Depsipeptide

A depsipeptide is a peptide in which one or more of its amide, -C(O)NHR-, groups are replaced by the corresponding ester, -C(O)OR-.[1] Many depsipeptides have both peptide and ester linkages.[2] Elimination of the N–H group in a peptide structure results in a decrease of H-bonding capability, which is responsible for secondary structure and folding patterns of peptides, thus inducing structural deformation of the helix and β-sheet structures.[2][3] Because of decreased resonance delocalization in esters relative to amides, depsipeptides have lower rotational barriers for cis-trans isomerization and therefore they have more flexible structures than their native analogs.[2][3] They are mainly found in marine and microbial natural products.[4]

Example of a depsipeptide with 3 amide groups (highlighted blue) and one ester group (highlighted green). R1 and R3 are organic groups (e. g. methyl) or a hydrogen atom found in α-hydroxycarboxylic acids. R2, R4 and R5 are organic groups or a hydrogen atom found in common amino acids.

Depsipeptide natural products

[edit]
Enterochelin is a depsipeptide that is an iron-transporter.[5]

Several depsipeptides have been found to exhibit anti-cancer properties.[6]

A depsipeptide enzyme inhibitor includes romidepsin, a member of the bicyclic peptide class, a known histone deacetylase inhibitors (HDACi). It was first isolated as a fermentation product from Chromobacterium violaceum by the Fujisawa Pharmaceutical Company.[7]

Etamycin was shown in preliminary data in 2010 to have potent activity against MRSA in a mouse model.[8] Several depsipeptides from Streptomyces exhibit antimicrobial activity.[9][10] These form a new, potential class of antibiotics known as acyldepsipeptides (ADEPs). ADEPs target and activate the casein lytic protease (ClpP) to initiate uncontrolled peptide and unfolded protein degradation, killing many Gram-positive bacteria.[11][12][13]

Depsipeptides can be formed through a Passerini reaction.[14]
