  Convergent Synthesis of Novel Muramyl Dipeptide Analogues: Inhibition of Porphyromonas gingivalis-Induced Pro-inflammatory Effects by High Doses of Muramyl Dipeptide

  摘要：

  Porphyromonas gingivalis (P.g.)-induced TNF-alpha can be affected by muramyl dipeptide (MDP) in a biphasic concentration-dependent manner. We found that in P.g.-exposed macrophages, treatment with 10 mu g/mL of MDP (MDP-low) up-regulated TNF-alpha by 29%, while 100 mu g/mL or higher (MDP-high) significantly decreased it (16% to 38%). MDP-high was found to affect the ubiquitin-editing enzyme A20 and activator protein 1 (AP1). An AP1 binding site was found in the promoter region of A20. A20 promoter activity was up-regulated after transfection of AP1 cDNA in cells. Four analogues of MDP (3-6) were prepared through a convergent strategy involving the synthesis of two unique carbohydrate fragments, 7a and 7b, using the peptide coupling reagents, EDCI and HOAt. Analogue 4 improved MDP function and P.g.-induced activities. We propose a new signaling pathway for TNF-alpha induction activated after exposing macrophages to both P.g. and MDP-high or analogue 4.

  preparation of diverse N‐substituted muramyl dipeptides (N‐substituted MDPs) from different protected monosaccharides is described. The synthetic MDPs include N‐acetyl MDP and N‐glycolyl MDP, known NOD2 ligands, and this methodology allows for structural variation at six positions, including the muramic acid, peptide, and N‐substituted moieties. The capacity of these molecules to activate human NOD2 in the

  描述了一种灵活的合成策略，该策略可从不同的受保护单糖制备各种N-取代的戊二酰二肽（N-取代的MDP）。合成的MDP包括已知的NOD2配体N-乙酰基MDP和N-甘氨酰基MDP，这种方法允许在六个位置上进行结构变异，包括山mic酸，肽和N-取代的部分。还研究了这些分子在先天免疫应答中激活人NOD2的能力。结果发现，在N-甘氨酰MDP的C 1位置添加甲基显着增强了NOD2的刺激活性。

In total, 26 MDP analogues were synthesized and bio‐evaluated for the study of human NOD2 stimulation activity in the innate immune response. Interestingly, MDP derivatives with an ester moiety are found to be more potent than reference compound MDP itself or MDP analogues containing an amide

  The synthesis of two groups (Chart 1, types A and B) of conjugates of MDP (muramyldipeptide) and nor-MDP (normurainyldipeptide) with acridine/acridone derivatives and the synthesis of analogues of desmuramylpeptides (Chart 1, types C and D), containing acridine/ acridone derivatives have been described. In type A conjugates, the hydroxyl group at C6 of the sugar moiety was acylated with acridine/acridone N-substituted omega -aminoalkanocarboxylic acids (Scheme 1), whereas the conjugates of type B (Table 2) and three analogues of type C or D (Scheme 2) have an amide bond formed between the carboxylic group of isoglutamine and the amine function of the respective acridine/acridone derivatives. The preliminary screening data indicate that the analogues of groups A, C, and D exhibit small cytotoxic activity, whereas several analogues of type B, 4b, 4c, 4e, 4g, 4h, 4i, and 4l, exhibiting potent in vitro cytotoxic activity against a panel of human cell lines (Table 4), have been selected by the National Cancer Institute (NCI) Evaluation Committee for further testing. Analogues 4b and 4h were active in the in vivo hollow fiber assay (Table 5). Analogue 3a shows an immunostimulating effect on the cytotoxic activity of the NX cells obtained from the spleen of healthy and Ab melanoma bearing animals.
