Metabolite Identification (MetID)

分析和鉴定代谢物是支持药物发现和新化合物的发展的关键步骤。代谢物鉴定(MOTID)研究有助于您了解清除机制,解析潜在的活性或反应性代谢物的存在,并观察化合物中的不成比例或独特的代谢物,以更好地理解您的分子的生物转化能力。

Nonclinical Metabolite Identification

  • Soft spot identification
  • 体外交叉物种比较
  • Preclinical AME/ADME

Clinical Metabolite Identification

  • 人类艾美
  • Clinical metabolite identification
  • In vivo cross species comparison

环境代谢物鉴定研究

  • Agro chemical metabolite identification

    • Matrix Matching:减少矩阵通过匹配物种匹配矩阵来促进物种之间代谢物反应的比较。
    • 氘交易所:Characterize metabolites by using deuterated mobile phase to highlight exchangeable protons such as –NH, -OH and –COOH. Supports structural elucidation and differentiation of isomeric metabolites.
    • 三氯化钛:通过使用氯化钛(III)氯化物来证实N-氧化物以减少胺。
    • Metabolite isolation: Isolate specific metabolites to facilitate identification.
    • 酶欺诈孵育酶,通常用β-葡糖醛酸酶(EX Helix PoMatia),以释放代谢物释放糖苷酮,提供有关所提出的代谢物的其他信息。更具体的酶可用于检查诸如硫酸盐或葡糖醛酸等特异性缀合物。
    • TLC.: Gain a secondary method for confirmation using an alternative chromatography method. Can be run in 1 or 2 dimensions, manually or through an automated plate spotter.

    Common Biologics Studies

    • Oligonucleotides- 可能的寡核苷酸类型:单链,双链,siRNA,非天然修饰,靶向结构,改性磷酸糖
    • Peptide- Synthetic or modified peptides (usually 10-15 amino acids). Radiolabel usually required.
    • Antibody drug conjugates- 体外经验,临床前的Adme。yaboapp体育官网通常调查给弹头的代谢或弹头和接头。
