benzyl-N-acetyl-muramyl-L-alanyl-D-gamma-isoglutaminyl)-9-(ethylamino)-1-nitroacridine ester 3j and O-(1-O-benzyl-N-acetyl-muramyl-L-alanyl-D-gamma-isoglutaminyl)-9-propylamino-l-nitroacridine ester 3k exhibited high in vitro cytotoxic activity against a panel of human cell lines, prostate cancer and AIDS-related lymphoma (ARL). Analogue 3j was also active in vivo in the hollow fiber assay. Antitumor activity of both compounds were tested in vivo against difference human tumor xenograft, but only analogue 3k showed in vivo activity against se UACC-62 melanoma in mice.

The synthesis and biological activity of new conjugates of muramyl dipeptide (MDP) and nor-muramyl dipeptide (nor-MDP) with tuftsin and retro-tuftsin derivatives containing isopeptide bond between ε-amino group of lysine and carboxyl group of simple amino acids such as Ala, Gly and Val are presented. We presumed, based on the cytokine profile, that the examined conjugates of tuftsin and MDP were capable of activating antibacterial mechanisms by switching on Th1 immune response. The most active were compounds 11, 14 and 19-23.
