HTH-02-006 is a NUAK2 inhibitor, with an IC50 value of 126 nM. HTH-02-006 inhibits NUAK2-mediated signaling by reducing phosphorylation of its substrate MYPT1 at S445 and downstream MLC. HTH-02-006 shows growth inhibitory efficacy in YAP-high cancer cells (HuCCT-1, SNU475). HTH-02-006 significantly suppresses YAP-induced hepatomegaly (reduced liver/body weight ratio) in TetO-YAP S127A transgenic mice and demonstrates significant anti-tumor efficacy in mice bearing HMVP2 prostate cancer allografts. HTH-02-006 can be used for the study of liver cancer and prostate cancer.

IC50 & Target[1]

NUAK2

126 nM (IC50)

In Vitro

HTH-02-006 inhibits NUAK2 kinase activity with an IC50 of 126 nM in vitro, as measured by reduced [γ-32P]ATP incorporation into Sakamototide in a dose-dependent manner[1].
HTH-02-006 (0.5-16 μM, 120 h) reduces phosphorylated MYPT1 (S445) and phosphorylated MLC levels in SNU475 cells, inhibiting actomyosin cytoskeleton activation[1].
HTH-02-006 (0.5-16 μM, 120 h) exhibits higher growth inhibition efficacy in YAP-high liver cancer cells (HuCCT-1, SNU475) compared to YAP-low cells (HepG2, SNU398)[1].
HTH-02-006 (0.5-16 μM, 120 h) shows reduced ability to inhibit MYPT1 phosphorylation and cell growth in NUAK2 A236T/A236T knock-in HuCCT-1 cells (drug-resistant mutant) compared to wild-type HuCCT-1 cells[1].
HTH-02-006 (0.5-20 μM, 9 days) exhibits dose-dependent inhibitory effects on the growth of LAPC-4, 22RV1, and HMVP2 prostate cancer cell spheroids, with IC50 values of 4.65 μM, 5.22 μM, and 5.72 μM respectively[2].
HTH-02-006 (1-10 μM) prevents YAP activation in HMVP2 cells, and downregulates the protein expression of YAP target genes NUAK2 and c-MYC[2].
HTH-02-006 (1-20 μM) significantly reduces the invasion area of HMVP2 cell spheroids into Matrigel, slows wound closure, and completely blocks invasion[2].
HTH-02-006 (10 μM, 72-96 h, medium change every 48 h) reduces the proliferation rate of cancer cells by nearly 50% in 1 mm3 explants[2].

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
