In 2010,Chemistry – A European Journal included an article by Tietze, Daniel; Tischler, Marco; Voigt, Stephan; Imhof, Diana; Ohlenschlaeger, Oliver; Goerlach, Matthias; Buntkowsky, Gerd. HPLC of Formula: 87694-50-6. The article was titled 《Development of a Functional cis-Prolyl Bond Biomimetic and Mechanistic Implications for Nickel Superoxide Dismutase》. The information in the text is summarized as follows:
During recent years several peptide-based Ni superoxide dismutase (NiSOD) models have been developed. These NiSOD models show an important structural difference compared to the native NiSOD enzyme, which could cause a completely different mechanism of superoxide dismutation. In the native enzyme the peptide bond between Leu4 and Pro5 is cis-configured, while the NiSOD models exhibit a trans-configured peptide bond between these two residues. To shed light on how the configuration of this single peptide bond influences the activity of the NiSOD model peptides, a new cis-prolyl bond surrogate was developed. As surrogate we chose a leucine/alanine-based disubstituted 1,2,3-triazole, which was incorporated into the NiSOD model peptide replacing residues Leu4 and Pro5. The yielded 1,5-disubstituted triazole nickel peptide exhibited high SOD activity, which was approx. the same activity as its parent trans-configured analog. Hence, the conformation of the prolyl peptide bond apparently has of minor importance for the catalytic activity of the metallopeptides as postulated in literature. Furthermore, it is shown that the triazole metallopeptide is forming a stable cyanide adduct as a substrate analog model complex. The results came from multiple reactions, including the reaction of (S)-N-Methyl-N-methoxy-2-(tert-butoxycarbonylamino)-4-methylpentanamide(cas: 87694-50-6HPLC of Formula: 87694-50-6)
(S)-N-Methyl-N-methoxy-2-(tert-butoxycarbonylamino)-4-methylpentanamide(cas: 87694-50-6) belongs to amides.HPLC of Formula: 87694-50-6 Amides include many other important biological compounds, as well as many drugs like paracetamol, penicillin and LSD. Low-molecular-weight amides, such as dimethylformamide, are common solvents.
