In Vitro

SIAIS117 (0-10 μM, 72 h) inhibits SR, H2228, NCI-H69 and NCI-H1688 cell growth, with IC50 values of 1.7, 46, 799, and 259 nM, respectively[1].
SIAIS117 (0-500 nM, 24 h) inhibits the phosphorylation of ALK and STAT3[1].
SIAIS117 inhibits the growth of G1202R-mutant ALK cell line and degrades G1202R-ALK protein[1].
SIAIS117 (100 nM, 24 h) causes sustained degradation of ALK protein in SR cells[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

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.
