  Synthesis of a Reduced Ring Analog of Didemnin B

  摘要：

  As part of investigations directed toward the determination of the essential/nonessential structural features for the bioactivities of didemnin B, we designed a reduced ring analog in which three moieties, namely the tyrosine side chain, the isostatine hydroxyl, and the side chain (L-lactyl-L-prolyl-N-Me-D-leucine), were in their presumed bioactive conformation. In designing the reduced ring analog, we eliminated the leucine-proline portion of the macrocycle core and replaced if with an n-butyl linker in order to elucidate its role. According to MM2 calculations (MacroModel molecular modeling), this analog was of lower energy than the natural product didemnin B, and both structures were superimposable. The synthetic strategy involved four disconnections. Macrocyclization was accomplished at the activated carboxylic acid of the alpha-(alpha-hydroxyisovaleryl)-propionyl unit (HIP) and the protected amine of the n-butyl linker using a modification of Schmidt's protocol. After selective deprotection of the hydroxyl and amino groups of the macrocycle, the peptide side chain was introduced using (benzotriazol-1-yloxy)tris(dimethylamino)phosphonium hexafluorophosphate (BOP) as the activating reagent.

  Synthesis of O-Me Ulongamide B and O-Me Ulongamide C, Natural Modified Cyclodepsipeptides

  摘要：

  Synthesis of O-Me ulongamide B and O-Me ulongamide C, modified natural cyclodepsipeptides, was achieved by a convergent route. The respective dipeptides and tridepsipeptides were coupled, obtaining linear depsipentapeptides, which were then deprotected and cyclized. These compounds were tested against three different types of human carcinoma cells and showed only moderate activity.

  Abstract The syntheses of three modified peptide fragments of the cyclodepsipeptide didemnin B are reported. The HIP and isostatine (1st) units of the didemnin B macrocycle were simplified to a Z-alanine residue and the ester linkage (through threonine of the tetrapeptide) was replaced with amide linkages through the amines of glycine, D-alanine and an ethylenediamine linker. The latter permitted the
