NUAK1 Inhibitor

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

WZ4003 is the first potent and highly specific NUAK kinase inhibitor with IC₅₀ of 20 nM/100 nM for NUAK1 (ARK5)/NUAK2, without significant inhibition on other 139 kinases.

MRT199665 is a potent and ATP-competitive, selective MARK/SIK/AMPK inhibitor with IC₅₀s of 2/2/3/2 nM, 10/10 nM, and 110/12/43 nM for MARK1/MARK2/MARK3/MARK14, AMPKα1/AMPKα2, and SIK1/SIK2/SIK3, respectively. MRT199665 causes apoptosis in MEF2C-activated human acute myeloid leukemias (AML) cells. MRT199665 inhibits the phosphorylation of SIK substrate CRTC3 at S370.

Narazaciclib (ON123300), a strong and brain-penetrant multi-kinase inhibitor, inhibits CDK4 (IC₅₀=3.9 nM), Ark5 (IC₅₀=5 nM), PDGFRβ (IC₅₀=26 nM), FGFR1 (IC₅₀=26 nM), RET (IC₅₀=9.2 nM), and FYN (IC₅₀=11 nM). Single agent Narazaciclib causes a dose-dependent suppression of phosphorylation of Akt as well as activation of Erk in brain tumors. Narazaciclib inhibits CDK6 with an IC₅₀ of 9.82 nM.

LRRK2-IN-8 is a LRRK2 inhibitor. LRRK2-IN-8 inhibits LRRK2 (wt) and LRRK2 (G2019) with IC₅₀s lower than 10 nM, and inhibits TYK2 and NUAK1 with IC₅₀s of 10-100 nM.

NUAK1-IN-3 is a potent and selective NUAK1 inhibitor with an IC₅₀ of 0.49 nM. NUAK1-IN-3 also inhibits NUAK2 and JAK3 with IC₅₀ values of 265 and 225 nM. NUAK1-IN-3 engages Glu139 of NUAK1, forms a salt bridge between its bicyclic ring nitrogen and Asp142, and uses a fluorine atom to enhance hydrophobic binding interactions. NUAK1-IN-3 attenuates MYPT1 phosphorylation, suppresses the NUAK1-MYPT1 signaling axis, and inhibits proliferation, migration, and invasion of triple-negative breast cancer cells. NUAK1-IN-3 reverses TGF-β1-induced epithelial-mesenchymal transition (EMT) marker alterations, downregulates Snail and N-cadherin, and upregulates E-cadherin in tumor tissues. NUAK1-IN-3 suppresses tumor growth in triple-negative breast cancer xenograft models. NUAK1-IN-3 can be used for the research of triple-negative breast cancer.

OICR19451 is an orally active dual NUAK1/NUAK2 and MARK2/MARK3 kinase inhibitor, with IC₅₀ values of 12 nM and 10 nM against NUAK1 and NUAK2, and 101 nM and 124 nM against MARK2 and MARK3, respectively. OICR19451 modulates the Hippo signaling pathway, increases the phosphorylation level of YAP, enhances the cytoplasmic localization of YAP/TAZ, and inhibits the expression of oncogenes. OICR19451 inhibits cancer cell growth, reduces metastasis, promotes tumor capsule formation, and improves mouse survival in an orthotopic breast cancer model. OICR19451 can be used for research related to triple-negative breast cancer.

ARUK2010489 (Compound 23) is a potent, selective and brain-penetrant NUAK1 inhibitor with a pIC₅₀ of 8.7. ARUK2010489 also inhibits CDK2, CDK4 and CDK6 activity, with inhibitory rate of 7%, 39% and 26% at 1 μM. ARUK2010489 can be used for the research of neurological disease, such as Alzheimer’s disease (AD).

LRRK2/NUAK1/TYK2-IN-1 (conpound 226) shows inhibitory activity toward LRRK2 (Wt), LRRK2 (G2019), TYK2 and NUAK1, with IC₅₀ values lower than 10 nM. LRRK2/NUAK1/TYK2-IN-1 can be used for autoimmune disease research.

ARUK2010694 (Compound 20) is a potent and selective NUAK1 inhibitor with a pIC₅₀ of 8.7. ARUK2010694 also inhibits CDK2, CDK4 and CDK6 activity, with inhibitory rate of 13%, 63% and 32% at 1 μM. ARUK2010694 can be used for the research of neurological disease, such as Alzheimer’s disease (AD).
