生物活性

LUNA18 is an orally-available cyclic peptide KRAS and ERK inhibitor. LUNA18 phosphorylates ERK and AKT and decreases cell proliferation in RAS-mutated cancer cells. LUNA18 exhibits RAS signal inhibition and potent anti-cancer activities through inhibiting interaction between RAS and guanine nucleotide exchange factors (GEFs) in a mouse xenograft model. LUNA18 shows significant cellular efficacy against cell lines with KRAS genetic alterations, such as colon cancer, stomach cancer, non-small cell lung cancer and pancreaticcancer[1][2][3].

IC50 & Target

IC50: <2 nM (KRASG12D-SOS)[1]
0.043 nM (KRASG12D)[1]

体外研究
(In Vitro)

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.
