Fmoc-Trp(Boc)-Thr(Psi(Me,Me)Pro)-Oh

Catalog Number: (B-4320.0005BA)
Supplier: Bachem Americas
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.

Fmoc-Tyr(So2(Oneopentyl))-Oh

Supplier: Bachem Americas
Description: Fmoc-Tyr(SO₃nP), a protected derivative of sulfotyrosine. The neopentyl ester is stable under the conditions of Fmoc-SPPS including the TFA-cleavage, but can be removed by treatment with aqueous ammonium acetate or sodium acetate. Thus, premature loss of sulfate groups during the final deprotection is prevented.

H-Arg(Pbf)-2-Chlorotrityl, Bachem

Supplier: Bachem Americas
Description: H-Arg(Pbf)-2-chlorotrityl resin (200-400 mesh) (Low Substitution) 5g, Substitution 0. 20-0. 49 mmol/g, Storage Condition: -20 +/- 5 degree C.

Image Unavailable-F-1475.0250BA

L-Cycloserine

Supplier: Bachem Americas
Description: L-Cycloserine regulates sphingolipide metabolism by inhibiting the key enzyme serine palmitoyltransferase. Both cycloserine enantiomers inhibit 3-ketodihydrosphingosine synthetase (EC 2.3.1.50), though the L-form is the more potent inhibitor of the enzyme. Pérez-Sala et al. studied its inhibitory activity on pyruvate metabolism.
