NVP-BSK805 是 ATP 竞争性的JAK2抑制剂，对 JAK1 JH1、 JAK2 JH1 (JAK 同源 1)、JAK3 JH1和 TYK2 JH1 的IC50值分别为 31.63、0.48、8.68 和 10.76 nM。

NVP-BSK805 is an ATP-competitive JAK2 inhibitor.

GI50 of<100 nM. NVP-BSK805 blocks the STAT5 phosphorylation at ≥100 nM concentrations, and shows a bias for JAK2 over JAK1 and JAK3 inhibition in the JAK2V617F-mutant cell lines. NVP-BSK805 (5 μM) improves P-gp inhibitory activity. NVP-BSK805 increases sensitization of drug-resistant KBV20C cancer cells to VIC treatment at 10 μM, and such an effect is more effective than a 5 μM dose.

NVP-BSK805 (150 mg/kg, p.o.) blocks STAT5 phosphorylation, splenomegaly, and leukemic cell spreading in a Ba/F3 JAK2V617F cell-driven mouse model. NVP-BSK805 (50, 75, and 100 mg/kg, p.o.) also suppresses rhEpo-mediated polycythemia and splenomegaly in BALB/c mice.
