What is BAY-985?

Biological Activity

BAY-985 is a potent and highly selective TBK1/IKKε inhibitor. It is highly potent against TBK1 (IC50 = 2 nM, low ATP assay; 30 nM, high ATP assay) and IKKε (IC50 = 2 nM) and also in mechanocellular phosphorylation of interferon regulatory factor 3 (pIRF3) assays High potency (IC50 = 74 nM) and anti-proliferative effect on SK-MEL-2 cells (IC50 = 900 nM).

in vitro

BAY-985 inhibits FLT3, RSK4, DRAK1, and ULK1 with IC ₅₀ s of 123, 276, 311, and 7930 nM, respectively.
BAY-985 inhibits the cellular phosphorylation of interferon regulatory factor 3 (IRF3) with an IC ₅₀ of 74 nM.
BAY-985 is active in cellular mechanistic assay and shows anti-proliferative activity in a few cancer cells lines with IC ₅₀ s of 900 and 7260 nM for SK-MEL2 (NRAS and TP53 mutated) and ACHN (CDKN2A mutated) cells, respectively.
