Analysis of Dynamic Changes of Scallop (Patinopecten yessoensis) Adductor Muscle and Mantle by Non-Targeted Metabolomics [PDF]

Foods
A non-targeted metabolomics technique was employed to investigate the dynamic metabolite changes of scallop (Patinopecten yessoensis) adductor muscle (SAM) and scallop mantle (SM) during the early (E), middle (M), and late (L) harvest period from June to

A versatile route towards 6-arylpipecolic acids [PDF]

Beilstein Journal of Organic Chemistry
Pipecolic acid is known as a non-proteinogenic amino acid with a secondary amine. It contains a six-membered ring and is, like its five-membered correlate, known for its secondary structure inducing properties, which are particularly useful in the design

In Vitro Fertilisation of Mouse Oocytes in L-Proline and L-Pipecolic Acid Improves Subsequent Development

Cells, 2021
Exposure of oocytes to specific amino acids during in vitro fertilisation (IVF) improves preimplantation embryo development. Embryos fertilised in medium with proline and its homologue pipecolic acid showed increased blastocyst formation and inner cell ...

R97 at “Handlebar” Binding Mode in Active Pocket Plays an Important Role in Fe(II)/α-Ketoglutaric Acid-Dependent Dioxygenase cis-P3H-Mediated Selective Synthesis of (2S,3R)-3-Hydroxypipecolic Acid

Molecules, 2023
Pipecolic acid (Pip) and its derivative hydroxypipecolic acids, such as (2S,3R)-3-hydroxypipecolic acid (cis-3-L-HyPip), are components of many natural and synthetic bioactive molecules. Fe(II)/α-ketoglutaric acid (Fe(II)/2-OG)-dependent dioxygenases can

Preliminary insights on the metabolomics of Trichinella zimbabwensis infection in Sprague Dawley rats using GCxGC-TOF-MS (untargeted approach)

Frontiers in Molecular Biosciences, 2023
Trichinella infections have been documented globally and have been detected in wild and/or domestic animals except Antarctica. There is paucity of information in the metabolic responses of hosts during Trichinella infections and biomarkers for infection ...

The Xanthate Route to Amino Acids

CHIMIA, 2020
The degenerative xanthate addition transfer to alkenes allows the synthesis of a broad range of protected, and in some cases enantiopure, α, β, and γ-amino acids, including proline and pipecolic derivatives, as well as fluorinated congeners and β-lactams.
