Optimization of solid-phase synthesis of difficult peptide sequences via comparison between different improved approaches

Autor: A. Hattaba, A. El-Kafrawy, M. F. Anwer, S. Abdel Rahman

Publikováno v: Amino Acids. 33:531-536

Different approaches are applied to avoid the strong aggregation of the difficult peptide sequences, which is considered as the main reason for incomplete acylation and deprotection reactions hindering the synthesis of these sequences. Temporary prot

Synthesis of elastin-like peptides using the liquid phase method

Autor: M. E. Younes, A. Hattaba, S. Abdel Rahman

Publikováno v: Collection of Czechoslovak Chemical Communications. 52:1352-1355

Elastin-like peptides were synthesized by the liquid-phase method using poly(ethylene glycol) monomethyl ether (PEGM) (m.w. 5 000) as solubilizing support which provides an alternative possibility for conformational studies and spectroscopic measurem
