Description:
These dipeptide building blocks containing Ser- or Thr-derived oxazolidines (pseudoprolines) proved to be versatile tools for overcoming some intrinsic problems in the field of peptide chemistry. The presence of pseudoprolines within a peptide sequence results in the disruption of β-sheet structures considered as a source of intermolecular aggregation during chain elongation, thus increasing solvation and coupling kinetics in peptide assembly. Therefore, use of pseudoprolines offer new possibilities for accessing large peptides by convergent strategies and chemoselective ligation techniques. Moreover, incorporation of a pseudoproline unit facilitates cyclization of peptides.

Description:
The dipeptides H-Ala-Gln-OH and H-Gly-Gln-OH (N-1070) are stable substitutes for Gln in cell culture media, which tolerate autoclaving and liberate a lower amount of undesired ammonia than Gln. Ala-Gln and Gly-Gln have also found use as Gln sources in parenteral nutrition.

Description:
Phe-Arg is cleaved from bradykinin by angiotensin-converting enzyme (ACE). See also G-3230 and H-1945 for futher cleavage products.

Description:
Mca-PLGL-Dpa-AR-amide is a very sensitive FRET substrate for continuous assays and in situ determination of the matrix metalloproteinase activity. Cleavage at the Gly-Leu bond separates the highly fluorescent Mca group from the efficient 2,4-dinitrophenyl quencher, resulting in an increase in fluorescence intensity. The kcat/Km values for the punctuated metalloproteinase (MMP-7) and for gelatinase (MMP-2), e.g., are 1.7·10⁵ and 6.3·10⁵ M⁻¹s⁻¹, respectively.

Description:
An RGD tumor-targeting peptide, which binds to αvβ3 receptors. c(RGDfK) can be easily conjugated to fluorophore tags, chelators, or carriers. Palecek et al. converted the ε-amino group into the azide by diazo transfer allowing further functionalization by click chemistry. Mercapto groups can be introduced via acylation of c(RGDfK) with S-acetylthioacetic acid (SATA).

Description:
Antimicrobial peptides are produced by plants and most organisms throughout the animal kingdom including humans. Antimicrobial peptides protect against a broad range of infectious agents, as bacteria, fungi, and viruses. The amphibian skin is an especially rich source of antimicrobial peptides. See also the product families: Hepcidins LL-37 and Fragments Tuftsin and Analogs (subfamily).

Description:
Also known as dioxopiperazines, piperazine-2,5-diones or DKPs. Diketopiperazines may occur as by-products during peptide synthesis or during the degradation of peptides. These cyclic dipeptides have been detected as taste-modulating compounds in food, they often show biological activity. DKPs are valuable chiral synthons, employed e.g. in Schöllkopf's versatile bislactim ether approach. They also have found use as catalysts for enantioselective synthesis, e.g. in the asymmetric Strecker reaction. See also the TRH metabolite cyclo(-His-Pro), G-1745, and cyclo(-Asp-Phe), G-1695, the major degradation product of aspartame.
