Synthesis of szentiamide, a depsipeptide from entomopathogenic Xenorhabdus szentirmaii with activity against Plasmodium falciparum [PDF]

open access: yesBeilstein Journal of Organic Chemistry, 2012
The synthesis of the recently characterized depsipeptide szentiamide (1), which is produced by the entomopathogenic bacterium Xenorhabdus szentirmaii, is described. Whereas no biological activity was previously identified for 1, the material derived from

Chromopeptide A, a highly cytotoxic depsipeptide from the marine sediment-derived bacterium Chromobacterium sp. HS-13-94

open access: yesActa Pharmaceutica Sinica B, 2015
A bicyclic depsipeptide, chromopeptide A (1), was isolated from a deep-sea-derived bacterium Chromobacterium sp. HS-13-94. Its structure was determined by extensive spectroscopic analysis and by comparison with a related known compound.

Acetylation of FoxO1 Activates Bim Expression to Induce Apoptosis in Response to Histone Deacetylase Inhibitor Depsipeptide Treatment

open access: yesNeoplasia: An International Journal for Oncology Research, 2009
Histone deacetylase (HDAC) inhibitors have been shown to induce cell cycle arrest and apoptosis in cancer cells. However, the mechanisms of HDAC inhibitor induced apoptosis are incompletely understood. In this study, depsipeptide, a novel HDAC inhibitor,

On-resin multicomponent 1,3-dipolar cycloaddition of cyclopentanone–proline enamines and sulfonylazides as an efficient tool for the synthesis of amidino depsipeptide mimics [PDF]

open access: yesAmino Acids, 2020
Depsipeptides are biologically active peptide derivatives that possess a high therapeutic interest. The development of depsipeptide mimics characterized by a chemical diversity could lead to compounds with enhanced features and activity. In this work, an

Depsipeptide Nucleic Acids: Prebiotic Formation, Oligomerization, and Self-Assembly of a New Proto-Nucleic Acid Candidate

open access: yesJournal of the American Chemical Society, 2021
The mechanism by which informational polymers first formed on the early earth is currently unknown. The RNA world hypothesis implies that RNA oligomers were produced prebiotically, before the emergence of enzymes, but the demonstration of such a process ...

Total Synthesis of the Marine Cyclic Depsipeptide Lagunamide D [PDF]

open access: yesMarine Drugs
Lagunamide D is a structurally distinct 26-membered cytotoxic cyclic depsipeptide, originally isolated from a marine cyanobacterium. It exhibits potent antiproliferative activity in the low nanomolar range against A549 human lung adenocarcinoma cells and

Total Synthesis of the Antitumor Depsipeptide FE399 and Its S‐Benzyl Derivative: A Macrolactamization Approach

open access: yesEuropean Journal of Organic Chemistry, 2020
An efficient and practical method for the synthesis of (9R,14R,17R)-FE399, a novel antitumor bicyclic depsipeptide, was developed. A 2-methyl-6-nitrobenzoic anhydride (MNBA)-mediated dehydration condensation reaction was effectively employed for the ...

Mirror image supramolecular helical tapes formed by the enantiomeric-depsipeptide derivatives of the amyloidogenic peptide amylin(20–29)

open access: yesTetrahedron Letters, 2008
Factors that determine the chirality of supramolecular helical tapes formed by a backbone-modified amylin(20-29) depsipeptide and inverso-depsipeptide, were studied by Fourier transform infrared spectroscopy, circular dichroism and transmission electron ...

Depsipeptide substrates for sortase-mediated N-terminal protein ligation [PDF]

open access: yesNature Protocols, 2014
Technologies that allow the efficient chemical modification of proteins under mild conditions are widely sought after. Sortase-mediated peptide ligation provides a strategy for modifying the N or C terminus of proteins. This protocol describes the use of
