Biological Activity
BI-2865 is a derivative with a prolinol substituent and a pyrimidine linker. BI-2865 has direct ionic interaction with E62, and a water-mediated hydrogen bond network with the side chain of R68 and the main chain carbonyl of Q61, as shown in Co-crystal structures of BI-2865 bound to KRAS[1].
BI-2865 (5 days) inhibits the proliferation of G12C, G12D or G12V mutant KRAS expressing BaF3 cells in the presence of IL-13, with a mean IC50 of roughly 140 nM[1].

Comparison of SIMPL2 and NanoBiT in evaluating the KRAS inhibitor BI2865 (0-1 μM). SIMPL2 stable cells expressing IC-β9-KRAS(WT)/β10-IN-RBD were simultaneously treated with both doxycycline and BI2865 for 5 h at the indicated concentrations followed by luminescence measurement. In contrast, the expression of SmBiT-KRAS(WT)/LgBiT-RBD was induced for 16 h in NanoBiT stable cells, followed by BI2865 treatment. Data are presented as mean ± s.d. with n = 4 biological replicates and were fitted into a four-parameter inhibitor-response model
