物化性质

  • 稳定性/保质期:
    静脉滴注直接扩张血管,导致潮红、心率加快及血压下降,尤其明显于皮肤和骨骼肌血管的扩张。同时,它能刺激肥大细胞释放组胺;对胃肠平滑肌有强烈收缩作用,增加胃肠蠕动,这与直接作用以及间接兴奋胆碱能神经元有关。该物质还能促进唾液腺、胰液及胰酶的分泌,但会抑制胰泌素。对于胰腺内分泌细胞,它具有直接效应:少量使用时可释放少量生长抑素和胰岛素,并大量释放胰高血糖素;而大量使用则相反。此外,还能够释放垂体加压素、生长激素、催乳素及黄体生长激素。

    名称:
    On-target deuteration for peptide sequencing by laser mass spectrometry
    摘要:
    AbstractHydrogen–deuterium exchange was evaluated as a tool for sequence analysis of peptides by matrix‐assisted laser desorption–ionization utilizing post‐source decay (PSD‐MALDI). The number of exchangeable hydrogens (EH) of precursor ions and product ions can be determined from the mass difference between ion signals originating from the deuterated and the non‐deuterated form of a peptide, resulting in a second dimension of structural information. The reliability of sequence determination by combinatorial algorithms or pattern recognition techniques is considerably increased by employng this ‘EH spectroscopy.’ On‐target deuteration is a simple preparatory step which can be performed reversibly with the already mass‐analysed sample within a few minutes and without consumption of additional sample material. The efficiency of hydrogen–deuterium exchange with this technique is about 98.5%. In addition to supporting sequence analysis, deuteration can be used to investigate fundamental fragmentation mechanisms of peptides in PSD‐MALDI. Inconsistencies with expected fragmentation pathways have been found for fragments a1–a3 of substance P.

  • Strained alkynes derived from 2,2′-dihydroxy-1,1′-biaryls; synthesis and copper-free cycloaddition with azides

    日期:——
    A series of strained alkynes were prepared from 2,2′-dihydroxy-biaryls. Several were characterised by X-ray crystallography, revealing strained C(sp)–C(sp)–C(sp3) bond angles in the range of 163–167°. Their cycloadditions with azides proceed without a catalyst. Functionalised versions of these reagents have potential applications to materials synthesis and bioconjugations.

The amino acid residues responsible for the binding of both Cu+ and Cu2+ in these peptides have been identified based on the density functional theory computed binding energy values of Cu+ and the fragment transformation method predicted binding preference of Cu2+ for individual amino acids.

In this report, we demonstrate that an aprotic ionic liquid serves as a novel reaction solvent for protein bioconjugation without noticeable loss of the biomolecule functions. The ionic liquid bioconjugation approach led to discovery of a novel triph
