Biological Activity

BI-2493 is a structural analogue of BI-2865 and a highly selective pan-KRAS inhibitor. BI-2493 can attenuate tumor growth. BI-2493 can be used for cancer iseases research.

In Vitro

BI-2493 inhibits the proliferation with IC50 values < 140 nM in Ba/F3 cell lines made dependent on KRAS by transfection of different mutant KRAS oncogenes (e.g., KRAS G12C, KRAS G12D, KRAS G12V)[1].

In Vivo

BI-2493(90 mg/kg; gavage) attenuats tumour growth in mice bearing KRAS G12C, G12D, G12V and A146V mutant models, without causing apparent toxicity to the mice[1].
