HTH-01-015 是一种选择性 NUAK1/ARK5 抑制剂 (IC₅₀ 为 100 nM)。HTH-01-015 抑制 NUAK1 的效力比抑制 NUAK2 高 100 倍以上 (IC50>10 μM)。

HTH-01-015 is a selective NUAK1/ARK5 inhibitor (IC 50 is 100 nM). HTH-01-015 inhibits NUAK1 with >100-fold higher potency than NUAK2 (IC50 of >10 μM).

NUAK1 100 nM (IC50)

HTH-01-015 is a specific NUAK1 inhibitor. The related NUAK1 and NUAK2 are members of the AMPK (AMP-activated protein kinase) family of protein kinases that are activated by the LKB1 (liver kinase B1) tumor suppressor kinase. HTH-01-015 inhibits NUAK1 with an IC50 of 100 nM, but does not significantly inhibit NUAK2 (IC50 of >10 μM). In all cell lines tested, HTH-01-015 inhibits the phosphorylation of the only well-characterized substrate, MYPT1 (myosin phosphate-targeting subunit 1) that is phosphorylated by NUAK1 at Ser. In U2OS cells, HTH-01-015 suppresses proliferation and phosphorylation of MYPT1 to the same extent as shRNA-mediated NUAK1 knockdown. In mouse embryonic fibroblasts (MEFs), treatment with 10 μM HTH-01-015 suppresses proliferation and phosphorylation of MYPT1 to the same extent as NUAK1-knockout. To test whether NUAK1 inhibition impair
