Stable triazolylphosphonate analogues of phosphohistidine
摘要:
Histidine-phosphorylated proteins and the corresponding kinases are important components of bacterial and eukaryotic cell-signalling pathways, and are therefore potential drug targets. The study of these biomolecules has been hampered by the lability of the phosphoramidate functional group in the phosphohistidines and the lack of generic antibodies. Herein, the design and concise synthesis of stable triazolylphosphonate analogues of N1- and N3-phosphohistidine, and derivatives suitable for bioconjugation, are described.
Vinyl carboxylate an acylating reagent for selective acylation of amines and diols
摘要:
Vinyl group of vinyl alkylate (C=2 or 16) and vinyl benzoate have been found to be a good leaving group in acylation of alcohols (40-50% yield) and amines (in 60-90% yield).

(DE) Die Erfindung betrifft neue Phospho- bzw. Phosphono-(N-acyl)-serine der allgemeinen Formel (I) einschliesslich aller enantiomeren und diastereomeren Formen sowie sämtlicher pharmazeutisch einsetzbaren Salze dieser Verbindungen. Anwendungsgebiet ist die chemische und die pharmazeutische Industrie. Die Herstellung der Verbindungen (I) erfolgt durch Acylierung der Aminogruppe der entsprechenden Phospho- bzw. Phosphonoserine oder durch Umsetzung eines Phosphates oder Phosphonates mit einem carboxylgeschützten N-Acyl-serin und anschliessende Abspaltung der Schutzgruppe. Die Verbindungen (I) sind cytostatisch und virostatisch wirksam.(EN) The invention relates to novel phospho and phosphono-(N-acyl)-serines of the general formula (I), including all enantiomeric and diastereomeric forms and all pharmaceutically applicable salts of these compounds. The compounds (I) are produced by acylising the amino group of the corresponding phospho or phosphono serines or by causing a phosphate or phosphanate to react with a carboxyl-protected N-acyl-serine and subsequently separating the protective group. The compounds (I) are cytostatically and virustatically effective.(FR) L'invention concerne de nouvelles phospho- ou phosphono-(N-acyl)-sérines de la formule générale (I), y compris toutes les formes énantiomères et diastéréo-isomères ainsi que tous les sels de ces composés utilisables dans le domaine pharmaceutique. La préparation des composés (I) s'effectue par acylation du groupe amino des phospho- ou phosphonosérines appropriées ou en faisant réagir un phosphate ou phosphanate avec une N-acyl-sérine protégée par un groupe carboxyle et ensuite, par élimination du groupe protecteur. Les composés (I) sont cytostatiquement et virostatiquement actifs.

Peptide-based compounds including heteroatom-containing, three-membered rings efficiently and selectively inhibit specific activities of N-terminal nucleophile (Ntn) hydrolases. The activities of those Ntn having multiple activities can be differentially inhibited by the compounds described. For example, the chymotrypsinlike activity of the 20S proteasome may be selectively inhibited with the inventive compounds. The peptide-based compounds include an epoxide or aziridine, and functionalization at the N-terminus. Among other therapeutic utilities, the peptide-based compounds are expected to display anti-inflammatory properties and inhibition of cell proliferation.
