Abstract:
Abstract2,5-Diketopiperazines are the smallest cyclic peptides comprising two amino acids connected via two peptide bonds. They can be biosynthesized in nature by two different enzyme families, either by nonribosomal peptide synthetases or by cyclodipeptide synthases. Due to the stable scaffold of the diketopiperazine ring, they can serve as precursors for further modifications by different tailoring enzymes, such as methyltransferases, prenyltransferases, oxidoreductases like cyclodipeptide oxidases, 2-oxoglutarate-dependent monooxygenases and cytochrome P450 enzymes, leading to the formation

Abstract:
The crystal structures of eight cyclodipeptides are determined, incorporating pipecolic acid or proline and phenylalanine or N-methyl phenylalanine. This set of structures allows the evaluation of the effects on molecular conformation and crystal packing of imino acid ring-size, relative configuration of the two amino acids, and N-methylation. In the non-methylated compounds, hydrogen-bonding interactions form one-dimensional motifs that dominate the packing arrangement. Three compounds have more than one symmetry-independent molecule in the asymmetric unit (Z′ > 1), indicative of a broad a

Abstract:
A series of chiral spirocyclic cyclodipeptides of the general formula I was synthesized; the aim was to determine how the substitution of cyclobutane for cyclopentane in cyclo(-alanyl-1-amino-1-cyclopentanecarbonyl-) would influence the inhibition of the proliferative activity of the caudal morphogenic system (CMS) of Chick embryos. Spirocyclic cyclodipeptides Ia - Il were obtained by cyclization of linear dipeptides IIa - IIf, prepared by condensation of protected amino acids by DCCI method. The inhibition was investigated by the Chick Embryotoxicity Screening Test. The results show generally

Abstract:
A marine bacterium M44 was separated from 30 m deep seawater in the East China Sea (26° 28.3′ N 122° 29.0′ E) in 2006. 16S rDNA gene sequence comparison showed that the strain M44 was a member of the genusSulfitobacterand highly similar to KMM 3554T. A series of experiments demonstrated that this strain M44 had many distinctive characteristics: its cells were gram-negative and mesophilic; its colonies were slightly yellowish, round, convex, and smooth; and it could grow at 10–28°C, pH 6.0–10.0, and in the presence of 0–12.5% (w/v) NaCl; the optimum growth conditions were 25°C and pH 7.0, and t

Le but de ce travail est la mise au point de nouveaux cyclodipeptides a sept chainons.

Une approche intéressante pour synthétiser une grande diversité de DKP consiste à étudier et manipuler les voies de biosynthèse de ces molécules. Les synthases de cyclodipeptides (CDPS) constituent une famille d’enzymes dédiés à la production de cyclodipeptides, qui ont la particularité d’utiliser les ARNt aminoacylés (AA-ARNt) comme substrats.

Abstract:
Cyclodipeptides and their derivatives, the diketopiperazines (DKPs), constitute a large class of secondary metabolites with noteworthy biological activities that are mainly synthesized by microorganisms. The biosynthetic pathways of some DKPs contain cyclodipeptide synthases (CDPSs), a newly defined family of enzymes. CDPSs hijack aminoacyl-tRNAs from their essential role in ribosomal protein synthesis to catalyze the formation of the two peptide bonds of various cyclodipeptides. The aim of the work presented in this thesis manuscript is to characterize the CDPS family. At first, the structura
