Oxidative Degradation of Thiaproline Derivatives in Aqueous Solutions Induced by•OH Radicals

Autor: Dariusz Pogocki, Krzysztof Bobrowski

Publikováno v: Israel Journal of Chemistry. 54:321-332

The participation of neighboring amino and carboxyl groups in thiazolidyne-4-carboxylic acid (thiaproline) and its two derivatives, thiazolidyne-2-carboxylic acid and thiazolidyne-2,4-dicarboxylic acid, is demonstrated during .OH-radical-induced oxid

Synthesis of bis-spirofused thiapyrrolizidinooxindoles by 1,3-dipolar cycloaddition

Autor: Yu. V. Nelyubina, Konstantin A. Lyssenko, A. A. Shvets, Sergey V. Kurbatov

Publikováno v: Russian Chemical Bulletin. 61:1659-1662

The 1,3-dipolar cycloaddition of unstabilized azomethine ylide, which is generated in situ from isatin and thiaproline, to arylidene derivatives of rhodanine affords bis-spirofused thiapyrrolizidinooxindoles. The 1,3-dipolar addition reactions under

Amino acid derivatives are substrates or non-transported inhibitors of the amino acid transporter PAT2 (slc36a2)

Autor: David T. Thwaites, Kelly M Gatfield, Noel Edwards, Catriona M.H. Anderson, Vadivel Ganapathy, Mark Jevons

Publikováno v: Biochimica et Biophysica Acta

The H+-coupled amino acid transporter PAT2 (SLC36A2) transports the amino acids proline, glycine, alanine and hydroxyproline. A physiological role played by PAT2 in amino acid reabsorption in the renal proximal tubule is demonstrated by mutations in

Autor: Daqing Shi, Guolan Dou, Hai Liu

Publikováno v: Journal of Combinatorial Chemistry. 12:633-637

A series of novel spiropyrrolidines and spirothiapyrrolizidines were synthesized via a three-component 1,3-dipolar cycloaddition reaction of isatin or acenaphthenequinone, sarcosine or thiaproline and 4-hydroxy-6-methyl-3-((E)-3-phenylacryloyl)-2H-py
