  4. KRA-533

KRA-533 is a potent KRAS agonist. KRA-533 binds to the GTP/GDP binding pocket in the KRAS protein to prevent GTP cleavage, resulting in the accumulation of constitutively active GTP-bound KRAS that triggers both apoptotic and autophagic cell death pathways in cancer cells.

Descripciòn

IC50 & Target

KRAS[1]
In Vitro

KRA-533 (10 μM; 48 hours; HCC827 cells) enhances KRAS activity to a greater extent[1].
? KRA-533 (0~15 μM; 48 hours; H157 cells) enhances KRAS activity in a dose-dependent manner, which is associated increased levels of pERK, ratio of active caspase 3/procaspase 3 and PARP cleavage, leading to apoptotic cell death[1].
? KRA-533 (10 μM; 10 days; H292 cells) mediates cell growth suppression than those without KRAS mutation. KRA-533 (5~15 μM) can directly bind to WT, G12C, G12D and G13D mutant KRAS proteins. KRA-533 activates WT KRAS to increase its activity in a dose-dependent manner. KRA-533 further enhances the activities of active KRAS mutants[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.
