  Synthesis of Muramyl Peptides Containing meso-Diaminopimelic Acid

  摘要：

  Chain-extension Of L-glutamate aldehyde 3 by means of the Wittig-Homer reaction furnished the desired C-7 dicarboxylic acid derivative, which in turn, after C-C double bond hydrogenation and protecting group manipulation, afforded the 2,6-diaminopimelic acid derivatives (S,R)-9 and (S,S)-9, both with the desired orthogonal protecting group pattern. Synthesis of the muramic acid derivative 15 and attachment of an L-alanine residue furnished muramyl-L-alanine 18. The corresponding 1,6-anhydromuramic acid derivative 26 was obtained similarly. Treatment of these compounds with peptides 28-30 and with the 2,6-diaminopimelic acid containing di- and tripeptides 32a, 32b, and 35 gave the protected muramyl peptides 17, 37, 40, 42, 44, 46, and 49a and 49b, which, after deprotection, afforded the desired target molecules muramyl-L-alanine (38), muramyl-L-alanyl-D-glutamic acid (39), muramyl-L-alanyl-D-glutaminide (41), muramyl-L-alanyl-D-isoglutaminyl-L-lysine (43), muramyl-L-alanyl-D-isoglutaminyl-(2S,6R)-2,6-diaminopimelic acid (45), muramyl-L-alanylL-isoglutaminyl-(2S,6R)-2,6-dian-Anopimelinyl-D-alanine (47), 1,6-anhydromuramyl-L-alanyl-D-isoglutaminyl-(2S,6R)-2,6-diaminopimelic acid (50a), and 1,6-anhydromuramyl-L-alanyl-Disoglutaminyl-(2S,6S)-2,6-diaminiopimelic acid (50b).

• Sur les relations entre structure polypeptidique et activité Strépogénique. 1. Peptides de la cystine

  AbstractThe authors propose for the characterization of strepogenic substances of known composition the specific activity, i. e. the number of WOOLLEY units per μmole.Starting from L‐leucyl‐L‐cystinyl‐L‐leucyl‐L‐valyl‐L‐glutamic acid (of very high strepogenine activity, 400 WOOLLEY units per mg, 230 WOOLLEY units per μmole) seven peptides have been synthesized by suppression and/or replacement of amino acid residues. A study of the relation between activity and structure of these peptides shows that: In this group cystine is an indispensable element for activity. This amino acid must either be linked on each side to leucine residues or linked by its carboxyles to leucine, its amino groups being free. From these results, the conception emerges that the strepogenine polypeptides may be characterized by an amino acid (in this group of peptides, cystine) which must be linked to particular amino acid residues. If this conception is correct, there should exist several types of strepogenines depending on the nature of the amino acid essential for their activity.
