One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, Formula: C4H5N3, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 5469-70-5, Name is 3-Aminopyridazine, molecular formula is C4H5N3
An efficient solid-phase synthesis of peptidyl-N-acetylguanidines for use in native chemical ligation
In the modern protocols of chemical protein syntheses, peptide-alpha-thioesters have been used as key components for the assembly of full-length polypeptides through chemoselective peptide coupling reactions. A variety of thioester precursors have been developed for the synthesis of the peptide-alpha-thioesters by Fmoc solid phase peptide synthesis (Fmoc-SPPS). Recently our group found a peptidyl-N-acetylguanidine as a new peptide-alpha-thioester precursor. This peptide derivative can be converted into a corresponding peptide-alpha-thioester only by treatment with an excess amount of a thiol in aqueous buffers at around neutral pH. This unique property allowed us to envision the practical use of the peptidyl-N-acetylguanidines for the chemical syntheses of proteins; however, an efficient synthetic method has been lacking. Herein, we report an efficient solid-phase synthesis of peptidyl-N-acetylguanidines. This new synthetic method employing selective activation and cleavage of a peptide bond successfully provided peptidyl-N-acetylguanidines from the on-resin protected peptides prepared by standard Fmoc-SPPS. We also evaluated the reactivity of a peptidyl-N-acetylguanidine in native chemical ligation through the synthesis of glucose-dependent insulinotropic polypeptide analogue.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Formula: C4H5N3, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 5469-70-5, in my other articles.
