  Twenty-two kinds of N-acetylmuramyl-L-alanyl-D-isoglutamine (MDP) analogs were synthesized and their adjuvant activity on the induction of delayed-type hypersensitivity to ABA-N-acetyl-L-tyrosine was examined. The L-alanine residue of MDP could be replaced with certain other amino acid residues without loss of activity. The structureactivity relationship of these compounds is discussed. With respect to replacement of the L-alanine residue of MDP in connection with adjuvant activity, it was shown that (1) amino acids having a suitable side chain were effective, (2) basic amino acids were unfavorable, (3) aromatic amino acids were unfavorable, and (4) acidic amino acids were effective. The D-isoglutamine residue of MDP was considered to be essential for the adjuvant activity. The adjuvant activity was decreased by esterification with methanol of the D-glutamic acid residue of MDP and related N-acetylmuramyldipeptides, but the adjuvant activity of D-glutamic acid diamide analogs was similar to that of MDP and its analogs.

  合成了二十二种N-乙酰胞壁酰-L-丙氨酰-D-异谷氨酰胺(MDP)的类似物,并检验了它们对诱导对ABA＿N-乙酰-L-酪氨酸的迟发型过敏反应的佐剂活性。MDP的L-丙氨酸残基能为某些其他氨基酸残基所置换,而活性不变。讨论了这些化合物的结构-活性关系。关于MDP中L-丙氨酸残基的置换和佐剂活性,表明; (1)具有合适侧链的氨基酸是有效的; (2)碱性氨基酸不是有利的; (3)芳香族的氨基酸不是有利的; (4)酸性氨基酸是有效的。认为MDP的D-异谷氨酰胺残基对佐剂活性是必要的。与MDP和有关N-乙酰胞壁酰二肽的D-谷氨酸残基的酯化作用使佐剂活性降低,但D-谷氨酸二酰胺类似物的佐剂活性与MDP及其类似物的佐剂活性相似。

  ω-(1,4-Benzoquinon-2-yl)alkanoic acids, 2-[10-(5,6-dimethoxy-3-methyl-1,4-benzoquinon-2-yl)decyl]-3-hydroxytetracosanoic acid, all-trans-5,9,13,17-tetramethyl-4,8,12,16-octadecatetraenoic acid, and stearic acid were coupled to the 6-O-position of the carbohydrate moiety of muramyl dipeptide alkyl esters, and 6-O-aminoacylmuramyl dipeptide methyl esters. The aminoacyl residues used were Gly, Leu, Ahx, and Aud. New synthetic methods were developed for ω-(1,4-benzoquinon-2-yl)alkanoic acids such as 22-(5,6-dimethoxy-3-methyl-1,4-benzoquinon-2-yl)docosanoic acid, and the α-branched ω-(1,4-benzoquinone-2-yl) β-hydroxy acid, 2-[10-(5,6-dimethoxy-3-methyl-1,4-benzoquinon-2-yl)decyl]-3-hydroxytetracosanoic acid. The effects of the resulting quinonyl, multiprenylacetyl, and stearoylmuramyl dipetides on the induction of delayed-type hypersensitivity to ABA-Tyr in guinea pigs and the tumor(meth-A)-suppressive activity in syngeneic BALB/c female mice were measured. The results revealed that all these muramyl-dipeptide derivatives retained the adjuvant activity whereas the potent tumor-suppressive activity was observed only in quinonylmuramyl dipeptides, indicating that the 5,6-dimethoxy-3-methyl-1,4-benzoquinone ring is a requisite for the manifestation of the tumor-suppressive activity. The lipophilicity-hydrophilicity balance of the molecule was also important. Among the compounds tested, N-acetyl-6-O-[10-(5,6-dimethoxy-3-methyl-1,4-benzoquinon-2-yl)decanoyl]muramyl-l-valyl-d-isoglutamine methyl ester showed the most potent tumor-suppressive activity. This compound also showed tumor-regressive activity in guinea pigs, and hence is a good candidate for further studies.

  ω-(1,4-苯醌-2-基)烷酸、2-[10-(5,6-二甲氧基-3-甲基-1,4-苯并苯醌-2-基)癸基]-3-羟基二十四面酸、全反式-5,9,13,17-四甲基-4,8,12,16-十八碳四烯酸和硬脂酸被偶联到脂质双肽 muramyl dipeptide 的糖部分6-O位置上，形成了6-O-酰氨基muramyl dipeptide甲酯。所使用的酰氨基残基为甘氨酸、亮氨酸、己二酸和叔丁基胺。开发了新的合成方法来制备ω-(1,4-苯醌-2-基)烷酸，如22-(5,6-二甲氧基-3-甲基-1,4-苯醌-2-基)二十二酸，以及α-分支的ω-(1,4-苯醌-2-基)β-羟基酸，即2-[10-(5,6-二甲氧基-3-甲基-1,4-苯醌-2-基)癸基]-3-羟基二十四酸。测定了这些醌基、多烯丙基乙酰基和硬脂酰基muramyl dipeptide在诱导豚鼠对ABA-酪氨酸迟发型超敏反应和抑制同系BALB/c雌性小鼠肿瘤(meth-A)活性中的作用。结果表明，所有这些muramyl dipeptide衍生物都保留了佐剂活性，而只有醌基muramyl dipeptides显示出较强的肿瘤抑制活性，表明5,6-二甲氧基-3-甲基-1,4-苯醌环对于显现肿瘤抑制活性是必需的。分子的亲脂性-亲水性平衡也很重要。在所测试的化合物中，N-乙酰基-6-O-[10-(5,6-二甲氧基-3-甲基-1,4-苯醌-2-基)癸酰基]muramyl-l-缬氨酸-d-异谷氨酰胺甲酯显示出最强的肿瘤抑制活性。该化合物在豚鼠中也显示出肿瘤退缩活性，因此是一个有前景的研究候选物。
