  Structure−Immunosuppressive Activity Relationships of New Analogues of 15-Deoxyspergualin. 1. Structural Modifications of the Hydroxyglycine Moiety

  摘要：

  A series of new analogues of 15-deoxyspergualin (DSG), an immunosuppressive agent currently commercialized in Japan, was synthesized and tested in a graft-versus-host disease (GVHD) model in mice. Using the general concept of bioisosteric replacement, variations of the hydroxyglycine central "C" region were made in order to determine its optimum structure in terms of in vivo immunosuppressive activity. By this way, the malonic derivative 13a was discovered as the first example of a new series of potent immunosuppressive agents encompassing a retro-amide bond linked to the hexyl-guanidino moiety. Structure-activity relationships of this series were studied by synthesizing compounds 13g-i and 13k-s. Variation of the "right-amide" of 13a led to the urea 19a and the carbamates 23 and 27a which proved to be equally active as DSG in our GVHD model. Finally 27a was found to be the most potent derivative, being slightly more active than DSG in a heart allotransplantation model in rats. Due to the absence of chiral center in its structure and to its improved chemical stability compared to DSG, 27a was selected as a candidate for clinical evaluation.

  The proposed structure of galantin I, isolated as a mixture of homologs (1a/1b = 9/1), was shown to be incorrect by total synthesis and was revised twice to finally give 5a and 5c, respectively, by total synthesis.

• Total synthesis of galantin I. Acid-catalyzed cyclization of galantinic acid

  The proposed structure of galantin 1, a peptide antibiotic isolated from Bacillus pulvifaciens as a mixture of congeners (1a with the D-ornithine residue and lb with D-lysine; 1a/1b = 9/1), was shown to be incorrect by total synthesis. The substructure 3a, named galantinic acid, was an artifact, and its correct structure was assumed to be the hydroxylated form, 20a or 20b, by spectroscopic comparisons of synthetic la with natural galantin I. The synthesis of both diastereomers, 4a and 4b, again suggested that the sequence of the spermidine moiety of galantin I should be N5,N8. Finally, the correct structure of galantin I as 5a was confirmed by the synthesis of diastereomers 5a and 5b. The synthesis of 5a was accomplished in a convergent manner by the coupling of the protected forms of the constituent amino acids: D-ornithine, 6b, D-alanine, 23b, 11b, 8c, and 19a. Galantinic acid residue 20a, present in natural galantin 1, was found to undergo cyclization with retention of its C3 configuration under the chemical degradation conditions to give the artifact 3a. In order to elucidate the mode of cyclization of 20a to 3a, the synthesis of 20a and its analogues was accomplished in a stereoselective manner from D-serine. The synthesis was characterized by the stereoselective epoxidation of hydroxymethyl (Z)-allylamine 34 and alpha,beta-unsaturated delta-lactone 39. Acidolysis of 20a, 20b, and their analogues suggested that the stereoselective cyclization of galantinic acid was initiated by the formation of delta-lactone 54, which through the sequence of reactions should afford the artifact 3a.
