Biological Activity

Description HTH-01-015 is a potent and selective NUAK1 inhibitor with IC50 of 100 nM, >100-fold selectivity over NUAK2.
NUAK1 [1] NUAK2 [1]
100 nM >10 μM
In vitro

In HEK-293 cells express NUAK1 as well as NUAK2, HTH-01-015 suppresses NUAK1-mediated MYPT1 phosphorylation. HTH-01-015 suppresses cell migration In NUAK1+/+ MEFs, and inhibit U2OS cell invasion. Moreover, HTH-01-015 inhibits cell proliferation in both cell lines. [1] HTH-01-015 inhibitors markedly restricted cells from entering into mitosis in U2OS cells. [2]


Kinase Assay:[1]
+ Expand

Kinase activity assays:

In vitro activities of purified GST–NUAK1 and GST–NUAK1[A195T] are measured using Cerenkov counting of incorporation of radioactive 32P from [γ-32P]ATP into Sakamototide substrate peptide. Reactions are carried out in a 50 μL reaction volume for 30 min at 30°C and reactions are terminated by spotting 40 μL of the reaction mix on to P81 paper and immediately immersing in 50 mM orthophosphoric acid. Samples are washed three times in 50 mM orthophosphoric acid followed by a single acetone rinse and air drying. The kinase-mediated incorporation of [γ-32P]ATP into Sakamototide is quantified by Cerenkov counting. One unit of activity is defined as that which catalyses the incorporation of 1 nmol of [32P]phosphate into the substrate over 1 h.

  • Cell lines: U2OS cells and MEFs
  • Concentrations: 10 μM
  • Incubation Time: 5 days
  • Method: Cell proliferation assays are carried out colorimetrically in 96-well plates using the CellTiter 96® AQueous Non-Radioactive Cell Proliferation Assay kit following the manufacturer's protocol. Initially, 2000 cells per well are seeded for U2OS cells and 3000 cells per well are seeded for MEFs. The proliferation assays are carried out over 5 days in the presence or absence of 10 μM HTH-01-015.

*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).

Dilution Calculator

Dilution Calculator

Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:

Concentration (start) x Volume (start) = Concentration (final) x Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )

Definitions of molecular mass, molecular weight, molar mass and molar weight:

Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
