生物活性

ALK degrader 2 is an orally active ALK degrader that degrades EML4-ALK levels (DC50 = 8 nM) and nucleophosmin (NPM)-ALK protein levels (DC50 = 102 nM). ALK degrader 2 mediates ALK degradation via the Hsp70 chaperone system and ubiquitin-proteasome pathway. ALK degrader 2 induces significant S-phase cell cycle arrest and apoptosis in H3122 cells. ALK degrader 2 shows anti-tumor activity in mice bearing H3122 xenografts. ALK degrader 2 can be used for the study of non-small cell lung cancer (NSCLC). (Pink: ALK ligand (HY-W754809), Blue: Hyt (HY-W013021), Black: Linker (HY-Y1760), ALK ligand-linker conjugate (HY-175528))[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
